Description

Technical Field

[0001] This disclosure relates to the field of oil and gas exploration technology, and in particular to a method, system, equipment and medium for monitoring while drilling data analysis and processing. Background Technology

[0002] In the exploration and development of energy resources such as oil and gas, monitoring while drilling (WWP) technology plays a crucial role in ensuring drilling operation safety, improving operational efficiency and quality. As drilling technology advances into deeper and more complex formations, higher demands are placed on the speed, stability, and reliability of WWP data transmission. Therefore, it is necessary to establish a high-speed WWP data analysis and processing method and system.

[0003] Patent CN114033361A discloses a near-bit multi-parameter downhole monitoring and control system. This system consists of surface equipment and a downhole assembly. The downhole assembly includes a drill bit, a multi-parameter acquisition and measurement transmitting sub, a power drill string, a receiving and transmitting sub, a wireless communication sub, and a non-magnetic drill collar. The measurement and transmitting sub acquires and stores data at preset time intervals and transmits it to a signal receiving antenna. The communication medium between the power drill string and the drilling fluid transmits the received signals to the receiving and transmitting sub, which then transmits the signals to the wireless communication sub via electromagnetic coupling. The wireless communication sub transmits the received signals to the surface equipment as pulse signals via a mud pulse generator. Finally, the surface system processes and analyzes the data. By analyzing the downhole engineering parameters monitored by this invention's real-time monitoring and control system, technicians can adjust drilling parameters in a timely manner, improving drilling efficiency.

[0004] The following problems exist in the existing technology:

[0005] Current downhole data transmission technologies have relatively low speeds, typically ranging from a few bits per second to tens of bits per second. During drilling operations requiring the real-time transmission of large amounts of monitoring data, this speed is insufficient to meet the demands for rapid transmission, leading to data backlog and impacting the timeliness of operational decisions. Furthermore, in complex downhole environments, the data transmission stability of existing technologies is poor. For example, when the wellbore curvature is significant, signals transmitted via mud pulses are easily interfered with, exhibiting signal interruptions or increased delays.

[0006] Existing downhole data transmission technologies typically lack intelligent evaluation mechanisms for monitoring data while drilling and optimization mechanisms for transmission links. They cannot automatically assess whether to adjust transmission methods and parameters based on changes in drilling stages, downhole environment, and data transmission requirements.

[0007] In summary, there is an urgent need for a drilling monitoring data analysis and processing technology solution to improve transmission. Summary of the Invention

[0008] To address the aforementioned issues, this disclosure provides a method, system, equipment, and medium for analyzing and processing monitoring data during drilling.

[0009] Firstly, a method for analyzing and processing monitoring-while-drilling data, the method comprising:

[0010] Based on the geological data of the target well, a completed reference well is determined, and the drilling monitoring data of the completed reference well is used to determine whether to construct a hybrid transmission link;

[0011] When constructing a hybrid transmission link for the target well, several acquisition time points are set during the drilling process of the target well. At each acquisition time point of the target well, it is evaluated whether to switch the transmission method of the monitoring data while drilling from mud pulse transmission to wireless laser transmission.

[0012] When the transmission method of the monitoring data while drilling at a certain acquisition time point of the target well is wireless laser transmission, determine the parameter values ​​of wireless laser transmission and start wireless laser transmission according to the parameter values;

[0013] At the acquisition time point of the next target well where wireless laser transmission is enabled, assess whether to switch back to mud pulse transmission for the transmission of monitoring data while drilling.

[0014] Further geological data for the target well includes: rock layer thickness, formation dip angle, rock density, and mud solids content.

[0015] Furthermore, based on the geological data of the target well, control wells are identified upon completion, including:

[0016] Obtain geological data on the rock layer thickness, formation dip angle, rock density, and mud solids content of all completed wells around the target well, and arrange them in ascending order to obtain a list of the ranges of rock layer thickness, formation dip angle, rock density, and mud solids content for all completed wells.

[0017] Compare the screening ranges for rock layer thickness, formation dip angle, rock density, and mud solids content of the target well with the screening ranges for rock layer thickness, formation dip angle, rock density, and mud solids content of all completed wells in a list.

[0018] Completed wells whose geological data fall within the screening ranges for rock layer thickness, formation dip angle, rock density, and mud solids content of the target well are designated as completed control wells.

