Description

Technical Field

[0001] The invention relates to the technical field of offshore oil drilling rigs, in particular to a special combined debugging tool for offshore oil drilling rigs and a debugging method thereof. Background Art

[0002] With the rapid development of the global oil industry, offshore oil drilling and production activities are undergoing profound changes from shallow water to deep water, from normal temperature and pressure to high temperature and high pressure, and from simple wellbore trajectory to complex wellbore trajectory. This transformation has not only significantly increased the difficulty of drilling and production operations, but also brought higher risks and costs. In particular, offshore oil production has increasingly stringent requirements for drilling rigs, which not only requires the continuous improvement of the configuration level of drilling rigs, but also emphasizes the high professionalism of operators and the good running-in state of equipment during construction. Usually, the installation time of offshore drilling rigs is tight. In order to ensure the smooth joint commissioning and on-time production, the efficiency and accuracy of the commissioning process are crucial. However, there is a common problem in traditional drilling rig joint commissioning operations: the lack of torque display. This problem has occurred in major sea areas around the world, and no effective solution has been found so far.

[0003] In recent years, with the continuous growth of global energy demand, the proven reserves of traditional energy such as onshore oil and natural gas have gradually decreased, and the difficulty of mining has increased, resulting in the production of onshore oil resources being unable to meet market demand. Therefore, people have begun to turn their attention to the ocean to seek new sources of energy. With the development of offshore oil fields and the discovery of a large amount of oil and gas, the number of drilling ships and modular drilling rigs has continued to increase, and the number of drilling rig joint commissioning operations has also increased. However, the existing drilling rig commissioning content and reference data are obviously insufficient, especially the problem of being unable to simulate torque during traditional commissioning, which seriously restricts the accuracy and effectiveness of commissioning operations.

[0004] The lack of torque has a number of adverse effects on rig commissioning operations: first, it reduces the reliability and usability of commissioning operation data; second, due to the inability to provide torque data, the safety and efficiency of subsequent operations cannot be guaranteed, which in turn increases non-productive time, increases production costs, and reduces economic benefits; finally, torque is also an indirect reflection of key indicators such as wellbore cleanliness, wellbore friction, and wellbore stability. Its lack makes it impossible for commissioning operations to fully evaluate the wellbore condition. Summary of the invention

[0005] The purpose of the present invention is to provide a special joint debugging tool and a debugging method for an offshore oil drilling rig in order to solve at least one of the above technical problems.

[0056] Embodiment 3

[0057] Figure 3 The following is a flow chart of a debugging method for a special joint debugging tool for offshore oil drilling rigs according to an embodiment of the present invention. Figure 1-3 As shown, according to one embodiment of the present invention, a method for debugging a special joint debugging tool for an offshore oil drilling rig is applied to any special joint debugging tool for an offshore oil drilling rig of the present invention, and the method comprises the following steps:

[0058] Step S102, selecting the punching and drilling tool body 1;

[0059] Step S104, selecting the number and shape of the torque paddles 3 according to the operation requirements, and surrounding and welding one end of the torque paddle 3 to the outer wall of the punching and drilling tool body 1;

[0060] Step S106, welding the other end of the torque paddle 3 to the inner wall of the annular outer enclosure 2;

[0061] Step S108 , selecting the adjustable nozzle 4 according to the operation requirements, and screwing the adjustable nozzle 4 to the top of the drilling tool body 1 .

[0062] In this embodiment, the debugging method of the special joint debugging tool for offshore oil drilling rigs first needs to select a suitable drilling tool body 1 according to the needs of the on-site drill pipe, and equip it with a corresponding variable buckle joint and drill pipe for connection. Then, according to the specific operation requirements, select the torque paddles 3 of an appropriate number and shape, one end of which will surround and weld to the outer wall of the drilling tool body 1 to ensure a stable connection. Then, the other end of the torque paddle 3 is welded to the inner wall of the annular external enclosure 2 to form a complete frame structure.

