Description

Technical Field

[0001] The present invention belongs to the field of installation construction of non-metallic pipelines in oil and gas fields, and particularly relates to a field automatic threading device and method for large-diameter high-pressure fiberglass pipe lines. Background Technique

[0002] With the continuous acceleration of oil and gas exploration and development efforts, the accelerated development of deep and unconventional oil and gas resources, and the continuous promotion of production increase in old oil and gas fields, the composition of oil and gas produced at the wellhead is more complex and the operating conditions are more demanding. The surface gathering and transportation system faces severe corrosion challenges. Steel pipelines are widely used in oil and gas field surface pipelines due to their high mechanical strength, low initial investment cost, and convenient use and maintenance. However, due to their poor corrosion resistance, corrosion failure problems occur frequently, greatly increasing the operating costs and safety risks of oil and gas field enterprises. Fiberglass pipe lines have become the best solution to replace steel pipelines on the surface of oil and gas fields to solve corrosion problems due to their excellent corrosion resistance, low hydraulic friction coefficient, wear resistance, and the ability to delay wax and scale formation.

[0003] The existing connection forms of fiberglass pipe lines include threaded connection, flange connection, bonding connection, socket + O-ring seal connection, etc. In particular, threaded connection is the most widely used due to its high mechanical strength and reliable connection. During on-site threading construction, the manual + pipe wrench method is generally used. This threading method requires multiple people to cooperate and is time-consuming. Especially for the threading operation of large-diameter high-pressure (above 3.45 MPa) fiberglass pipe lines, due to the larger threading torque of coarse-threaded threads and the greater self-weight of large-diameter high-pressure pipes, the difficulty of manual threading increases significantly, the threading efficiency drops severely, and in general field conditions, its threading efficiency is even lower and the threading quality cannot be guaranteed.

Correspondingly, in addition to the base member 204 and the roller members 205 at the movable base 203, there is also a hydraulic cylinder for driving the base member 204 to lift (in the direction perpendicular to the top surface of the second support platform 102) to adjust the height position of the movable base 203.

[0057] Referring to Figure 1 , the clamping assembly 300 includes a first clamping structure 301 and a second clamping structure 302, and at least one of the first clamping structure 301 and the second clamping structure 302 is configured to linearly move along the length direction of the second support platform 102. In some examples, referring to Figure 1 , the first clamping structure 301 is fixedly connected to the first support platform 101 through a first column 400. The second clamping structure 302 is connected to the first support platform 101 through a second column 401. A first slider 403 is provided at the first end 102a where the second column 401 is connected to the first support platform 101.

[0058] Referring to Figures 1 - 3, Continuing to describe the composition of the clamping assembly 300, both the first clamping structure 301 and the second clamping structure 302 include a ring structure 303 and a clamping structure 306. Among them, the ring structure 303 has a protective layer 304 and a skeleton layer 305 arranged in sequence from the inside to the outside. The protective layer 304 is made of a material with certain elasticity (such as rubber) and is configured as the contact layer with the glass fiber reinforced plastic pipe and can protect the glass fiber reinforced plastic pipe in direct contact with it. The skeleton layer 305 is made of a rigid metal material (such as steel). Further, the ring structure 303 includes a first ring portion 300a and a second ring portion 303b. Both the first ring portion 300a and the second ring portion 303b are configured as arc-shaped sleeves, and one end (subsequently referred to as the fixed end) of the first ring portion 300a and the second ring portion 303b is rotatably connected (such as hinged), and the other end (subsequently referred to as the free end) is detachably connected (such as snap-connected). When in use, after the first ring portion 300a and the second ring portion 303b wrap the glass fiber reinforced plastic pipe, the free ends of the first ring portion 300a and the second ring portion 303b are connected to circumferentially lock the glass fiber reinforced plastic pipe.