[0019] Furthermore, based on the monitoring data while drilling of the control wells after completion, it is determined whether to construct a hybrid transmission link, including:

[0020] Acquire the monitoring data while drilling (WWP) of the completed control wells, including: real-time data flow of the completed control wells at each drilling stage. Difference in transmission rate between completed and control wells Completed well error rate Transmission delay time of the well completed and compared with the well completed

[0021] The comprehensive evaluation value of the monitoring data while drilling for each completed control well is obtained by calculating the following formula:

[0022]

[0023] Among them, Ω a This represents the comprehensive monitoring data evaluation value of the completed control well (a); 'a' represents the number corresponding to the completed control well (a is a positive integer), 'b' represents the number corresponding to each drilling stage (b is a positive integer); 'x' represents the number of completed control wells, and 'z' represents the number of drilling stages; 'q′', 'w′', 'r′', and 't′' are the set standard real-time data flow, standard transmission rate difference, standard bit error rate, and standard transmission delay time of the completed control wells, respectively; 'ω1', 'ω2', 'ω3', and 'ω4' are the set weighting factors for the real-time data flow, transmission rate difference, bit error rate, and transmission delay time of the completed control wells, respectively; 'ω1', 'ω2', 'ω3', and 'ω4' are all greater than 0 and less than 1.

[0024] The comprehensive drilling monitoring data evaluation value of the completed control well is compared with the drilling monitoring data evaluation value of the standard completed control well.

[0025] When the comprehensive monitoring data evaluation value of the completed control well is greater than or equal to the set monitoring data evaluation value of the standard completed control well, it is determined that a hybrid transmission link needs to be constructed.

[0026] When the comprehensive monitoring data evaluation value of the completed control well is less than the set monitoring data evaluation value of the standard completed control well, it is determined that there is no need to build a hybrid transmission link.

[0027] Furthermore, at each acquisition time point in the target well, assess whether to switch the transmission method of the monitoring-while-drilling data from mud pulse transmission to wireless laser transmission, including:

[0028] Obtain the evaluation values ​​of the monitoring data while drilling at each acquisition time point of the target well, and compare the evaluation values ​​of the monitoring data while drilling at each acquisition time point of the target well with the evaluation values ​​of the monitoring data while drilling of the set standard completed control well.

[0029] When the evaluation value of the drilling monitoring data at a certain acquisition time point of the target well is greater than or equal to the evaluation value of the drilling monitoring data of the standard completed control well, the transmission method of the drilling monitoring data at the acquisition time point of the target well needs to be switched from mud pulse transmission to wireless laser transmission.

[0030] If the evaluation value of the monitoring data while drilling at a certain acquisition time point of the target well is less than the evaluation value of the monitoring data while drilling of the standard completed control well, there is no need to switch the transmission method of the monitoring data while drilling at the acquisition time point of the target well from mud pulse transmission to wireless laser transmission.

[0031] Furthermore, obtain the evaluation values ​​of the drilling monitoring data at each acquisition time point of the target well, including:

[0032] Monitoring while drilling (MSWL) data was acquired at various acquisition time points in the target well. The MSWL data included: the real-time data flow rate Q of the target well. c Target well transmission rate difference W c Target well bit error rate R c and target well transmission delay time T c ;

[0033] The evaluation value Ξ of the drilling monitoring data at each acquisition time point of the target well is obtained using the following calculation formula. c :

[0034]

[0035] Where c represents the number corresponding to each acquisition time point, and c is a positive integer; Q′, W′, R′, and T′ are the set target well standard real-time data flow, standard transmission rate difference, standard bit error rate, and standard transmission delay time, respectively; ξ1, ξ2, ξ3, and ξ4 are the set drilling real-time data flow, transmission rate difference, bit error rate, and transmission delay time, respectively; e represents the natural constant; ξ1, ξ2, ξ3, and ξ4 are all greater than 0 and less than 1.

[0036] Furthermore, the parameter values ​​for wireless laser transmission are determined, including:

[0037] Assess the environmental barrier level of the target well at the time of collection, including: Level 1, Level 2, and Level 3;

[0038] When the environmental obstruction level of the target well at the acquisition time point is level one, the transmission power of the wireless laser is increased by the first amplification ratio; at the same time, the beam divergence angle adjustment mechanism is used to adjust the divergence angle of the wireless laser by changing the position of the focusing lens through motor drive, and the divergence angle is reduced by the first reduction ratio.

