Abstract
Description
Technical Field
[0001] The invention relates to a well gun excitation control method, in particular to a separated well gun excitation control method. Background Art
[0002] Explosive sources have strong enough energy to produce relatively sharp pulses and obtain signals in a wide frequency range, which can be used to obtain good geological data in oil and gas exploration. Therefore, from the 1960s to the present, explosive sources are still one of the main excitation sources for seismic exploration.
[0003] The explosive source uses explosives with strong explosive power as the main material and is detonated by detonators. The remote explosion system is a synchronous excitation control device for the well gun explosive excitation method. Through synchronization technology, when the encoder starts the seismic instrument to start collecting, the decoder instantly releases the high-voltage signal and loads it to the corresponding detonator, thereby detonating the explosive. At present, the widely used remote explosion systems at home and abroad are mainly the ShotPro series and the BoomBox series. When using these two series for explosive excitation, 3-4 people are required to form a group. They follow the order of finding the excitation point, releasing the gun line, connecting the excitation well, charging, alerting, detonating and collecting the gun line. Everyone in the group performs their duties and cooperates to complete the excitation of an explosive source. Due to the large number of well guns that need to be excited every day, multiple groups need to be configured, and each group is assigned corresponding regional tasks. The disadvantages of this control system are: (1) Each blasting group has a large number of people, work and process links. When executing a task in one step, other personnel need to wait, resulting in low work efficiency; (2) When executing the task of detonating explosives, all other personnel need to retreat to a safe distance, which increases time costs; (3) The work efficiency is low, and dozens of blasting groups need to work at the same time to ensure the completion of daily detonation tasks, and the labor intensity is high. Summary of the invention
[0004] The purpose of the present invention is to provide a separate well gun excitation control method and device to improve the well gun excitation efficiency, reduce labor costs, and reduce labor intensity.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is:
[0006] A separate well gun excitation control method comprises the following steps performed in sequence:
[0007] S1: Set the excitation time slot list and import the excitation time slot list into each handheld terminal; set the numbers of all handheld terminals and automatically complete parameter matching by selecting the numbers of the handheld terminals;
[0008] S2: Import the excitation point coordinate information into the handheld terminal, assign tasks according to the excitation time slot of the handheld terminal and the excitation difficulty of the field well gun, and set the excitation authority within the task range of each handheld terminal;
[0009] S3: Based on the previous well and blast survey route, the route is formed into a navigation file and loaded into the handheld terminal, and the well and blast firing sequence and route are formulated according to the mission situation;
[0010] S4: Connect the detonator to the detonator at the excitation point to be excited through the gun line in advance, turn on the power switch of the detonator, and start to detect the status of the detonator after the detonator is initialized, and give a prompt according to the detected detonator status;
[0011] S5: After the detonator is detected to be normal, the blasting device locks the GPS signal and obtains the location coordinate information and GPS timing information of the blasting device;
[0012] S6: After the GPS timing of the handheld terminal is stable, the staff will go to the location of the waiting excitation point according to the GPS navigation and route in the handheld terminal;
[0013] S7: Selecting an excitation point to be excited in the handheld terminal, and the handheld terminal broadcasts a communication instruction containing the coordinate information of the excitation point by wireless means;
[0014] S8: After receiving the broadcast information, the detonator that matches the sent excitation point coordinate information feeds back its current state information and parameter information to the handheld terminal, completing the communication pairing between the detonator and the handheld terminal. The condition for the information to match is that the excitation point coordinate information and the detonator coordinate information are within the allowable coordinate tolerance range;
[0015] S9: The handheld terminal broadcasts the charging command containing the detonator number and the coordinate information of the triggering point in advance according to the set triggering time slot;
[0016] S10: After receiving the charging command, the detonator performs a matching check with its own number and coordinate information. After the two pieces of information match, the detonator starts charging the detonator connected to it;
[0017] S11: After charging is completed, the detonator sends a charging completion message to the handheld terminal. After receiving the charging completion message, the handheld terminal calculates the time difference with the nearest next excitation time slot. If the difference is less than the communication delay time, the detonator instruction is abandoned. If the difference is greater than the communication delay time, the detonator instruction containing the agreed excitation time is sent to the detonator in advance, so that the detonator can receive the detonator instruction before the excitation time slot.
