Description

Technical Field

[0001] The invention belongs to the technical field of well exploration path calibration analysis and relates to a high-precision gyroscope calibration, verification, monitoring and analysis system. Background Art

[0002] As global energy demand continues to grow, oil and gas exploration and development activities are increasingly moving deeper into complex geological areas, posing many challenges to drilling operations. Among them, precise control of the drilling path is the key to ensuring exploration success.

[0003] As a precision instrument for measuring angles and angular velocities, gyroscopes are increasingly used in drilling navigation. However, factors such as the gyroscope's own zero bias stability, scale factor error, and external environmental interference still limit its application in high-precision drilling operations. Therefore, how to effectively calibrate and monitor the working status of the gyroscope in real time to ensure the high accuracy and reliability of its output data has become the key to improving the accuracy and efficiency of drilling operations.

[0004] The existing gyroscope detection systems have the following defects in the real-time calibration analysis of their operating data: 1. They often focus on single factor analysis and lack comprehensive consideration of the comprehensive impact of multi-dimensional factors such as geology, environment, and technology on attitude deviation, resulting in incomplete risk identification and a relatively extensive calibration strategy, which is difficult to meet the high requirements for drilling accuracy under complex geological conditions.

[0005] 2. Currently, most decisions on window side drilling operations rely on experience and judgment, lack scientific data support, and there is often no systematic efficiency indicator prediction model for the selection of side drilling direction, which leads to a highly subjective selection process and may miss the best side drilling path, increasing drilling risks and time costs.

[0006] 3. In terms of monitoring wellbore collapse and changes in mud properties, existing technical means often lag behind the actual situation and cannot reflect wellbore stability issues in real time and accurately. The calibration of drilling deviation data is not timely and accurate enough, which affects the protection effect of the wellbore.

[0007] 4. Currently, fault diagnosis of drilling equipment mostly relies on manual observation and empirical judgment, lacking an accurate quantitative evaluation system, which in turn leads to increased maintenance costs or decreased operating efficiency.

[0008] 5. After calibrating and identifying the drilling path, the existing technology often ignores the continuous tracking and feedback of the calibrated path, and fails to form a closed-loop calibration optimization mechanism. Summary of the invention

[0009] In view of this, in order to solve the problems raised in the above background technology, a high-precision gyroscope calibration, verification, monitoring and analysis system is now proposed.

[0010] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides a high-precision gyroscope calibration, verification, monitoring and analysis system, which includes: a wellbore trajectory detection module, which is used to perform drilling operations according to a preset multi-segment wellbore trajectory through a downhole gyroscope, obtain the actual drilling path, and analyze the actual drilling path deviation coefficient in real time.

[0011] The aperture calibration factor determination module is used to locate the deviation from the aperture position, detect the geological related parameters, environmental related parameters and process related parameters of the deviation from the aperture position, analyze the geological deviation measure, environmental deviation measure and process deviation measure of the deviation from the aperture position, and determine the deviation factors of the drilling path corresponding to the deviation from the aperture position, including geological factors, environmental factors and process factors.

[0012] The geological level calibration analysis module is used to determine the drilling deviation adjustment data of the while drilling gyro according to the geological related parameters of the deviation aperture position.

[0013] The environmental level calibration analysis module is used to identify and compensate for errors caused by environmental changes based on environmental related parameters that deviate from the aperture position.

[0014] The drill tool level calibration analysis module is used to calibrate and identify faults of the drill tool equipment based on process-related parameters that deviate from the aperture position.

[0015] The aperture calibration effect evaluation module is used to collect information statistics on the drilled path, evaluate the path calibration effectiveness index of the current deviation from the aperture position, count the deviations from the aperture position on the drilling completion path trajectory, and then evaluate the comprehensive calibration confidence of the exploration well path.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention determines the drilling deviation position by analyzing the gyroscope attitude data during the drilling process, and then identifies and calibrates the causes of attitude deviation during the exploration process from the geological, environmental, and technological levels, and constructs a complete evaluation framework to enrich the comprehensiveness of risk identification and management effectiveness of the drilling process.