[0039] When the environmental obstruction level of the target well at the acquisition time point is level two, the transmission power of the wireless laser is increased by the second amplification ratio; at the same time, the beam divergence angle adjustment mechanism is used to adjust the divergence angle of the wireless laser by changing the position of the focusing lens through motor drive, and the divergence angle is reduced by the second reduction ratio.

[0040] When the environmental obstruction level of the target well at the acquisition time point is level three, the transmission power of the wireless laser is increased by the third amplification ratio; at the same time, the beam divergence angle adjustment mechanism is used to adjust the divergence angle of the wireless laser by changing the position of the focusing lens through motor drive, and the divergence angle is reduced by the third reduction ratio.

[0046] The wellbore curvature, wellbore ellipticity, and mud viscosity at the target well's corresponding acquisition time point were normalized, and the normalized wellbore curvature, wellbore ellipticity, and mud viscosity were denoted as σ, ... Substitute υ into the formula The final calculated environmental obstacle assessment value γ for the target well at that collection time was obtained.

[0047] Furthermore, at the acquisition time point of the next target well where wireless laser transmission is enabled, an assessment should be made as to whether the transmission method of monitoring while drilling data should be switched back from wireless laser transmission to mud pulse transmission, including:

[0048] Obtain the evaluation value of the monitoring data while drilling at the acquisition time point of the next target well after wireless laser transmission is enabled, and compare this evaluation value with the evaluation value of the monitoring data while drilling of the set standard well.

[0049] When the evaluation value of the monitoring data while drilling at the acquisition time point of the next target well after wireless laser transmission is enabled is greater than or equal to the evaluation value of the monitoring data while drilling of the set standard well, there is no need to switch back to mud pulse transmission at the acquisition time point of the next target well after wireless laser transmission is enabled.

[0050] When the evaluation value of the monitoring data while drilling at the acquisition time point of the next target well after wireless laser transmission is enabled is less than the evaluation value of the monitoring data while drilling of the set standard well, the wireless laser transmission needs to be switched back to mud pulse transmission at the acquisition time point of the next target well after wireless laser transmission is enabled.

[0051] Secondly, a drilling monitoring data analysis and processing system includes:

[0052] Hybrid transmission link evaluation unit, wireless laser transmission switching evaluation unit, wireless laser transmission enable unit, and mud pulse transmission back-cut evaluation unit;

[0053] The hybrid transmission link evaluation unit determines the completed reference well based on the geological data of the target well, and judges whether to construct a hybrid transmission link based on the drilling monitoring data of the completed reference well.

[0054] The wireless laser transmission switching evaluation unit is used to set several acquisition time points during the drilling process of the target well when a hybrid transmission link is constructed in the target well, and to evaluate at each acquisition time point in the target well whether the transmission mode of the monitoring data while drilling should be switched from mud pulse transmission to wireless laser transmission.

[0064] The comprehensive evaluation value of the monitoring data while drilling for each completed control well is obtained by calculating the following formula:

[0065]

[0067] The comprehensive drilling monitoring data evaluation value of the completed control well is compared with the drilling monitoring data evaluation value of the standard completed control well.

[0068] When the comprehensive monitoring data evaluation value of the completed control well is greater than or equal to the set monitoring data evaluation value of the standard completed control well, it is determined that a hybrid transmission link needs to be constructed.

[0069] When the comprehensive monitoring data evaluation value of the completed control well is less than the set monitoring data evaluation value of the standard completed control well, it is determined that there is no need to build a hybrid transmission link.

[0072] When the evaluation value of the drilling monitoring data at a certain acquisition time point of the target well is greater than or equal to the evaluation value of the drilling monitoring data of the standard completed control well, the transmission method of the drilling monitoring data at the acquisition time point of the target well needs to be switched from mud pulse transmission to wireless laser transmission.

[0073] If the evaluation value of the monitoring data while drilling at a certain acquisition time point of the target well is less than the evaluation value of the monitoring data while drilling of the standard completed control well, there is no need to switch the transmission method of the monitoring data while drilling at the acquisition time point of the target well from mud pulse transmission to wireless laser transmission.

