At present, the following problems generally exist in well head construction operation of well cementing and completion: firstly, the running quantity and the running sequence of key tools (such as centralizers) are strictly carried out according to a construction design scheme, and due to the fact that real-time monitoring and error prompt are lacked in the construction process, the construction quality is affected by human errors such as the fact that well fixing and completion tools are mistakenly run and are not run; secondly, in the pipe string screwing process, serious underground accidents such as loosening of the pipe string and the like can be caused by human errors such as inaccurate screwing torque and improper screwing; and thirdly, the processes of tool running and pipe string buckling lack real-time effective supervision of the first party.
The existing wellhead construction monitoring means for fixed completion well is to monitor the field operation through a camera, and then, to remotely transmit the monitoring image to a first monitoring system, so that the first staff can conveniently record and check, but at the same time, the construction process is patrolled irregularly by the supervision of the construction well field or the first staff. The drawback of this approach is the large amount of manual work; the video monitoring cannot accurately control construction details, and cannot timely and effectively find construction errors and give an alarm; the construction process can only be performed at regular time, and real-time monitoring of the whole process cannot be realized.
To address the above-mentioned problems, the present invention proposes a system and method for monitoring make-up and run-in operations of a completion tool.

Example one
Fig. 1 is a schematic diagram of the overall architecture of a system for monitoring make-up and run-in operations of a completion tool in accordance with an embodiment of the present invention. FIG. 2 is a schematic illustration of an environment in which a system for monitoring make-up and run-in operations of a completion tool according to an embodiment of the present application may be implemented. The structure, application environment and other aspects of the system of the present invention will be described with reference to fig. 1 and 2. As shown in fig. 1 and 2, the system includes: a make-up information collection module 10, a drop tool information collection module 20, and an information collection and processing module 30. The make-up information acquisition module 10 is arranged at a wellhead and used for acquiring make-up quality information when the current well cementing and completing tool is made up. The running tool information acquisition module 20 is arranged at a wellhead and used for acquiring information including the specification of the current running completion tool to be run and the design sequence of the tool in a preset completion construction operation sequence. The information collecting and processing module 30 is connected to the make-up information collecting module 10 and the running tool information collecting module 20, respectively, and is configured to obtain make-up quality information, tool specifications, and design sequence information for a current tool, on one hand, whether a make-up effect of the current tool is qualified according to the make-up quality information, and on the other hand, according to the current tool specifications and design sequence information, the accuracy of the type and specification of the current running tool (i.e., whether a wrong tool is run, that is, whether the type and specification of the current running tool are consistent with a tool that should be currently run in a preset solid well completion construction operation sequence) is detected, and after all detections for the current solid well completion tool are qualified, the current solid well completion tool is conveyed to a corresponding downhole position.
It should be noted that before the completion operation is performed, the string required for the completion operation of the current well to be constructed needs to be designed in advance. Specifically, the structure of the string (including at least the types of tools required to form the string, the number of each type of tool, the connection sequence of each type of tool, etc.), and the running construction process of the string (including at least the sequence in which one tool should be run at a time and the type of tool corresponding to the tool) need to be designed. Thus, each time a completion tool is run in, not only the results of the make-up operation need to be checked for the current tool, but also the specifications of the current tool need to be verified. It is further desirable to have a pre-designed completion construction sequence stored in the system of the present invention, wherein the completion construction sequence comprises: the design sequence (i.e. the run-in sequence number, for example: when the run-in work of the whole designed pipe string is completed, the design needs to run in 10 fixed completion tools, and 1 tool should be run in each time, the design sequence refers to the sequence number of the current run-in tool which is the number of the tool to be run in the whole pipe string), and the tool specification of the current to-be-run-in tool corresponding to each run-in fixed completion tool (wherein, the tool specification includes information such as the size, the material, the type, and the required make-up torque of the tool of the size type).