[0017] (2) The present invention determines whether to perform a window side drilling operation by obtaining the drillability of the rock that deviates from the aperture position. When the window side drilling operation needs to be performed, the efficiency indexes of each side drilling direction that deviates from the aperture position are predicted and simulated to screen out the optimal direction path, thereby reducing the risk in the drilling process, ensuring drilling safety, and improving the overall drilling efficiency.

[0018] (3) The present invention reflects the impact of current drilling data on the stability of the wellbore by analyzing the wellbore collapse state and mud property change state of the drilled section corresponding to the deviation from the aperture position, and then determines the drilling deviation adjustment data of the while-drilling gyroscope, which helps to protect the integrity of the wellbore, lay a good foundation for subsequent completion operations and oil and gas production, and extend the life of the oil well.

[0019] (4) The present invention determines the degree of fault of the drilling equipment based on the process deviation measurement of the deviation from the aperture position, and then determines whether to perform data application calibration on the tool equipment or replace the tool, thereby avoiding blind tool replacement or over-calibration and improving the accuracy and pertinence of fault diagnosis.

[0020] (5) The present invention analyzes the calibration effectiveness of subsequent paths of deviated positions to identify whether the calibration method of the current drilling process is reasonable. If it is found that the deviation is still large after calibration, the calibration method can be adjusted in time, thereby continuously optimizing the calibration strategy, which helps to improve the matching degree between the actual trajectory and the planned path.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 As shown, the present invention provides a high-precision gyroscope calibration, verification, monitoring and analysis system, which includes: a wellbore trajectory detection module, an aperture calibration factor determination module, a geological level calibration analysis module, an environmental level calibration analysis module, a drilling tool level calibration analysis module, and an aperture calibration effect evaluation module.

[0025] The wellbore trajectory detection module is connected to the aperture calibration factor determination module, the aperture calibration factor determination module is respectively connected to the geological level calibration analysis module, the environmental level calibration analysis module, and the drilling tool level calibration analysis module, and the aperture calibration effect evaluation module is respectively connected to the geological level calibration analysis module, the environmental level calibration analysis module, and the drilling tool level calibration analysis module.

[0026] The wellbore trajectory detection module is used to perform drilling operations according to a preset multi-segment wellbore trajectory through a while-drilling gyroscope, obtain an actual drilling path, and analyze the deviation coefficient of the actual drilling path in real time.

[0027] In a specific embodiment of the present invention, the analysis step of the actual drilling path deviation coefficient is: using a while drilling gyroscope corresponding to the drilling tool to collect the posture data of the actual drilling path in real time, the posture data including the well inclination angle, azimuth angle, etc.

[0028] Determine the control attitude data and control-related parameters of the while-drilling gyroscope at each drilling stage. The control-related parameters include geological control-related parameters, environmental control-related parameters and process control-related parameters. Each drilling stage includes a preset initial trajectory stage and a calibration trajectory stage after window sidetracking.

[0029] The window side drilling is: during the drilling process, when the main wellbore encounters an undrillable formation or obstacle and cannot continue to move forward in the expected direction, it is necessary to cut a small hole at a certain position on the well wall, and then start a new side wellbore through this small hole. This process is called window side drilling.

[0030] Specifically, each control-related parameter is determined by the well depth position of the drilling path, and each control-related parameter at each well depth position is set to a corresponding specified value. For example, when the actual drilling path corresponds to the drilling position within the depth range of [H1, H2), each control-related parameter of the while drilling gyro drilling tool is set to a first type of initial value; when the actual drilling path corresponds to the drilling position within the range of [H2, H3), each control-related parameter of the while drilling gyro drilling tool is set to a second type of initial value, wherein H1, H2, and H3 are preset depth demarcation values ​​for different well depth positions, respectively.

[0031] The control posture data in the calibration trajectory stage after the window opening sidetracking is based on the posture simulation data of the sidetracking position corresponding to the optimized path as the control index.

[0032] The comparison-related parameters in the calibration trajectory stage after the window opening and side drilling are based on the preset comparison-related parameters of the side drilling position depth as comparison indicators.

[0033] The posture data of the actual drilling path is compared with the control posture data to obtain the comprehensive deviation value of the posture data, and the ratio of the comprehensive deviation value to the preset deviation allowable value is obtained and recorded as the actual drilling path deviation coefficient.

