Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of remote control of pressure operation, and particularly relates to a remote pressure operation equipment running state detection and calibration method and system. BACKGROUND

[0002] When pressure operation is performed in a multi-well operation area (such as a shale gas field, a dense oil and gas well group, etc.), the configuration of a separate pressure operation equipment (especially an operation pipe column) for each well will lead to insufficient equipment utilization, and the separate control of multi-well pressure operation will have problems such as chaotic regional management and low operation efficiency. The use of a multi-well collaborative operation and pipe column resource scheduling mode based on remote pressure operation control and multi-well operation pipe column resource sharing is a scheme that can significantly improve the multi-well operation efficiency and pipe column resource limitation.

[0003] In actual application, considering that the service life of the pressure sensing device configured in the operation pipe column is much lower than the service life of the operation pipe column, and as the operation pipe column is continuously scheduled and used between multiple operation wells, the offset of the pressure sensing device will continuously increase, and the remote pressure operation control end cannot correctly determine the well pressure through the pressure sensing device, which leads to incorrect remote command issuance, greatly increasing the difficulty and risk of pressure operation control. Therefore, in the remote control of the multi-well operation and pipe column resource sharing scenario, the pressure sensing device configured in the operation pipe column needs to be continuously detected, calibrated, and maintained and replaced when the calibration amount exceeds the critical value.

[0004] However, the detection and calibration method of the existing pressure sensing device is not applicable in the multi-well operation and pipe string resource sharing scene, which has the following limitations: (1) The detection and calibration of the traditional pressure sensing device usually detects the offset at the current detection time by periodic detection, and the pressure value is calibrated by referring to the offset, but the calibration amount between the adjacent two detection times cannot be accurately estimated; (2) Due to the characteristics of the pressure operation, the pressure sensing device arranged in the operation pipe string will be subjected to the cyclic load of high pressure, high pressure and corrosive fluid for a long time, and the load generated by different operation wells due to different well conditions is also different, and the influence of the pressure sensing device is significantly different. In the multi-well operation and pipe string resource sharing scene, the calibration amount of the pressure sensing device becomes extremely difficult to estimate; (3) When the calibration amount of the pressure sensing device exceeds the critical value (industry regulation is that the error exceeds ±1.5%), the pressure sensing device of the operation pipe string needs to be maintained and replaced, but since the real-time calibration value of the pressure sensing device of each operation pipe string cannot be accurately estimated, the overall state of the pressure sensing device of the shared pipe string resource cannot be monitored and managed. If only the pressure sensor with calibration amount exceeding the critical value is maintained and replaced, and no additional strategy is used for the scheduling and operation task execution allocation management of the operation pipe string, a large number of calibration amounts exceeding the critical value may occur at the same time in a certain period, which may cause a short-term shortage of pipe string resources and affect the normal operation of the pressure operation well in the multi-well operation scene.

[0005] Therefore, how to realize the detection and calibration of the pressure sensing device arranged in the operation pipe string in the multi-well operation and pipe string resource sharing scene, ensure the accuracy of the real-time calibration amount estimation of the pressure sensing device, scientifically and reasonably plan the scheduling and operation task execution allocation of the operation pipe string, improve the calibration amount management efficiency of the multi-well operation pipe string resource, avoid the short-term maintenance and replacement of the pressure sensing device, and reduce the impact on the normal operation of the pressure operation well, is a technical problem that needs to be solved.

[0049] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and do not limit the present application.

[0050] The present application embodiment provides a remote snubbing operation equipment running state detection and calibration method, referring to Figure 1 , Figure 1 The figure is a flowchart of the remote snubbing operation equipment running state detection and calibration method of the present application embodiment.

[0051] The embodiment is a remote pressure operation equipment running state detection and calibration method, which is used for a remote pressure operation control terminal configured to connect several detection and calibration terminals to perform detection and calibration of pressure sensing devices, and includes the following steps:

[0053] S2: access the pipe column inventory database to query the historical pressure operation data, historical detection and calibration data and pressure value calibration curve of each pressure sensing device;

[0054] S3: based on the actual pressure value calibration amount in the historical detection and calibration data of each pressure sensing device in the previous calibration period and the historical pressure operation data in the current calibration period, determine the first pressure value theoretical calibration amount of each pressure sensing device according to the pressure value calibration curve;