[0074] Furthermore, obtain the evaluation values ​​of the drilling monitoring data at each acquisition time point of the target well, including:

[0075] Monitoring while drilling (MSWL) data was acquired at various acquisition time points in the target well. The MSWL data included: the real-time data flow rate Q of the target well. c Target well transmission rate difference W c Target well bit error rate R c and target well transmission delay time T c ;

[0076] The evaluation value Ξ of the drilling monitoring data at each acquisition time point of the target well is obtained using the following calculation formula. c :

[0077]

[0078] Where c represents the number corresponding to each acquisition time point, and c is a positive integer; Q′, W′, R′, and T′ are the set target well standard real-time data flow, standard transmission rate difference, standard bit error rate, and standard transmission delay time, respectively; ξ1, ξ2, ξ3, and ξ4 are the set drilling real-time data flow, transmission rate difference, bit error rate, and transmission delay time, respectively; e represents the natural constant; ξ1, ξ2, ξ3, and ξ4 are all greater than 0 and less than 1.

[0079] Furthermore, the wireless laser transmission enabling unit is specifically used for:

[0080] Assess the environmental barrier level of the target well at the time of collection, including: Level 1, Level 2, and Level 3;

[0081] When the environmental obstruction level of the target well at the acquisition time point is level one, the transmission power of the wireless laser is increased by the first amplification ratio; at the same time, the beam divergence angle adjustment mechanism is used to adjust the divergence angle of the wireless laser by changing the position of the focusing lens through motor drive, and the divergence angle is reduced by the first reduction ratio.

Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0108] like Figure 1 As shown, a method for analyzing and processing monitoring data while drilling, the method includes:

[0109] S101, Based on the geological data of the target well, determine the completed reference well, and determine whether to construct a hybrid transmission link based on the drilling monitoring data of the completed reference well;

[0110] S102, When constructing a hybrid transmission link for the target well, several acquisition time points are set during the drilling process of the target well. At each acquisition time point of the target well, it is evaluated whether to switch the transmission method of the monitoring data while drilling from mud pulse transmission to wireless laser transmission.

[0111] S103, When the transmission method of the monitoring data while drilling at a certain acquisition time point of the target well is wireless laser transmission, determine the parameter value of wireless laser transmission and start wireless laser transmission according to the parameter value.

[0112] S104, at the acquisition time point of the next target well where wireless laser transmission is enabled, assess whether to switch the transmission method of monitoring while drilling data back from wireless laser transmission to mud pulse transmission.

[0113] The specific implementation is as follows:

[0114] S101, Evaluation of constructing a hybrid transmission link: Obtain geological data of the target well, identify a completed control well based on the geological data of the target well, and finally determine whether to construct a hybrid transmission link based on the drilling monitoring data of the completed control well.

[0115] In one specific embodiment, a completed reference well is identified based on the basic geological data of the target well. The specific process is as follows:

[0116] A1. Obtain geological data for the target well. Collect geological data for the target well, including rock layer thickness, formation dip angle, rock density, and mud solids content; set screening ranges for rock layer thickness, formation dip angle, rock density, and mud solids content for the target well.

[0117] It should be noted that drilling is a crucial means of obtaining accurate geological data beneath the Earth's surface. Drilling operations during exploration should be conducted based on surveying and geophysical exploration. The exploration network should be strategically and systematically laid out according to the exploration stage, project scale, and the complexity of geological conditions, generally following the principles of proceeding from near to far, from shallow to deep, and from sparse to dense. After drilling is completed, a well logging probe is lowered into the well to conduct logging operations. Commonly used logging methods include electrical logging, acoustic logging, radiometric logging, downhole radio imaging, ultrasonic logging, and television logging, thereby obtaining geological data from the target well.

[0118] A2. Identify control wells based on geological data from the target well. Obtain geological data on the formation thickness, dip angle, rock density, and mud solids content of completed wells surrounding the target well, and arrange them in ascending order to obtain a list of the ranges for formation thickness, dip angle, rock density, and mud solids content of all completed wells. Compare the target well's selection ranges for formation thickness, dip angle, rock density, and mud solids content with the list of the ranges for all completed wells. Completed wells whose geological data fall within the selection ranges for formation thickness, dip angle, rock density, and mud solids content of the target well are designated as control wells.