[0034] The aperture calibration factor determination module is used to compare the actual drilling path deviation coefficient with the preset path deviation coefficient threshold, extract the path position point where the actual drilling path deviation coefficient exceeds the preset path deviation coefficient threshold, record it as the deviation from the aperture position, detect the geological related parameters, environmental related parameters and process related parameters of the deviation from the aperture position through the detection tool installed on the drilling gyroscope, analyze the geological deviation measurement degree, environmental deviation measurement degree and process deviation measurement degree of the deviation from the aperture position, and determine the deviation factors of the drilling path corresponding to the deviation from the aperture position, including geological factors, environmental factors and process factors.

[0035] In a specific embodiment of the present invention, the geological related parameters include rock hardness and mud viscosity.

[0036] The environment-related parameters include vibration indicators, drilling pressure indicators, temperature indicators, and magnetic interference intensity.

[0037] The process-related parameters include drilling pressure and rotation speed.

[0038] In a preferred embodiment, the process of determining the deviation factor of the drilling path corresponding to the deviation from the aperture position is as follows: comparing the current deviation from the aperture position with the preset well depth positions, determining the well depth position of the current deviation from the aperture position, and then obtaining the corresponding control related parameters of the well depth position.

[0039] The geological related parameters, environmental related parameters and process related parameters of the deviation from the aperture position are compared with the corresponding control related parameters, and the geological deviation measure, environmental deviation measure and process deviation measure of the deviation from the aperture position are analyzed.

[0040] Exemplarily, the geological deviation measure analysis method for the deviation from the aperture position is: obtain the comprehensive deviation value between the geological related parameters of the deviation from the aperture position and the corresponding geological control related parameters of the well depth position, and then record the ratio between it and the preset comprehensive deviation reference value as the geological deviation measure for the deviation from the aperture position.

[0041] Furthermore, the environmental deviation measure and the process parameter deviation measure are obtained in the same manner as the geological deviation measure of the deviation aperture position.

[0042] The geological deviation measure, environmental deviation measure and process deviation measure of the deviation from the aperture position are compared with the corresponding preset deviation measure thresholds, and the deviation measure factors exceeding the preset deviation measure thresholds are identified and recorded as the deviation factors of the drilling path corresponding to the deviation from the aperture position.

[0043] Exemplarily, the identification of the deviation measurement factor that exceeds the preset deviation measurement threshold is specifically as follows: if the geological deviation measurement of the deviation from the aperture position exceeds the preset deviation measurement threshold corresponding to the geological factor, the geological factor is recorded as the deviation factor of the drilling path corresponding to the deviation from the aperture position; if the environmental deviation measurement of the deviation from the aperture position exceeds the preset deviation measurement threshold corresponding to the environmental factor, the environmental factor is recorded as the deviation factor of the drilling path corresponding to the deviation from the aperture position; if the process deviation measurement of the deviation from the aperture position exceeds the preset deviation measurement threshold corresponding to the environmental factor, the process factor is recorded as the deviation factor of the drilling path corresponding to the deviation from the aperture position.

[0044] The geological level calibration analysis module is used to determine the drilling deviation adjustment data of the while drilling gyroscope according to the geological related parameters of the deviation aperture position.

[0045] In a specific embodiment of the present invention, the content of the drilling deviation adjustment data of the drilling gyro includes: using the propagation characteristics of ultrasonic waves in rocks to determine the rock characteristic value ρ of the deviation from the aperture position j , including rock density, porosity, thickness, etc., and the drillability of rocks that deviate from the aperture position is determined by empirical formulas where ρ j ′ is the reference value of the preset rock characteristic value corresponding to the w-th sub-value, j is the sub-value number of the rock characteristic value, j=1,2,...,w, w is the number of sub-values ​​of the rock characteristic value, e is a natural constant, and the rock structure contour is constructed using geological modeling software based on the rock characteristic values ​​that deviate from the aperture position.

[0046] The deviation factor of the drilling path corresponding to the deviation from the aperture position is obtained. When the deviation factor of the drilling path corresponding to the deviation from the aperture position is a geological factor, the drillability of the rock at the deviation from the aperture position is obtained. If the drillability of the rock at the deviation from the aperture position is lower than the preset drillable hardness, it is determined that the deviation from the aperture position requires window side drilling.