Specifically, first, the attaching information collecting module 10 will be explained. Referring to fig. 1 and 2, the upper port information collection module 10 includes: a camera 11 and a button-up quality information collecting unit 12 connected to each other. In practice, a make-up operation using hydraulic tong 103 is required to be run downhole to complete the string of completion tubulars before setting downhole the completion tool 102 currently to be run downhole. The make-up quality information collection unit 12 is connected to the hydraulic tong 103, and is configured to collect make-up torque provided by the hydraulic tong 103 when the hydraulic tong 103 makes a make-up operation on the current completion tool 102 to be set. The camera 11 is then placed at a tool make-up location proximate to the surface wellhead such that the camera 11 is used to photograph the make-up completion at the end of the make-up operation performed by the current completion tool 102 at the hydraulic tong 103. Further, the make-up quality information collection unit 12 is further configured to collect make-up completion pictures, which are acquired by the camera 11 and are specific to the current well cementing and completion tool 102 to be run in, time-stamp the make-up torque and the make-up completion pictures received in sequence, respectively, and then store the two kinds of information in a storage area in the make-up quality information collection unit 12. In this way, the hydraulic tong 103 acquires the make-up torque and make-up completion picture of the current make-up operation during and after the make-up operation of the current solid well completion tool 102 to be run, so that the make-up torque and make-up completion of the current solid well completion tool 102 are detected by using the two information, and the problems about make-up quality such as inaccurate make-up torque and improper make-up are discovered.
Next, the drop tool information collection module 20 will be explained. Referring to fig. 1 and 2, the upper port information collection module 10 includes: a tool label 21, a label detector 22, and a tool information collecting unit 23. Before the completion tool 102 to be lowered into the wellhead (before the make-up operation is performed), the lowering sequence (design sequence) and tool specification information designed by the current completion tool are written into the tool tag 21 according to a construction design scheme (namely a preset completion construction sequence), the tool tag 21 is mounted on the body of the completion tool 102 to be lowered in an adhering or riveting manner, and further, the tag detector 22 is mounted on the periphery of the overflow prevention pipe 104 at the wellhead in advance.
In an embodiment of the present invention, the tool tag 21 is preferably an RFID tag, and the tool tag 21 is mounted on the body of the completion tool 102 to be run in, and correspondingly, the tag detector 22 is preferably an RFID detection device mounted downhole at the anti-spill pipe 104 immediately adjacent the wellhead. Further, to allow the current completion tool 102 to pass through the anti-flood pipe 104, the tag detector 22 may successfully read the information on the tool tag 21 regardless of the orientation in which the tool tag 21 is installed on the body of the current completion tool 102. Preferably, the tag detector 22 is mounted within a detector housing (not shown) that is mounted around the periphery of the flash pipe 104 at the wellhead, and the tag detector 22 is circumferentially disposed within the detector housing. Thus, the label detector 22 in the present embodiment is surrounded around the periphery of the anti-spill pipe 104 by the detector housing, and specifically, the effective detection portion of the label detector 22 is surrounded around the periphery of the anti-spill pipe 104. RFID internet of things radio frequency technology is utilized as the present solid completion tool 102 is run into and through the anti-spill pipe 104 where the tag detector 22 is located so that the tag detector 22 can successfully read the information in the tool tag 21 on the present tool. Specifically, the tool tag 21 is used to store tool specifications and design sequence information for the current completion tool 102. The tag detector 22 is used to read information within the tool tag 21 as the previous completion tool 102 is run in and through the anti-spill pipe. The tool information collection unit 23 is connected to the tag detector 22, and is configured to receive and identify the information read by the tag detector 22, so as to obtain the tool specification and design sequence information for the currently running completion tool 102, and then time stamp and store the information in the storage area in the tool information collection unit 23. In this way, after the hydraulic tong 103 finishes the make-up operation process on the current well cementing and completion tool 102 to be run, in the initial stage of running the current tool 102 (the stage that the current well cementing and completion tool is not completely run and the subsequent well cementing and completion tool is not run), the running tool information acquisition module 20 acquires the basic information of the running tool in the current initial stage of running, so as to detect the accuracy of the current well cementing and completion tool 102 by using the information such as the design sequence, the tool size, the material, the tool type and the like in the basic information, and find the problems about the accuracy of the running tool such as the wrong running and the missing running of the well cementing and completion tool in time.