[0063] In view of the problem of lack of torque, the main parameter, in the debugging process of traditional seawater drilling rigs, a joint debugging tool with a simple structure and easy use is designed in this embodiment. The tool integrates key components such as the drilling tool body 1, the external enclosure 2, the torque paddle 3 and the adjustable nozzle 4. During the debugging process, the torque paddle 3 generates torque through the friction with the seawater, and the external enclosure 2 plays the role of simulating the well wall and protecting the torque paddle. At the same time, the design of the adjustable nozzle 4 makes it possible to flexibly adjust the water outlet cross-sectional area according to the operation requirements, so as to achieve different pump pressure effects under the same displacement, thereby improving the operation efficiency and adaptability. In addition, the tool can also quickly provide a reference for the torque of the drilling rig debugging operation, thereby ensuring the reference, reliability and usability of the drilling rig debugging operation, further promoting the development of the joint debugging process of offshore oil drilling rigs, and improving the safety and efficiency of on-site drilling and completion operations.

[0064] The present invention realizes accurate reference of torque during debugging by integrating key components such as the drilling tool body, external enclosure, torque paddle and adjustable nozzle. Meanwhile, the design of the adjustable nozzle improves operation efficiency and adaptability, which not only solves the problem of lack of torque parameters in traditional debugging, but also promotes the development of joint debugging technology of offshore oil drilling rigs and improves the safety and efficiency of drilling and completion operations.

[0065] Embodiment 4

[0066] like Figure 1-3 As shown, according to one embodiment of the present invention, a method for debugging a special joint debugging tool for an offshore oil drilling rig is applied to any special joint debugging tool for an offshore oil drilling rig of the present invention, and the specific method is as follows:

[0067] According to the drill pipe size and working conditions of the on-site drilling rig debugging operation, select the corresponding size of the matching joint, select the appropriate size of the punch drill body 1 and the torque cross paddle 3, and cooperate with the drilling rig to perform debugging operations to obtain reliable reference data. The operation steps are as follows:

[0068] (1) According to the drill pipe size and working condition requirements of the on-site drilling rig commissioning operation, the punching tool body 1 and the torque paddle 3 size suitable for the matching joint are selected and the tool is assembled;

[0069] (2) Check the size and buckling degree of the adjustable water hole 4;

[0070] (3) The make-up torque of this tool is made according to the design standard;

[0071] (4) Draw a diagram of the salvage tools and start the pump on the ground to conduct a circulation test before going down the well;

[0072] (5) During the drilling rig debugging process, the speed and displacement are gradually increased, and the relationship between torque and drilling speed is recorded.

[0073] As the output of onshore oil fields gradually decreases and dries up, the water content of many large oil fields gradually increases. The oil industry is gradually moving into the sea, and the number of drilling ships and module drilling rigs is gradually increasing. According to relevant regulations, the commissioning of drilling rigs is increasing day by day, and the reference, reliability and usability of the drilling rig commissioning process and data are gradually optimized. The present invention aims to solve the key problem of the lack of torque parameters in the debugging process of traditional seawater drilling rigs. By designing a special joint debugging tool for offshore oil drilling rigs with a simple structure and easy operation, the tool can quickly provide accurate torque references for drilling rig commissioning operations, thereby ensuring the reference, reliability and practicality of drilling rig commissioning operations, and further improving the safety and efficiency of on-site drilling and completion operations.

[0074] Aiming at the key problem of lack of torque parameters in joint debugging of offshore drilling rigs, the present invention designs a special joint debugging tool for offshore oil drilling rigs and a debugging method thereof. The tool can generate and measure torque during the debugging process through innovative structural design, thus filling the gap in this important parameter of traditional debugging methods. The use of this tool for joint debugging can not only simulate the torque load during normal drilling operations and back-marking operations, but also provide high-displacement, high-pump pressure, and high-torque superimposed load joint debugging, highly restoring the rig load conditions during actual drilling operations.

[0075] The debugging method of the joint debugging tool for offshore oil drilling rigs of the present invention significantly improves the accuracy and practicality of the joint debugging operation, and provides strong data support for the performance evaluation of the drilling rig and the safe and efficient operation in the later stage. Through accurate joint debugging in the early stage, problems such as abnormal top drive function caused by torque load can be effectively avoided, non-production time can be reduced, production costs can be reduced, and economic benefits can be improved.