[0119] It should be noted that physical property data of the formation surrounding the wellbore can be obtained through logging methods such as sonic logging, density logging, and neutron logging. Formation interfaces are delineated based on the response characteristics of different formations on the logging curves, and the thickness of each rock layer is obtained. Imaging logging technology can acquire detailed images of the formation surrounding the wellbore, and the images can be analyzed to identify features such as bedding and fractures, thus determining the dip angle of the formation. By emitting gamma rays into the formation and measuring the scattering and absorption of gamma rays by the formation, the bulk density of the rock can be determined. Online monitoring instruments can be used to monitor the solid content and particle size distribution in the drilling mud in real time. These instruments analyze the solid content in the drilling mud by measuring its scattering and absorption characteristics of laser or ultrasonic waves.

[0120] In one specific embodiment, the decision to construct a hybrid transmission link is made based on the monitoring data of the completed control well. The specific process is as follows:

[0121] B1. Acquire the monitoring data while drilling (WWP) of the completed control well, including real-time data flow, transmission rate difference, bit error rate, and transmission delay time for each drilling stage. Record the real-time data flow, transmission rate difference, bit error rate, and transmission delay time for each drilling stage in the completed control well as follows: and 'a' represents the number corresponding to the completed control well, where 'a' is a positive integer, and 'b' represents the number corresponding to each drilling stage, where 'b' is a positive integer. Substituting these values ​​into the following formula, we obtain the comprehensive monitoring data evaluation value Ω for all completed control wells. a :

[0122]

[0123] Where x represents the number of completed control wells, z represents the number of drilling stages; q′, w′, r′, and t′ represent the set standard real-time data flow, standard transmission rate difference, standard bit error rate, and standard transmission delay time for the completed control wells, respectively; ω1, ω2, ω3, and ω4 represent the set weighting factors for the real-time data flow, transmission rate difference, bit error rate, and transmission delay time of the completed control wells, respectively.

[0124] It should be noted that during drilling, specific data acquisition systems are typically used to collect real-time monitoring data. These systems acquire various information from downhole and surface locations using sensors and other devices, converting it into digital signals and storing it. Therefore, the required monitoring data from completed control wells can be directly extracted from the local database or storage device of such data acquisition systems.

[0125] It should also be noted that ω1, ω2, ω3, and ω4 are all greater than 0 and less than 1.

[0126] It should be noted again that, firstly, experts in drilling engineering, data communication, and geological exploration were organized to assess and score the importance of each factor, and then the weights were determined by combining the experts' opinions. For example, five experts were invited to rank the importance of the four factors and assign corresponding scores, and then the average value was calculated to determine the weights. In addition, the experts set the standard real-time data flow, standard transmission rate difference, standard bit error rate, and standard transmission delay time for the control well after drilling completion.

[0127] B2. Compare the comprehensive monitoring data evaluation value of the completed control well with the established monitoring data evaluation value of the standard completed control well. If the comprehensive monitoring data evaluation value of the completed control well is greater than or equal to the established monitoring data evaluation value of the standard completed control well, it is determined that a hybrid transmission link needs to be constructed; if the comprehensive monitoring data evaluation value of the completed control well is less than the established monitoring data evaluation value of the standard completed control well, it is determined that a hybrid transmission link does not need to be constructed.

[0128] It should be noted again that five experts were invited to set the evaluation values ​​of the monitoring data while drilling of the standard completed control well.

[0129] S102, Evaluation of switching wireless laser transmission: If the target well needs to build a hybrid transmission link, then during the drilling process of the target well, several acquisition time points are set, so as to evaluate at each acquisition time point of the target well whether the transmission mode of the monitoring data while drilling should be switched from mud pulse transmission to wireless laser transmission.

[0130] In one specific embodiment, at each acquisition time point of the target well, it is evaluated whether to switch the transmission method of the monitoring while drilling data from mud pulse transmission to wireless laser transmission. The specific process is as follows:

[0131] Acquire the evaluation values ​​of the monitoring data while drilling at each acquisition time point of the target well, and compare the evaluation values ​​of the monitoring data while drilling at each acquisition time point of the target well with the evaluation values ​​of the monitoring data while drilling at a set standard completed control well. If the evaluation value of the monitoring data while drilling at a certain acquisition time point of the target well is greater than or equal to the evaluation value of the monitoring data while drilling at a set standard completed control well, then the transmission mode of the monitoring data while drilling at that acquisition time point of the target well needs to be switched from mud pulse transmission to wireless laser transmission. If the evaluation value of the monitoring data while drilling at a certain acquisition time point of the target well is less than the evaluation value of the monitoring data while drilling at a set standard completed control well, then there is no need to switch the transmission mode of the monitoring data while drilling at that acquisition time point of the target well from mud pulse transmission to wireless laser transmission.