[0018] S12: After receiving the detonation instruction, the detonator discharges the detonator according to the agreed excitation time, and then detonates the detonator. After completing the well gun excitation, the excitation state information is returned;
[0019] S13: Stimulate a new excitation point and execute steps (6) to (12) in a loop.
[0020] As a limitation of the present invention, in S1, the setting method of the excitation time slot list is: setting time slots of the same length according to the number of handheld terminals, or setting time slots of different lengths according to the number of each group of excitation points.
[0021] As a further limitation of the present invention, in S4, the method for setting the prompt is: if the detection is normal, the green indicator light of the detonating device flashes and a "beeping" sound prompt is emitted for 1 to 3 seconds; if the detection is abnormal, the red indicator light of the detonating device flashes and a "beeping" sound prompt is emitted continuously.
[0022] As another limitation of the present invention, in S5, after obtaining the position coordinate information and GPS timing of the detonator, continuous and repeated calculations are performed to improve the positioning accuracy.
[0023] As a limitation of the present invention, in S5, the method for obtaining the GPS position of the detonator is: locking the position by building a GPS module in the detonator.
[0024] As a limitation of the present invention, in S5, the method for obtaining the GPS position of the detonator is: manually writing the coordinates of the excitation point into the detonator.
[0025] As a further limitation of the present invention, in S11, the detonation device sends the charging completion information to the handheld terminal and issues an early warning in the form of sound and warning lights to remind the staff to pay attention to whether there are any safety hazards around. If there are any safety hazards, the detonation command is terminated.
[0026] As a further limitation of the present invention, in S11, a detonation instruction containing an agreed excitation time is sent to the detonation device in advance.
[0027] As a third limitation of the present invention, in S12, after receiving the returned excitation status information, the handheld terminal generates and stores the excitation time, coordinate information, and detonator number information of the excitation point, and updates the excitation point status on the excitation point map to display the excitation state.
[0028] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:
[0029] ① The present invention abandons the method based on encoder-decoder synchronous control, separates the excitation step from other steps, connects the detonator with the blasting device in advance when placing the explosives, and then uses the handheld terminal to excite one by one during excitation, which saves the time of connecting the gun line to the detonator and the gun line retracting and releasing, and reduces the waiting time of the excitation personnel; at the same time, the excitation tasks of multiple excitation groups in one area are concentrated on one handheld terminal, which is controlled by remote wireless mode, and distributed management is realized by using multiple handheld terminals to complete the well gun excitation in multiple areas, so as to achieve the excitation of more explosive sources with fewer blasting groups and fewer people in each group. Compared with the traditional centralized control method, it reduces the labor intensity and greatly improves the work efficiency;
[0030] ② The present invention uses the GPS timing-based excitation time slot to perform synchronous control of the handheld terminal, which can more conveniently, safely and effectively manage and control the well gun excitation, and achieve more efficient excitation;
[0031] ③ The present invention can save the steps of retracting and releasing the gun line, and when placing the explosives, the two can be connected, and then directly charged and excited through remote wireless control, which greatly improves work efficiency and saves labor costs.
[0032] In summary, the present invention can improve the working efficiency of well blasting, save labor costs, reduce labor intensity, and is suitable for well blasting in the field of seismic exploration. BRIEF DESCRIPTION OF THE DRAWINGS
[0033] Figure 1 It is a schematic diagram of the control relationship between the handheld terminal, the detonation device and the excitation point in the embodiment of the present invention. DETAILED DESCRIPTION
[0034] The present invention is further described in detail below by specific examples. It should be understood that the described examples are only used to explain the present invention, and are not intended to limit the present invention.