Further, in the embodiment of the present invention, the tool information collecting unit 23 and the fastening quality information collecting unit 12 are integrated into the data collector 101. Wherein, data collection station 101 still includes: the information aggregating unit 201. Referring to fig. 1 and 2, the information totaling unit 201 is connected to the above-described tool information collecting unit 23 and the fastening quality information collecting unit 12, respectively. The information summarizing unit 201 is configured to sequentially receive the make-up torque in the make-up quality information, the make-up completion degree picture in the make-up quality information, and the tool specification and design sequence information for the current solid completion tool 102 to be made up, determine information with similar acquisition time as information for the same solid completion tool 102 to be made up, and forward the information to the information collecting and processing module 30 for detection and monitoring.
Further, since the duration of the whole process of running one kind of fixed completion tool 102 every time (from make-up to run downhole) is much longer than the duration from the start of make-up operation to the initial stage of running the tool for the same kind of fixed completion tool 102, when determining the information of the same to-be-run fixed completion tool 102, it is necessary to determine the information of which the time interval between the receipt of several different information (make-up torque, make-up completion level picture, and tool specification and design sequence information) is within the information collection time threshold range as the information for the same to-be-run fixed completion tool 102 according to the collection time marked by the information by using a preset information collection time threshold. The information collection time threshold may be determined according to a duration of completing each running of one type of fixed completion tool 102 and a duration of starting the make-up operation to the initial stage of running the tool for the same type of fixed completion tool 102.
Next, the information collection and processing module 30 will be explained. Referring to fig. 1 and 2, an information collection and processing module 30. Wherein the information collection and processing module 30 is integrated with the upper computer 105, and the upper computer 105 is disposed in the wellsite monitoring room or driller's house. Specifically, the information collecting and processing module 30 in the upper computer 105 is first configured to fuse the received make-up torque, make-up completion level picture, and tool specification and design sequence information for the current completion tool 102, and to simultaneously display them on the upper computer display screen. Then, the information collecting and processing module 30 is used for respectively performing the making-up effect detection and the running-in tool accuracy detection according to the making-up quality information, the tool specification and the design sequence information, and generating a corresponding warning prompt signal if one or more of the making-up quality information, the tool specification and the design sequence information are unqualified. Then, the information collecting and processing module 30 is configured to locally respond to the warning prompt signal, respectively display the result of detecting the make-up effect and the result of detecting the accuracy of the drop tool on the display screen of the upper computer, and transmit the currently generated warning prompt signal to the remote server 40, which will be described below, so as to perform warning prompt on the construction site and the remote monitoring platform.
Further, in the above-mentioned make-up effect detection process, the information collecting and processing module 30 is configured to obtain a make-up torque required by a current solid-well completion tool to be put in from a solid-well completion construction operation sequence, determine whether the current make-up torque matches the make-up torque required by the current solid-well completion tool to be put in according to the make-up torque in the make-up quality information, and identify whether the current make-up completion picture contains a thread feature that represents that make-up between the pin and the box is not in place, and if the make-up torque matches and the thread feature is not contained, it indicates that the current make-up effect detection is qualified (i.e. the make-up torque detection result is in place and the make-up completion detection result is also qualified), thereby effectively detecting errors such as inaccurate make-up torque and non-in-place construction operation. In addition, if the result of the torque-on-thread detection is wrong and/or the result of the completion of the thread-on-thread detection is wrong, the result of the current thread-on-thread effect detection is unqualified, wherein the unqualified information contains unqualified reason information (including the fact that the torque-on-thread detection is wrong and/or the completion of the thread-on-thread detection is wrong). In the process of detecting the screwing completion degree, key region features including screwing male buckle features, screwing female buckle features and thread features between the male buckle and the female buckle are extracted from a current screwing completion degree picture, whether the thread features between the male buckle and the female buckle are extracted or not is detected, and if the features are not extracted, the current screwing completion degree detection result is determined to be accurate; otherwise, it is false.