[0132] In a specific embodiment, the evaluation values ​​of the monitoring data while drilling at each acquisition time point of the target well are obtained. The specific process is as follows: Monitoring data while drilling is acquired at each acquisition time point of the target well, including real-time data flow, transmission rate difference, bit error rate, and real-time transmission delay time; the real-time data flow, transmission rate difference, bit error rate, and transmission delay time at each acquisition time point of the target well are respectively denoted as Q. c W c R c and T c c represents the number corresponding to each acquisition time point, and c is a positive integer; substituting into the following calculation formula, we obtain the evaluation value Ξ of the drilling monitoring data at each acquisition time point of the target well. c :

[0133]

[0134] Where Q′, W′, R′, and T′ are the set standard real-time data flow rate, standard transmission rate difference, standard bit error rate, and standard transmission delay time for drilling, respectively; ξ1, ξ2, ξ3, and ξ4 are the set weighting factors for the set real-time data flow rate, transmission rate difference, bit error rate, and transmission delay time for drilling, respectively; and e represents the natural constant.

[0135] It should be noted that ξ1, ξ2, ξ3, and ξ4 are all greater than 0 and less than 1.

[0136] It should be noted again that, firstly, experts in drilling engineering, data communication, and geological exploration were organized to assess and score the importance of each factor, and then the weights were determined by combining the experts' opinions. For example, five experts were invited to rank the importance of the four factors and assign corresponding scores, and then the average value was calculated to determine the weights. In addition, the experts set the standard real-time data flow rate, standard transmission rate difference, standard bit error rate, and standard transmission delay time for drilling.

[0137] S103, Activation of wireless laser transmission: If the transmission method of the monitoring data while drilling at a certain acquisition time point of the target well needs to be wireless laser transmission, specify the parameter values ​​of wireless laser transmission and start wireless laser transmission according to the values.

[0138] In a specific embodiment, the parameter values ​​for wireless laser transmission are defined, and the specific process is as follows:

[0139] C1. Assess the environmental barrier level of the target well at the time of collection, including Level 1, Level 2, and Level 3.

[0140] C2. If the environmental obstruction level of the target well at the acquisition time is Level 1, the transmission power of the wireless laser is increased by a first amplification ratio of 20%. At the same time, using the beam divergence angle adjustment mechanism, the position of the focusing lens is changed by a motor drive to adjust the divergence angle of the wireless laser, and the divergence angle is reduced by a first reduction ratio of 10% to 20%.

[0141] C3. If the environmental obstruction level of the target well at the acquisition time is level two, the transmission power of the wireless laser is increased by a second amplification ratio of 30%. At the same time, using the beam divergence angle adjustment mechanism, the position of the focusing lens is changed by a motor drive to adjust the divergence angle of the wireless laser, and the divergence angle is reduced by a second reduction ratio of 20% to 30%.

[0142] C4. If the environmental obstruction level of the target well at the acquisition time is level three, the transmission power of the wireless laser is increased by a third amplification ratio of 40%. At the same time, the divergence angle of the wireless laser is adjusted by changing the position of the focusing lens through a motor drive using a beam divergence angle adjustment mechanism, and the divergence angle is reduced by a third reduction ratio of 30% to 40%.

[0143] In one specific embodiment, the environmental obstacle level of the target well at the acquisition time point is assessed, and the specific process is as follows:

[0144] Obtain the environmental obstacle assessment value of the target well at the current acquisition time point, and compare this environmental obstacle assessment value with the assessment value range of each environmental obstacle level in the database. If the environmental obstacle assessment value of the target well at the current acquisition time point falls within the assessment value range of a certain environmental obstacle level in the database, then this environmental obstacle level is recorded as the environmental obstacle level of the target well at that current acquisition time point.

[0145] It should be noted that the database is used to store the assessment value ranges for each environmental obstacle level.

