Description

Technical Field

[0001] This utility model relates to the field of blowout preventer technology, and in particular to an integrated bridge-jet wellhead device. Background Technology

[0002] In cable logging and perforation operations, the wellhead blowout preventer is installed on the Christmas tree to seal the wellhead with the cable in case of cable accidents such as cable jamming or wire skipping, and to close the wellhead in case of various abnormal accidents. The function of the downhole catcher is first to serve as a warning when the logging instruments and gun strings are raised to the wellhead, and then to protect the logging instruments and gun strings from falling into the well and causing accidents due to various unexpected situations after they have passed through.

[0003] The traditional method involves first connecting the blowout preventer (BOP) above the wellhead, then connecting it to the BOP via a union joint (including a rubber O-ring) under the lower catcher, and finally connecting it to the lower catcher via a union joint (including a rubber O-ring) under the plug-in device. Each component requires hoisting, which not only increases the workload but also raises the operational risks and the risk of leakage due to frequent disassembly and reassembly. Furthermore, because the union nut requires a large axial dimension during installation (limited by the mechanical structure itself), traditional BOP devices suffer from drawbacks such as high height, heavy weight, complex structure, and cumbersome operating procedures.

[0004] Therefore, it is necessary to provide an integrated bridge-shot wellhead device to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides an integrated bridge-jetting wellhead device, which solves the problems of traditional bridge-jetting wellhead devices requiring multiple components to be hoisted and installed in stages, resulting in a cumbersome operation process, a large workload, and the high height of the device and easy impact on sealing due to the connection of the connector.

[0009] Preferably, both the first and second twin-wire connectors include two external threads, a boss partition wall, and two sealing structures. The two external threads are respectively fixedly installed on the top and bottom of the boss partition wall, and the two sealing structures are respectively disposed at one end of the two external threads.

The device comprises a blowout preventer (BOP) cage, a working platform, the BOP, a first double-wire connector, a lower catch, a plug valve, a second double-wire connector, and a plug-in device.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment

[0018] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an integrated bridge-jet wellhead device provided by this utility model; Figure 2 for Figure 1 The diagram shown is a schematic of the blowout preventer cage structure. Figure 3 for Figure 1 The schematic diagram shows the structure of the blowout preventer, the first twin-wire connector, the lower catcher, and the plug valve. Figure 4 for Figure 3 The diagram shows the structure of the first twin-wire connector.

[0019] An integrated bridge-fuse wellhead device includes: a blowout preventer (BOP) cage 1, a working platform 2, a BOP 3, a first double-wire connector 4, a lower catch 5, a stopcock valve 6, a second double-wire connector 7, and a plug-in device 8. The working platform 2 is located on top of the BOP cage 1. The BOP 3 is located on the inner side of the BOP cage 1. The lower catch 5 is located on top of the BOP 3. The plug-in device 8 is located on top of the lower catch 5. The first double-wire connector 4 is located between the lower catch 5 and the BOP 3, and its function is to provide a sealing connection between the BOP 3 and the lower catch 5. The second double-wire connector 7 is located between the lower catch 5 and the plug-in device 8, and its function is to provide a sealing connection between the lower catch 5 and the plug-in device 8. The stopcock valve 6 is installed on the front of the lower catch 5.

[0020] The blowout preventer cage 1 includes a frame 101, a foot pedal 102, four U-shaped slots 103, and two steel plate pressure strips 104. The foot pedal 102 is installed on the front of the frame 101, the four U-shaped slots 103 are all installed on the inner side of the frame 103, and the two steel plate pressure strips 104 are all fixedly installed on the top of the frame 101.

[0021] The four U-shaped slots 103 are respectively disposed at both ends of the front and back of the blowout preventer 3 to limit the side of the blowout preventer 3, and the two steel plate pressure strips 104 are respectively disposed at both ends of the top of the blowout preventer 3 to limit the top of the blowout preventer 3.