[0047] Each side drilling direction of the rock structure contour is evenly marked, the subsequent path corresponding to each side drilling direction is identified, and the wellbore fracture characteristic data of each side drilling direction is extracted. The wellbore fracture characteristic data includes the wellbore fault width and the crack opening.

[0048] Perform ultrasonic detection on each side drilling direction, receive feedback signals of subsequent paths corresponding to each side drilling direction, and analyze waveform changes of feedback signals corresponding to each side drilling direction, such as amplitude, frequency, phase, etc.

[0049] The well wall fracture characteristic data and feedback signal waveform changes of each side drilling direction are substituted into the 3D geological modeling and simulation software, and virtual drilling is performed on the subsequent path corresponding to each side drilling direction. The efficiency index A of each side drilling direction is obtained in the simulation software. ri, various efficiency indicators including drilling speed, drill bit wear rate, etc. are comprehensively evaluated to determine the preferred path direction, and then the posture simulation data of the preferred path direction is extracted from the simulation software, and subsequent drilling operations are carried out according to the posture simulation data.

[0050] Specifically, the content of performing a comprehensive evaluation to determine the preferred path direction is: comprehensively evaluating the efficiency evaluation coefficient of each side drilling direction Among them A i ′ is the preset reference value corresponding to the i-th efficiency index, r is the number of the side drilling direction, r=1, 2, ..., b, i is the number of the efficiency index, i=1, 2, ..., g, and then the maximum value is screened out from the efficiency evaluation coefficients of each side drilling direction, and the side drilling direction to which the maximum value belongs is obtained, which is recorded as the preferred path direction.

[0051] The present invention determines whether to perform a window side drilling operation by obtaining the drillability of rocks that deviate from the aperture position. When the window side drilling operation needs to be performed, the efficiency indicators of each side drilling direction that deviates from the aperture position are predicted and simulated to screen out the optimal direction path, which can reduce the risk in the drilling process, ensure drilling safety, and improve the overall drilling efficiency.

[0052] In a preferred embodiment, the determination of the drilling deviation adjustment data of the drilling gyro also includes: if the rock drillability of the deviated aperture position is not lower than the preset drillability hardness, then extract the mud viscosity V corresponding to the drilled section of the deviated aperture position and the mud viscosity V0 when the deviated aperture position is not drilled, and compare and evaluate the mud performance deterioration indication Wherein ΔV represents the preset normal deviation of viscosity.

[0053] Obtain the comprehensive fault width l and comprehensive crack opening h of the well wall corresponding to the drilled section at the deviation aperture position from the data recording end of the drilling equipment, and detect the collapse indication of the well wall corresponding to the drilled section Among them, l0 and h0 are the preset reference values ​​of wellbore fault width and fracture opening, respectively.

[0054] Evaluate the drilling force F = d + c of the drill, and compare it with the preset drilling force evaluation value F0. When F> F0, is the control value of each identification indicator of the process-related parameters corresponding to the drilling tool, where R′p is the initial application value of the pth identification indicator of the process-related parameters corresponding to the drilling tool, p is the number of each identification indicator of the process-related parameters, and p=1, 2, ..., a.

[0055] When F<F0, It is the control value of each identification indicator corresponding to the process-related parameters of the drilling tool.

[0056] The present invention reflects the influence of current drilling data on the stability of the wellbore by analyzing the wellbore collapse state and mud property change state of the drilled section corresponding to the deviation aperture position, and then determines the drilling deviation adjustment data of the while drilling gyroscope, which helps to protect the integrity of the wellbore, lay a good foundation for subsequent completion operations and oil and gas production, and extend the life of the oil well.

[0057] The environmental level calibration analysis module is used to identify and compensate for errors caused by environmental changes based on environmental related parameters that deviate from the aperture position.

[0058] In a specific embodiment of the present invention, the corresponding content of identifying and compensating the error caused by environmental changes is: when the deviation factor of the drilling path corresponding to the deviation from the aperture position is an environmental factor, extracting the environmental deviation measure ε1 of the deviation from the aperture position.

[0059] Determine the compensation value of each identification indicator corresponding to the process-related parameters of the drilling tool

[0060] The drilling tool level calibration analysis module is used to perform fault calibration and identification on the drilling tool equipment according to process-related parameters that deviate from the aperture position.