[0146] In a specific embodiment, the environmental obstacle assessment value of the target well at the acquisition time point is obtained, and the specific process is as follows:

[0147] Obtain the environmental obstacle parameters of the target well at the acquisition time point, including wellbore curvature, wellbore ellipticity, and mud viscosity. Input the wellbore curvature, wellbore ellipticity, and mud viscosity of the target well at the acquisition time point into the environmental obstacle assessment value calculation model, and finally output the environmental obstacle assessment value of the target well at the acquisition time point.

[0148] It should be noted that during drilling, downhole tools measure the wellbore's inclination and azimuth angles in real time and transmit the data to the surface promptly. As the drill string advances, downhole tools continuously measure and transmit data, providing drilling engineers with real-time wellbore trajectory information to adjust drilling parameters and control wellbore curvature. After obtaining wellbore data using a caliper logging tool or ultrasonic imaging logging tool, drilling engineers compare and calculate wellbore measurements at the same depth in different directions. Wellbore ellipticity is typically defined as (major axis diameter - minor axis diameter) / average diameter. This method quantifies the ellipticity of the wellbore and assesses its regularity. A rotational viscometer is one of the most commonly used instruments for measuring mud viscosity. It works by rotating a rotor in the mud and measuring the resistance experienced by the rotor to calculate the mud viscosity. Common rotational viscometers include six-speed rotational viscometers, which can measure mud viscosity at different rotation speeds to obtain viscosity values ​​at different shear rates, such as plastic viscosity and apparent viscosity.

[0149] It should also be noted that the calculation process for the environmental obstacle assessment value of the target well at this collection time point is as follows: the wellbore curvature, wellbore ellipticity, and mud viscosity corresponding to this collection time point of the target well are normalized, and the normalized wellbore curvature, wellbore ellipticity, and mud viscosity are denoted as σ, ... Substitute υ into the formula The final calculated environmental obstacle assessment value γ for the target well at that collection time was obtained.

[0150] S104, Evaluation of Mud Pulse Transmission Switchback: At the acquisition time of the next target well where wireless laser transmission is enabled, evaluate whether to switch the transmission method of the monitoring data while drilling back from wireless laser transmission to mud pulse transmission.

[0151] In one specific embodiment, at the acquisition time point of the next target well where wireless laser transmission is enabled, an assessment is made as to whether to switch the transmission method of the monitoring while drilling data back from wireless laser transmission to mud pulse transmission. The specific process is as follows:

[0152] Obtain the evaluation value of the monitoring data while drilling (WWD) at the acquisition time point of the next target well after enabling wireless laser transmission, and compare this evaluation value with the WWD evaluation value of the set standard well. If the WWD evaluation value of the next target well after enabling wireless laser transmission is greater than or equal to the set standard well's WWD evaluation value, then it is not necessary to switch back to mud pulse transmission at the acquisition time point of the next target well after enabling wireless laser transmission; if the WWD evaluation value of the next target well after enabling wireless laser transmission is less than the set standard well's WWD evaluation value, then it is necessary to switch back to mud pulse transmission at the acquisition time point of the next target well after enabling wireless laser transmission.

[0154] Hybrid transmission link evaluation unit 201, wireless laser transmission switching evaluation unit 202, wireless laser transmission activation unit 203, and mud pulse transmission back-cut evaluation unit 204;

[0155] The hybrid transmission link evaluation unit 201 determines the completed reference well based on the geological data of the target well, and judges whether to construct a hybrid transmission link based on the drilling monitoring data of the completed reference well.

[0156] The wireless laser transmission switching evaluation unit 202 is used to set several acquisition time points during the drilling process of the target well when a hybrid transmission link is constructed in the target well, and evaluate at each acquisition time point of the target well whether the transmission mode of the monitoring data while drilling should be switched from mud pulse transmission to wireless laser transmission.

[0157] The wireless laser transmission activation unit 203 is used to determine the parameter values ​​of wireless laser transmission and start wireless laser transmission according to the parameter values ​​when the transmission method of the drilling monitoring data at a certain acquisition time point of the target well adopts wireless laser transmission.

[0158] The mud pulse transmission back-cut evaluation unit 204 is used to evaluate whether to switch the transmission mode of the monitoring data while drilling back from wireless laser transmission to mud pulse transmission at the acquisition time point of the next target well where wireless laser transmission is enabled.