[0022] Both the first twin-wire connector 4 and the second twin-wire connector 7 include two external threads 41, a boss isolation wall 42, and two sealing structures 43. The two external threads 41 are respectively fixedly installed on the top and bottom of the boss isolation wall 42, and the two sealing structures 43 are respectively disposed at one end of the two external threads 41.

[0023] The top of the plug-in device 8 is equipped with a lifting connector 9.

[0024] The blowout preventer cage 1 is connected to the blowout preventer 3 by clamping the blowout preventer 3 with a square tube structure having a U-shaped slot 103, and by the steel plate pressure strip 104 on its top and bolts. The lower catcher 5 is connected to the internal thread on the top of the blowout preventer 3 through the first double-threaded connector 4, and the plug-in connector 8 is connected to the internal thread on the top of the lower catcher 5 through the second double-threaded connector 7, forming a whole. First: The blowout preventer cage 1 has a guide U-shaped slot 103 inside. During installation, the blowout preventer 3 is slid into the U-shaped slot 103 of the blowout preventer cage 1 along the guide slot. After it is in place, a steel plate pressure plate 104 is placed on top and then locked to the crossbeam with high-strength bolts to form an integral whole with the cage. Next, screw the lower end of the first double-threaded connector 4 (with sealing rings installed at both ends) into the inner thread at the top of the blowout preventer 3.

[0025] Then screw the inner thread on the lower end face of the lower catcher 5 to the upper end of the first double-thread connector 4 to complete the installation of the lower catcher 5. Then screw the lower end of the second double-wire connector 7 into the top inner wire of the lower catcher 5; Finally, screw the inner thread on the lower end of the plugger 8 onto the upper end of the second double-thread connector 7 to complete the installation of the plugger 8.

[0026] Both ends of the first double-threaded connector 4 and the second double-threaded connector 7 are machined with right-hand external threads, which connect to the internal threads on the upper end face of the blowout preventer 3, the lower end face of the lower catcher 5, and the lower end face of the inserter 8, respectively. The outer sides of both ends of the first double-threaded connector 4 and the second double-threaded connector 7 have sealing groove structures 43, which provide a sealing function after the sealing ring is installed. By rotating the double-threaded connector and the lower catcher 5, a reliable connection and seal between the two can be achieved. Then, the second double-threaded connector is installed into the internal thread on the upper end face of the lower catcher 5. Finally, the inserter 8 is installed into the external thread on the other end of the double-threaded connector and screwed in to lock it. This structure saves the large amount of operating space required by the traditional union nut and integrates this integrated bridge-jetting wellhead device. It does not need to be disassembled during use and only needs to be opened during maintenance. Transportation hoisting, maintenance hoisting, and temporary hoisting operations: Normally, the blowout preventer 3, lower catcher 5, and inserter 8 are integrated into one unit, serving as a single unit for transportation, operation, and storage. Therefore, this integrated wellhead unit is equipped with a dedicated lifting connector 9 for hoisting. When transportation is required, the lifting connector 9 must first be inserted into the flared opening at the top of the integrated wellhead unit. After insertion, connect the hydraulic lines and start the hydraulic system. Operate the hydraulic valves to lock the locking blocks and locking discs of the inserter. Then, disconnect the hydraulic system lines for hoisting. Note: Individual components or parts should only be disassembled for repair or maintenance when the integrated wellhead unit malfunctions. Disassembly is generally unnecessary. See the attached diagram below for details. Figure 1 .

[0027] Operating conditions during wellhead connection operations: The robotic arm of the intelligent integrated work vehicle inserts the upper connector 10 of the special plug-in device 8 at the bottom of the pre-connected blowout preventer string 11 into the guide horn at the top of the integrated bridge-jet wellhead device. After it is in place, the locking block and locking disc on the plug-in device 8 are locked. Then, the robotic arm of the integrated intelligent bridge-jet work system is operated to lift the integrated bridge-jet wellhead device as a whole and insert it into the union at the top of the wellhead flange 12. The union nut is tightened, completing the hoisting and installation of the integrated bridge-jet wellhead device at the wellhead. Note: No additional crane is required for connection to the well, which greatly improves the efficiency of the operation.