Among them, the fixture structure includes a first fixture portion 307 and a second fixture portion 308 spaced apart in the width direction of the second support table 102. The first fixture portion 307 and the second fixture portion 308 are installed by being connected to columns (the first column 400 and the second column 401) and the second support table 102, and at least one of the first fixture portion 307 and the second fixture portion 308 is configured to linearly move along the width direction of the second support table 102 body. Correspondingly, the above contact structure is assembled on the first fixture portion 307 and / or the second fixture portion 308. By moving the first fixture portion 307 and / or the second fixture portion 308, the contact structure contacts the ring structure 303 and clamps it, thereby realizing the clamping of the glass fiber reinforced plastic pipe. Refer to Figure 2 and 3 , In some embodiments, the second fixture portion 308 is configured as a support column connected to the second support table 102, and a second slider 404 capable of sliding along the length direction of the second support table 102 is provided at the connection position between the second support column and the second support table 102 to cooperate with the sliding of the first slider 403 on the first support table 101 body to realize the movement of the second clamping structure 302. Correspondingly, the first fixture portion 307 is also configured as a columnar structure; Continuing to refer to Figure 2 and 3, the above contact structure includes at least a contact wheel set assembled on the first fixture part 307. The contact wheel set is composed of two support wheel bodies 309 spaced apart on the first fixture part 307, and the distance between the two support wheel bodies 309 constituting the contact wheel set is adjustable, that is, at least one of the two support wheel bodies 309 is configured to be linearly movable along the first fixture part 307 to be suitable for clamping fiberglass pipelines with different diameters. In some embodiments, the above support wheel body 309 is connected to the fixture part (the first fixture part 307 or the second fixture part 308) through a spring 310, and one end of the spring 310 is fixed to the first clamping part by a screw. By changing the installation position of the spring 310, the position of the support wheel body 309 is adjusted, and further the distance between the two support wheel bodies 309 is adjusted. In some embodiments, for the first clamping structure 301, contact wheel sets are provided on both the first fixture part 307 and the second fixture part 308. For the second clamping structure 302, a contact wheel set is only provided on the first fixture part 307.

[0060] Referring to Figure 2 and 3 , continue to describe the clamping assembly 300. The above first clamping structure 301 and second clamping structure 302 further include a sleeve member 311 and a connecting column body 312. The sleeve member 311 is assembled at one end of the column body (the first column body 400 and the second column body 401) and extends along the width direction of the second support table 102. One end of the second fixture part 308 away from the second support table 102 is connected to the sleeve member 311. Correspondingly, one end of the connecting column body 312 is connected to the first fixture part 307, and the other end extends along the width direction of the second support table 102 body into the sleeve member 311 and is configured to be able to slide in the sleeve member 311. By the movement of the connecting column body 312 in the sleeve member 311, the linear movement of the second fixture part 308 in the width direction of the second support table 102 is realized. In some embodiments, the above first clamping structure 301 and second clamping structure 302 further include a runner member 313 and a screw member 314. The runner member 313 is assembled on the outer side of the sleeve member 311 and is configured to be able to rotate around its own axis. Correspondingly, the screw member 314 is configured to extend along the width direction of the second support table 102, and one end of the screw member 314 passes through the runner member 313 and is connected to the connecting column body 312. At the same time, the runner member 313 and the screw member 314 are configured to be in threaded connection. By applying a rotational driving force to the runner member 313, the screw member 314 is driven to linearly move in the width direction of the second support table 102, and further drive the connecting column body 312 and the first fixture part 307 to linearly move in the width direction of the second support table 102 to realize the distance adjustment between the first fixture part 307 and the second fixture part 308.

[0061] Referring to Figure 2 and3 , The above-mentioned second clamping structure 302 further includes a rotating assembly 315 configured to drive the male threaded end of the fiberglass pipe to rotate after the second clamping structure 302 clamps the male threaded end of the fiberglass pipe. In some embodiments, the rotating assembly 315 includes a driving member 316, a worm member 317, and a turbine member 318.

Correspondingly, the turbine member 318 is assembled on the second fixture portion 308 of the second clamping structure 302 and meshes with the above-mentioned worm. At the same time, teeth 319 meshing with the turbine are provided on the ring structure 303. When the rotating assembly 315 works, the rotational driving force of the driving member 316 is transmitted to the ring structure 303 through the turbine member 318 and the worm member 317 to drive the ring structure 303 and the fiberglass pipe locked by the ring structure 303 to rotate. Further, the rotating assembly 315 further includes a torque system 320 for controlling the output torque of the driving member 316.

[0063] For connecting the female threaded end of a fiberglass pipe (subsequently referred to as the first pipe 10) and the male threaded end of another fiberglass pipe (subsequently referred to as the second pipe 20).