[0035] Embodiment A method for controlling the excitation of a separate well gun
[0036] This embodiment uses a remote wireless control method to load the excitation information of the well gun onto a movable handheld terminal. Through authority setting and automatic matching technology, the interaction and proofreading of the transmitted information are realized, and the remote control excitation of the well gun is performed according to the set excitation time slot. In this way, it is necessary to place the blasting device at the wellhead in advance, and connect the blasting device to the detonator at the excitation point. At the same time, it is necessary to ensure that the blasting device and the detonator are in normal state to provide a guarantee for the normal excitation of the handheld terminal. This method can overcome the defect that the traditional mode requires the cooperation of multiple people to quickly complete the well gun excitation. The excitation management authority of the traditional instrument host is issued to the handheld terminal. Since the blasting device is connected to the detonator in advance, the steps of wiring and gun line retraction and release are reduced during excitation, which greatly improves work efficiency and reduces labor. At the same time, each handheld terminal can have different excitation time slots and have their own excitation authority to prevent the false triggering of the excitation point and improve the data quality. The following is a detailed description of the specific operation method according to the steps.
[0037] like Figure 1 As shown, in this embodiment, it is assumed that there are 2 handheld terminals, numbered A and B. There are 6 detonators, numbered 1, 2, 3, 4, 5, and 6. The detonators numbered 1, 2, and 3 are connected to the detonators at the excitation points 101 / 1001, 101 / 1002, and 101 / 1003 on the excitation route of the handheld terminal A, respectively; the detonators numbered 4, 5, and 6 are connected to the detonators at the excitation points 101 / 1004, 101 / 1005, and 101 / 1006 on the excitation route of the handheld terminal B, respectively.
[0038] S1: First, generate an excitation time slot list according to the number of handheld terminals, the excitation order and the time slot length, and import the excitation time slot list into each handheld terminal. The excitation time slot list is set as follows: set time slots of the same length according to the number of handheld terminals, or set time slots of different lengths according to the number of each group of excitation points to improve the balance of the construction progress. That is, the excitation time slot lengths of handheld terminal A and handheld terminal B can be the same or different. According to the working conditions or workload of the excitation points, set their respective time slot lengths to speed up or balance the progress of the excitation. Then, set the numbers of all handheld terminals, and automatically complete the parameter matching by selecting the number of the handheld terminal. For example, set the numbers A and B for the above two handheld terminals.
[0039] The excitation time slot length of this example refers to the time difference between the current excitation moment and the previous excitation moment in the time domain. In this embodiment, the excitation time slot lengths of handheld terminal A and handheld terminal B are both set to 20s, and the excitation order of handheld terminal A is 1, and the excitation order of handheld terminal B is 2. The software will uniformly define a time base point as the starting point to allocate time slots. The excitation point of handheld terminal A will excite the explosives at the defined time base point plus 20s, 60s, ..., etc. time slots (time points), and the excitation point of handheld terminal B will excite the explosives at the defined time base point plus 40s, 80s ..., etc. time slots (time points). In order to prevent the excitation energy of the latter excitation point from affecting the quality of the data of the previous excitation point, the length setting of the excitation time slot can be adjusted according to the above actual factors. The set excitation time slot list is imported into each handheld terminal, and parameter matching is automatically completed by selecting the number of the handheld terminal to be set. The parameter matching includes the excitation time slot length, excitation order sorting, etc. In addition, other parameters should be set in the handheld terminal software, including the setting of the fixed time before sending the charging command to the excitation time slot, the setting of the coordinate tolerance value, etc., which will be used in the following steps. The sum of the lengths of the time slots of all handheld terminals is an excitation cycle. After an excitation cycle is completed, the first handheld terminal in the ranking will be cycled to continue the excitation. The handheld terminal is a portable electronic device, such as a computer tablet.
[0040] S2: Import the coordinate information of the six excitation points into the software background of each handheld terminal, assign tasks according to the excitation time slot of the handheld terminal and the excitation difficulty of the field well gun, and set the excitation authority within the task range of each handheld terminal. There are usually many excitation points in a large area, and the distributed excitation control of multiple handheld terminals can greatly improve work efficiency.