[0061] In a specific embodiment of the present invention, the content of fault calibration identification of drilling equipment includes: when the deviation factor of the drilling path corresponding to the deviation from the aperture position is a process factor, extracting the process deviation measure ε2 of the deviation from the aperture position, comparing it with the preset calibrable measure upper limit value, and when it does not exceed the preset calibrable measure upper limit value, determining that the calibration mode of the drilling equipment is software calibration, and then Calibrate and adjust the identification indicators of the corresponding process-related parameters of the drilling equipment.

[0062] When the process deviation measure of the deviation from the aperture position exceeds the preset calibrable measure upper limit, the calibration mode of the drilling equipment is determined to be the tool replacement mode, and then the drilling equipment is replaced.

[0063] The present invention determines the fault degree of drilling equipment according to the process deviation measurement degree of the deviation from the aperture position, and then determines whether to perform data application calibration on the tool equipment or replace the tool, thereby avoiding blind tool replacement or over-calibration and improving the accuracy and pertinence of fault diagnosis.

[0064] The aperture calibration effect evaluation module is used to collect information statistics on the drilled path, evaluate the path calibration effectiveness index of the current deviation from the aperture position, count the deviations from the aperture position on the drilling completion path trajectory, and then evaluate the comprehensive calibration confidence of the exploration well path.

[0065] In a specific embodiment of the present invention, the method for evaluating the path calibration reliability of the current deviation from the aperture position is as follows: obtaining the wellbore structure status information of the drilled section corresponding to the current deviation from the aperture position from the data recording end of the drilling equipment, the wellbore structure status information includes the measured attitude data, the wellbore buried thickness, and the collapse indication of the well wall, and evaluating the influence factor of the vibration of the deviation from the aperture position based on this. Wherein y0 is the preset reference value corresponding to the wellbore buried thickness, and y′ is the wellbore buried thickness in the wellbore structure status information.

[0066] Identify whether there is a window sidetracking position in the completed path. If there is a window sidetracking position in the completed path, obtain the corresponding attitude simulation data of the window sidetracking position, and extract the measured attitude data corresponding to the calibration trajectory segment between the window sidetracking position and the current deviation aperture position. Compare the measured attitude data corresponding to the calibration trajectory segment with the attitude simulation data corresponding to the window sidetracking position to obtain the comprehensive deviation value corresponding to the attitude simulation data, and obtain the ratio between the comprehensive deviation value and the preset allowable value, which is recorded as the drilling effect compression factor β of the calibration trajectory segment.

[0067] Mark the next deviated aperture position of the current deviated aperture position, extract the distance L between these two adjacent deviated aperture positions, and use this to evaluate the path calibration effectiveness index of the current deviated aperture position Where L0 is the preset reference distance corresponding to the adjacent deviation aperture position.

[0068] In a preferred embodiment, the method for evaluating the comprehensive calibration confidence of the exploration well path is: according to the above-mentioned path calibration effectiveness indicator evaluation method for the current deviation from the aperture position, the path calibration effectiveness indicators of each deviation from the aperture position on the drilling completion path trajectory are obtained in the same way, and the average value is obtained, which is recorded as the comprehensive calibration confidence of the exploration well path.

[0069] Furthermore, the comprehensive calibration confidence of the exploration well path is compared with a preset comprehensive calibration confidence threshold. When the comprehensive calibration confidence of the exploration well path is lower than the preset comprehensive calibration confidence threshold, optimization feedback is performed on the current drilling calibration method.

[0070] On the one hand, the present invention determines the drilling deviation position by analyzing the attitude data of the gyroscope during drilling, and then identifies and calibrates the causes of attitude deviation in the exploration process from the geological, environmental, and technological levels, and builds a complete evaluation framework to enrich the comprehensiveness of risk identification and management effectiveness of the drilling process. On the other hand, the present invention identifies the rationality of the calibration method of the current drilling process by analyzing the calibration effectiveness of the subsequent path of the deviation position. If it is found that the deviation is still large after calibration, the calibration method can be adjusted in time, thereby continuously optimizing the calibration strategy, which helps to improve the matching degree between the actual trajectory and the planned path.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.