[0055] S4: according to the first pressure value theoretical calibration amount, prioritize the several pressure sensing devices of the candidate pipe column configuration of the same type, consider the pressure operation type and pressure operation feature set of each pressure operation task, generate pipe column scheduling strategies for assigning candidate pipe columns of pressure sensing devices for several pressure operation tasks, so that the several pressure sensing devices of the candidate pipe column configuration of each pipe column type meet the step-up requirement and the critical replacement requirement at the end of the target maintenance period based on the first pressure value theoretical calibration amount and the second pressure value theoretical calibration amount determined by the assigned pressure operation task;

[0056] S5: monitor whether the second pressure value theoretical calibration amount of the pressure sensing device corresponding to each candidate pipe column reaches the detection and calibration requirement when completing each pressure operation task, if so, perform pressure value detection and calibration of the pressure sensing device and update the pressure value actual calibration amount.

[0057] It should be noted that the detection and calibration method of the existing pressure sensing device is not applicable in the multi-well operation and pipe string resource sharing scene, and has the following limitations: (1) The detection and calibration of the traditional pressure sensing device usually detects the offset at the current detection time by periodic detection, and calibrates the pressure value by referring to the offset, but the calibration amount between the adjacent two detection times cannot be accurately estimated; (2) Due to the characteristics of pressure operation, the pressure sensing device arranged in the operation pipe string will be subjected to the cyclic load of high pressure, high pressure and corrosive fluid for a long time, and the load generated by different operation wells due to different well conditions is also different, and the influence on the pressure sensing device is significantly different. In the multi-well operation and pipe string resource sharing scene, the calibration amount of the pressure sensing device becomes extremely difficult to estimate; (3) When the calibration amount of the pressure sensing device exceeds the critical value (industry regulation is that the error exceeds ±1.5%), the pressure sensing device of the operation pipe string needs to be maintained and replaced, but since the real-time calibration value of the pressure sensing device of each operation pipe string cannot be accurately estimated, the overall state of the pressure sensing device of the shared pipe string resource cannot be monitored and managed. If only the pressure sensor with calibration amount exceeding the critical value is maintained and replaced, and no additional strategy is adopted for the scheduling and operation task execution allocation management of the operation pipe string, a large number of calibration amounts exceeding the critical value may occur at the same time in a certain period, which will cause a short-term shortage of pipe string resources and affect the normal operation of the pressure operation well in the multi-well operation scene.

[0058] To solve the above problems, the embodiment estimates the real-time first pressure value theoretical calibration amount of each pressure sensing device by querying the historical pressure operation data, historical detection and calibration data and pressure value calibration curve of each pressure sensing device, and estimating in turn based on the pressure value calibration curve, improves the real-time calibration amount estimation accuracy of the pressure sensing device, generates a pipe string scheduling strategy that meets the requirements of step-by-step rise and critical replacement of the second pressure value theoretical calibration amount of the pressure operation task allocation by considering the pressure operation type and pressure operation feature set of each pressure operation task, and performs pressure value detection and calibration of the pressure sensing device, to avoid the situation of a large number of pressure sensing devices being maintained and replaced at the same time in a short period, and realize the detection and calibration of the pressure sensing device arranged in the operation pipe string in the multi-well operation and pipe string resource sharing scene.

[0066] S23: Use the identification information to query the data change relationship between the pressure value calibration amount and the load operation quantization duration obtained by each pressure sensing device in the test stage, and fit to obtain several pressure value calibration curves of each pressure sensing device.

[0067] Further, the pressure sensing device of each category performs a pressure value calibration amount change test in the test stage to obtain the data change relationship between the pressure value calibration amount and the load operation quantization duration;

[0076] In this embodiment, by analyzing each received maintenance cycle with pressure operation task, the pressure operation content is obtained, the historical pressure operation data, historical detection calibration data and pressure value calibration curve of each pressure sensor device are queried, the pressure value actual calibration amount of the previous calibration cycle is marked on the pressure value calibration curve of the current calibration cycle by adopting the previous calibration cycle pressure value actual calibration amount and the pressure operation time of each historical pressure operation in the current calibration cycle, and the pressure value calibration value of the completion position is determined by calculating the pressure operation time until the pressure operation time is completed from the marked position. Based on the pressure value calibration value, the real-time first pressure value theoretical calibration amount of each pressure sensor device is estimated, and the real-time calibration amount estimation accuracy of the pressure sensor device is improved.