[0064] S100: Adjust the inclination angle of the second support platform 102 based on the diameters of the first pipe 10 and the second pipe 20;

[0065] S200: Place the first pipe 10 on the first support group 200, adjust the distance between the female threaded end of the first pipe 10 and the ring structure 303 in the first clamping structure 301 to a set distance, and after circumferentially locking the first pipe 10 through the ring structure 303, clamp the first pipe 10 through the clamping structure 306;

[0066] S300: Place the second pipe 20 on the second support group 201, adjust the distance between the male threaded end of the second pipe 20 and the ring structure 303 in the second clamping structure 302 to a set distance, and after circumferentially locking the second pipe 20 through the ring structure 303, clamp the second pipe 20 through the clamping structure 306;

[0067] S400: Under the preset torque condition, control the rotating assembly 315 to drive the second pipeline 20 to rotate to complete the make-up.

[0068] Among them, controlling the rotating assembly 315 to drive the second pipeline 20 to rotate to complete the make-up based on the preset torque includes:

[0069] Under the first torque condition, control the rotating assembly 315 to drive the second pipeline 20 to rotate to complete the first make-up process;

[0070] Under the second torque condition, control the rotating assembly 315 to drive the second pipeline 20 to rotate to complete the second make-up process.

[0071] Among them, clamping the first pipeline 10 through the clamping structure 306 includes:

[0072] Adjust the distance between the two support wheel bodies 309 in the contact wheel group;

[0073] Adjust the distance between the first clamping part 307 and the second spacing part so that the contact wheel group contacts the ring structure 303.

[0074] Specifically, before adjusting the inclination angle of the second support platform 102, it is necessary to drive the make-up device to move along the direction of the medium source of the pipeline through an external vehicle-mounted system. The center line of the second support platform 102 should be basically close to the center line of the trench. At the same time, in step S100, determine the inclination angle α of the loading platform according to the nominal diameter of the fiberglass pipe pipeline, generally 0° to 30°, and the larger the nominal diameter of the fiberglass pipe pipeline, the smaller the inclination angle.

[0075] In step S200, the set distance between the female threaded end of the first pipeline 10 and the ring structure 303 in the first clamping structure 301 is between 100 mm and 300 mm. At the same time, when the clamping structure 306 is working, it is necessary to adjust the contact position between the support wheel body 309 and the ring structure 303 to ensure that the four contact points are symmetrically distributed and the force is evenly distributed. At the same time, when clamping for make-up, the principle is not to slip.

[0076] In step S300, the set distance between the female threaded end of the second pipeline 20 and the ring structure 303 in the second clamping structure 302 is between 100 mm and 300 mm. At the same time, when the clamping structure 306 is working, it is necessary to adjust the contact position between the support wheel body 309 and the ring structure 303. At the same time, when clamping for make-up, the principle is not to slip. Finally, it is necessary to adjust the height of the movable seat body 203 to ensure that the two pipes are aligned. It is required that the radial distance between the upper and lower positions of the outer end face of the male thread of the second pipeline 20 and the inner end face of the female thread of the first pipeline 10 is equal, and the deviation does not exceed 10% of the wall thickness and is less than 2 mm. The maximum deviation of the parallelism at 300 mm from the end face of the male thread joint of the second pipeline 20 is 2 mm.

[0077] In step S400, before the rotating assembly 315 operates, it is necessary to first install a rubber sealing ring and apply lubricating oil to the male thread joint of the second pipeline 20. The minimum torque, maximum torque, and optimal torque are determined according to the torque test. The minimum torque constitutes the above-mentioned first torque, and the optimal torque constitutes the second torque. In the first make-up process, the rotation speed does not exceed 100 r / min, and it is appropriate to make 2 to 3 threads. In the second make-up process, the rotation speed does not exceed 200 r / min and automatically shuts down after reaching the maximum torque.

[0078] Finally, after the make-up is completed, the clamping systems of the first pipeline 10 and the second pipeline 20 are released, and a fully made-up pipe is lowered into the trench. After the device moves forward, another pipe is placed and the make-up is continued according to the above steps. And so on, the make-up is carried out in a cycle.

[0079] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