[0041] In this embodiment, there are 6 well guns in the area that need to be excited. Two handheld terminals are set, and each handheld terminal is assigned to the excitation of 3 well guns. By setting permissions, a handheld terminal is limited to only excite the 3 well guns corresponding to it. The handheld terminal does not have the excitation permission of other well guns to prevent operation errors and excitation of well guns outside the permission. In this embodiment, handheld terminal A can only excite the detonators numbered 1, 2, and 3 corresponding to the excitation points 101 / 1001, 101 / 1002, and 101 / 1003; handheld terminal B can only excite the detonators numbered 4, 5, and 6 corresponding to the excitation points 101 / 1004, 101 / 1005, and 101 / 1006. At the same time, it is also possible to select which excitation point to excite first according to the difficulty of excitation, that is, handheld terminal A can choose to excite any one of the detonators numbered 1, 2, and 3 in the set time slot. Because the handheld terminal only sets that the detonator can be excited in the specified time slot (time point), but which detonator to be excited can be selected according to the actual working situation. When setting the excitation time point, the cumulative display number of the handheld terminal at 0 o'clock UTC (Universal Time) every day can be used as the starting point for superposition setting. For example, the cumulative time number at 0 o'clock UTC is 1684398600, and the first excitation time point of handheld terminal A is to add a time slot on the basis of 1684398600. According to the order of 101 / 1001, 101 / 1004, 101 / 1002, 101 / 1005, 101 / 1003, and 101 / 1006, the excitation time points corresponding to the six excitation points are shown in Table 1. Among them, the example given in Table 1 is that the excitation point 101 / 1001 is excited at the excitation time slot of 1684398620s, and the excitation point 101 / 1002 is excited at the excitation time slot of 1684398660s. It can also be set as needed that the excitation point 101 / 1002 is excited at the excitation time slot of 1684398620s, and the excitation point 101 / 1001 is excited at the excitation time slot of 1684398660s. If the excitation point is not ready, the time slot can also be left blank.
[0042] Table 1 Excitation time points corresponding to each excitation point
[0043]
[0044] S3: Explore the route of well blasting in advance. According to the previous well blasting exploration route, the route is formed into a navigation file and loaded into the handheld terminal. Make a travel plan and firing plan in advance to improve the efficiency of firing points in complex areas. According to the task situation and the plan, make the firing sequence and travel route of well blasting;
[0045] S4: Connect the detonator to the detonator at the excitation point to be excited through the gun line in advance, turn on the power switch of the detonator, initialize the detonator, and start detecting the status of the detonator after the initialization, and give a prompt according to the detected status of the detonator.
[0046] Furthermore, the method for setting the prompt is: if the detection is normal, the green indicator light of the detonator flashes, and a short "beep" sound of 1s, 2s or 3s is issued as a prompt; if the detection is abnormal, the red indicator light of the detonator flashes, and a "beep" sound is continuously issued as a prompt. In this embodiment, after the explosives are placed in the well, the detonator is connected to the detonator. The traditional method requires that the gun line be released and connected to the detonator when it is time to excite, and then alert, charge and excite, and collect the gun line after excitation. Compared with the traditional method, it greatly saves manpower and improves work efficiency.
[0047] S5: After the detonator is detected to be normal, the blasting device locks the GPS signal and obtains the position coordinate information and GPS timing information of the blasting device. After successful acquisition, the coordinate information with higher positioning accuracy is obtained through continuous and repeated calculations. The method for obtaining the GPS position of the blasting device is: locking the position by building a GPS module in the blasting device; or manually writing the excitation point coordinates into the blasting device.
[0048] S6: After the GPS timing of the handheld terminal is stable, the staff will come to the vicinity of the waiting point according to the GPS navigation and route in the handheld terminal, for example, 100 to 150 meters away from the waiting point, and observe the surrounding environment to prevent accidental injury caused by people or animals around.
[0049] S7: Select the excitation point to be excited in the handheld terminal, and the handheld terminal broadcasts the communication instruction containing the coordinate information corresponding to the excitation point by wireless means. For example, if the excitation point to be excited is 101 / 1002 on handheld terminal A, the background of the handheld terminal will broadcast the communication instruction containing the coordinate information corresponding to the excitation point 101 / 1002, such as 39.00231, 116.00348 (the parameters already imported in S2).