[0028] Based on the above-mentioned reconstructed technical solution, the beneficial effects should be fully deepened and quantified; Revolutionary improvement in operational efficiency: Transforming the on-site "serialized" step-by-step installation into an "integrated plug-and-play" overall hoisting, reducing the installation and dismantling time of wellhead equipment in single-well operations; Safety is significantly enhanced: It avoids high-altitude and cross-operations, reduces the frequent movement of personnel up and down the wellhead, and fundamentally reduces safety risks such as falls and collisions; modular integration also reduces well control risks caused by misinstallation or omissions on site; Reduced transportation and warehousing costs: The integrated structure is more compact than the dispersed components, reducing the size and number of transport skids and directly lowering the transportation cost per well; at the same time, standardized modules facilitate warehouse management. In addition, the overall integration reduces the height, thus effectively solving the major problem of height restrictions during transportation.

[0029] Improved reliability: The integrated connection manufactured in the factory has a much higher quality control, sealing and strength reliability than the separate installation under field conditions.

[0030] The working principle of the integrated bridge-jetting wellhead device provided by this utility model is as follows: The blowout preventer 3 and the lower catcher 5 are connected by a first double-threaded connector 4: the bottom external thread 41 of the double-threaded connector is threaded to the top interface of the blowout preventer 3, and the top external thread is threaded to the bottom interface of the lower catcher 5. The boss isolation wall 42 enhances the structural strength and can also tighten and limit the threads on both sides. The sealing structure 43 at both ends (using metal sealing ring + rubber sealing gasket double sealing) ensures that there is no leakage at the connection. Similarly, the lower catcher 5 and the plug-in device 8 are connected by a second double-threaded connector 7, which replaces the traditional union connector and reduces the connection gap. The connected blowout preventer 3 is placed inside the frame 101 of the blowout preventer cage 1. Four U-shaped slots 103 respectively lock the two ends of the front and back of the blowout preventer 3, restricting the horizontal movement of the blowout preventer 3. Two steel plate pressure strips 104 press on the top two ends of the blowout preventer 3, restricting the vertical displacement and ensuring the stability of the blowout preventer during operation. The working platform 2 allows the operator to stand and operate the plug valve 6 (which can control the opening and closing of the wellhead passage during operation). The pedal 102 is a movable pedal that can be flexibly hung in a certain place for temporary tasks, and at the same time, it can facilitate personnel to get on and off the platform. The entire assembly (blowout preventer 3, lower catcher 5, and plugger 8 are integrated) can be hoisted using the lifting joint 9 at the top of the plugger 8, reducing the workload of multiple hoisting operations compared to traditional devices. After hoisting, this integrated bridge-perforation wellhead device can be connected to the flange at the top of the wellhead to carry out cable logging and perforation operations. The lower catcher 5 can prevent logging instruments and gun strings from falling accidentally, and the blowout preventer 3 can seal the wellhead in the event of a cable accident, ensuring operational safety.

[0031] Compared with related technologies, the integrated bridge-jet wellhead device provided by this utility model has the following beneficial effects: The blowout preventer (BOP) cage 1, working platform 2, BOP 3, first double-wire connector 4, lower catcher 5, plug valve 6, second double-wire connector 7, and plug-in device 8 work together to achieve a seamless connection of the BOP 3, lower catcher 5, and plug-in device 8 during bridge-jet wellhead operations. This replaces the traditional union connector, reducing connection gaps and leakage risks. Furthermore, it eliminates the need for multiple hoisting operations of each component, significantly reducing workload and operational risks. This solves the problems of traditional bridge-jet wellhead devices requiring multiple hoisting operations of multiple components, resulting in cumbersome procedures, heavy workloads, and the high height and compromised sealing caused by union connector connections.