Further, in the tool setting accuracy detection process, the information collecting and processing module 30 is configured to obtain an actual setting sequence number of a current tool to be set (the actual setting sequence number is different from a design sequence, and refers to a sequence in which the tool to be set is actually set in the whole construction implementation process in an actual construction process), retrieve tool specification information of the current tool to be set, which is consistent with the actual setting sequence number, and a corresponding design sequence from the solid-well completion construction operation sequence, compare the retrieved information with the currently obtained tool specification and design sequence information, and determine that the current tool setting accuracy detection result is qualified after all comparisons are qualified; otherwise, the product is not qualified. Specifically, whether the currently acquired tool specification and design sequence information are matched with sub items such as the type, material, size and design sequence of the currently-running solid well completion tool needs to be judged respectively, if all the information are matched, the detection result of the accuracy of the currently-running tool is qualified, and the fault and missing fault of the field construction operation are effectively detected. In addition, if one or more sub-items are not matched, the accuracy detection result of the currently-run tool is indicated to be unqualified, wherein the unqualified information contains unqualified reason information (including error in tool type, error in tool size, error in material quality, error in tool size and/or error in tool design sequence).
Further, the information collecting and processing module 30 is configured to generate a corresponding warning prompt signal containing failure information for local response when one or two of the above-mentioned items are failed in the above-mentioned buckling effect detection and/or the drop tool accuracy detection.

Next, the make-up quality information collecting unit 12 collects the make-up completion degree picture, thereby detecting the make-up torque and make-up completion degree of the current solid completion tool 102 using the information, and finding problems about the make-up quality such as inaccurate make-up torque and inadequate make-up.
Further, in step S320, first, information within tool tag 21 installed on current completion tool 102 is read as current completion tool 102 is run in and through anti-flood pipe 104 using tag detector 22. The tool tag 21 stores tool specifications and design sequence information of the current completion tool. The tool information collection unit 23 then receives and identifies the information read by the tag detector 22 to obtain tool specification and design sequence information, which can be used to test the accuracy of the current completion tool 102 and to discover problems with the accuracy of running tools such as a faulty completion tool, a missing completion tool, etc.
In addition, the method of the invention also comprises a step S340, in the step S340, the obtained buckling quality information, the tool specification and the design sequence information are fused and displayed on a display screen of an upper computer, then buckling effect detection and tool descending accuracy detection are respectively carried out according to the buckling quality information, the tool specification and the design sequence information, if one or more of the buckling quality information, the tool specification and the design sequence information are unqualified, a corresponding warning prompt signal is generated, and the signal is transmitted to the remote server 40 to carry out alarm prompt on the construction site and the remote monitoring platform.
At this time, the remote server 40 obtains real-time monitoring information including the make-up quality information, tool specification and design sequence information, make-up effect detection result and running tool accurate detection result for the current solid completion tool 102, so as to facilitate the remote staff to monitor the make-up and running tool running job site conditions in real time.
In view of the foregoing, the present invention relates to a system and method for monitoring make-up and run-in operations of a completion tool. The invention can detect the accuracy of the tool set in the wellhead in real time, compare the actual tool set sequence with the designed pipe string sequence, find the tool set error and missing in time, and give an alarm to the site and the first place. The invention can also collect the make-up torque of the hydraulic tong, and store the make-up result of each time in a video photographing mode, thereby realizing real-time monitoring of the make-up operation of the pipe string, avoiding the occurrence of tripping accidents caused by inaccurate make-up torque, and simultaneously providing recording data for tracing the reasons of the accidents in the future. And finally, the two sets of monitoring information of tool setting and pipe string buckling are remotely transmitted to a monitoring platform of the first party in real time, so that the first party can accurately monitor the site construction in real time.