[0050] S8: The detonator that matches the coordinate information of the sent excitation point 101 / 1002 is the detonator numbered 2. After receiving the broadcast information, the detonator numbered 2 feeds back its own status information and parameter information to the handheld terminal (such as the working status of the detonator, GPS timing status, number information, etc.), and completes the communication pairing between the detonator and the excitation point. The condition for the information matching referred to in this embodiment is: the coordinate information of the excitation point and the coordinate information of the detonator are within the allowable coordinate tolerance value range, that is, the coordinate tolerance value is 5m set in S1 (set as needed). If the coordinate tolerance value of the coordinate information of the excitation point and the coordinate information of the detonator is less than 5m, the information matches, and if the coordinate tolerance value is greater than 5m, the information does not match. If the information matches, the communication pairing between the detonator and the excitation point is completed. If the information does not match, the command is discarded, and the communication pairing between the detonator and the excitation point is unsuccessful.
[0051] S9: The handheld terminal broadcasts the charging command containing the detonator number and the coordinate information of the detonation point in advance according to the set excitation time slot. In the present embodiment S1, the charging command sending time is set to 10s, so the charging command containing the detonator number 2 and the coordinate information of the excitation point 101 / 1002 is broadcast 10s before the excitation time slot (1684398660s).
[0052] S10: After receiving the charging command, the initiator numbered 2 performs a matching check with its own number and coordinate information. After the two information match, the initiator numbered 2 starts to charge the detonator connected to it. In this embodiment, the received information includes the number 2 of the initiator and the coordinate information corresponding to the excitation point 101 / 1002. Only the initiator numbered 2, whose position coordinates match the coordinate information corresponding to the excitation point 101 / 1002, can charge the detonator.
[0053] S11: After charging is completed, the detonator sends a charging completion message to the handheld terminal. After receiving the charging completion message, the handheld terminal calculates the time difference with the nearest next excitation time slot. If the difference is less than the communication delay time, the detonator instruction is abandoned. If the difference is greater than the communication delay time, the detonator instruction containing the agreed excitation time is sent to the detonator in advance, so that the detonator can receive the detonator instruction before the excitation time slot. After charging is completed, the detonator numbered 2 sends a charging completion message to the handheld terminal A. After receiving the charging completion message, the handheld terminal A calculates the time difference with the nearest next excitation time slot. If the difference is less than the communication delay time, the detonator instruction is abandoned. If the difference is greater than the communication delay time, the detonator instruction containing the agreed excitation time is sent to the detonator numbered 2 before the excitation time slot (such as 10s). Because signal transmission takes time and communication delay time will be generated, the signal transmission delay time is calculated, and the detonator instruction containing the agreed excitation time is sent to the detonator in advance to ensure that the detonator receives the detonator instruction before the preset excitation time slot. In this embodiment, the time to issue the detonation command in advance is determined according to the length of the set excitation time slot, and is generally issued 10 to 20 seconds in advance. If the time difference to the nearest next excitation time slot is less than the communication delay time, even if the detonation command is sent, the detonation device cannot receive the detonation command before the excitation time slot, so the detonation command is abandoned, otherwise the detonation command is sent.
[0054] Furthermore, the detonation device sends the charging completion information to the handheld terminal and issues an early warning in the form of sound and warning lights to remind the staff to pay attention to whether there are any safety hazards around. If there are any safety hazards, the detonation command is terminated.
[0055] S12: After receiving the detonation instruction, the detonator numbered 2 discharges the detonator according to the agreed excitation time, and then detonates the detonator. After completing the well gun excitation, it will return the excitation status information.
[0056] Furthermore, after receiving the returned excitation status information, the handheld terminal generates and stores the excitation time, coordinate information, and detonator number information of the excitation point, and updates the excitation point status on the excitation point map to display the excitation state.
[0057] S13: Stimulate a new excitation point and execute steps (6) to (12) in a loop.