[0032] Second Embodiment

[0033] Please refer to the following: Figure 5 Based on the integrated bridge-flying wellhead device provided in the first embodiment of this application, the second embodiment of this application proposes another integrated bridge-flying wellhead device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0034] Specifically, the second embodiment of this application provides an integrated bridge-fuse wellhead device that differs in that the integrated bridge-fuse wellhead device further includes an upper connector 10 for the inserter, a blowout preventer string 11, and a wellhead flange 12. The upper connector 10 for the inserter is installed on the top of the inserter 8, the blowout preventer string 11 is installed on the top of the upper connector 10 for the inserter, and the wellhead flange 12 is installed on the bottom of the blowout preventer 3.

[0036] After the work is completed, disassemble in the opposite direction and then store in the factory warehouse.

[0037] The working principle of the integrated bridge-jetting wellhead device provided by this utility model is as follows: The upper connector 10 of the plug-in device is threaded to the top of the plug-in device 8 and is used to adapt to the installation of the blowout preventer string 11. The blowout preventer string 11 provides a space and channel for the logging cable and the perforating gun string to be pulled out and lowered into the well. The wellhead flange 12 is connected to the bottom of the blowout preventer 3 by tightening the union nut and is connected to the top flange of the production tree by bolts to achieve a stable and sealed connection between the device and the wellhead, ensuring the pressure bearing capacity of the wellhead operation.

[0038] Compared with related technologies, the integrated bridge-jet wellhead device provided by this utility model has the following beneficial effects: The upper connector 10 of the plug-in device, the blowout preventer string 11, and the wellhead flange 12 work together to provide a space and passage for the logging cable and the perforating gun string to be pulled out and lowered into the well during bridge-perforation wellhead operations. The wellhead flange 12 is firmly connected to the top flange of the Christmas tree by bolts, which enhances the sealing and bearing capacity of the device and the wellhead, and is suitable for high-pressure wellhead operation scenarios.

[0039] Third Embodiment

[0040] Please refer to the following: Figure 6 and Figure 7 Based on the integrated bridge-flying wellhead device provided in the first embodiment of this application, the third embodiment of this application proposes another integrated bridge-flying wellhead device. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0041] Specifically, the third embodiment of this application provides an integrated bridge-flying wellhead device that differs in that it further includes multiple mounting components 13. These mounting components 13 are disposed on the top of the blowout preventer cage 1 and the bottom of the working platform 2. Each mounting component 13 includes a mounting nut 131, a mounting bracket 132, a mounting bolt 133, and a base plate 134. The base plate 134 is disposed at the bottom of the blowout preventer cage 1. The mounting bracket 132 is disposed on the outer side of the working platform 2. The mounting bolt 133 passes through the top of the mounting bracket 132 and extends to the bottom of the base plate 134. The mounting nut 131 is threaded onto the outer side of the mounting bolt 133 and is located at the bottom of the base plate 134.

[0042] The working principle of the integrated bridge-jetting wellhead device provided by this utility model is as follows: The base plate 134 of the mounting assembly 13 is attached to the blowout preventer cage 1, and the mounting bracket 132 is attached to the outer side of the working platform 2. The mounting bolt 133 is passed from the top of the mounting bracket 132 to the bottom of the base plate 134. The mounting nut 131 is tightened so that the mounting bracket 132 and the base plate 134 cooperate to clamp the working platform 2 and the blowout preventer cage 1, thereby enhancing the fixing strength between the blowout preventer cage 1 and the working platform 2 and preventing the device from shaking during high-pressure operation. Multiple installation components 13 are evenly distributed (e.g., 4, located at the four corners of the work platform 2) to ensure uniform force distribution.

[0043] Compared with related technologies, the integrated bridge-jet wellhead device provided by this utility model has the following beneficial effects: With the installation component 13 in place, during bridge-jet wellhead operations, the installation bolt 133 passes through the installation frame 132 and the base plate 134, and the installation nut 131 is tightened to make the two work together to clamp the working platform 2 and the blowout preventer cage 1. Multiple installation components 13 are evenly distributed, which greatly enhances the fixing strength of the blowout preventer cage 1 and the working platform 2, and avoids the device shaking and shifting during high-pressure operations.
