Description

Technical Field

[0001] The present invention belongs to the technical field of oil drilling, and particularly relates to a simulation device for automatic lifting of drill pipes. Background Art

[0002] Oil and natural gas are important energy sources. After confirming the location of oil and natural gas, it is necessary to connect with them through drilling, and then extraction can be carried out. Therefore, drilling is one of the important steps in the extraction of oil and natural gas. During the drilling process, it is necessary to lift the drill pipe (drilling tool) from the ground to the wellhead by a drilling rig, then straighten the drill pipe, also known as a stand, and finally connect the drill pipes together by the drilling rig. This process is called "lifting and making up the drill pipe". The lifting and making up of the drill pipe is related to the safety and efficiency of oil and gas well operations. An incorrect lifting process may lead to accidents, causing casualties and equipment damage, thus affecting the progress and efficiency of the entire drilling operation.

[0003] Currently, the completion of the lifting and making up of the drill pipe mainly relies on manual operation. When the drill pipes are connected and the threads are aligned, the operator needs to manually adjust the position of the drill pipe to achieve the initial meshing of the threads. This operation often results in misaligned or offset threads due to manual visual errors and operation delays, thereby causing abnormal wear or even failure of the threads, and situations such as sticking of the drill pipe and equipment abnormalities. To facilitate the process of lifting and making up the drill pipe, it is necessary to design a simulation device for automatic lifting of the drill pipe based on intelligent automatic control, which is used to simulate the operation of lifting and making up the drill pipe. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background art, and provide a simulation device for automatic lifting of drill pipes, which can automatically complete the process of lifting and making up the drill pipe, can not only demonstrate this operation, but also provide reference data for the intelligent construction of oil and gas wells.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] A simulation device for automatic lifting of drill pipes includes a base and a support frame arranged on the base. There is a vertically installed drill pipe passage left between the support frame and the base. Above the support frame, there is a drill pipe guiding device for clamping the drill pipe and performing stand operations. Between the drill pipe guiding device and the support frame, there is a power tong assembly for connecting adjacent parts of two drill pipes. Inside the support frame below the power tong assembly, there are two sets of collar connectors arranged up and down, which are used to position the drill pipe located below when the power tong assembly connects the drill pipes. At the bottom of the support frame, there is a power slip for clamping the lower drill pipe. On the support frame, there are multiple electric push rod assemblies vertically installed for adjusting the distance from the base.

[0007] The drill pipe guiding device includes a lifting disc, a telescopic support, drill pipe clamping jaws, a rudder servo and an electric push rod. A through hole for the drill pipe to pass through is provided in the middle of the lifting disc. The telescopic support is in a frame shape, and two telescopic rods with extendable ends are provided on the telescopic support. Both telescopic rods are rotatably connected to the surface of the lifting disc on one side of the through hole through bearing seats. The top of the telescopic support is connected to the drill pipe clamping jaws. A rudder servo for adjusting the clamping direction of the drill pipe clamping jaws is installed on the telescopic support. There are two electric push rods. The two electric push rods are hinged to the surface of the lifting disc on the other side of the through hole through push rod supports, and the extendable ends of the two electric push rods are connected to the telescopic support. The telescopic support, the electric push rods and the lifting disc are distributed in a triangle. An angle adjustment servo for controlling the working angle of the electric push rods is installed on the lifting disc on one side of the push rod support.

[0008] The drill pipe clamping jaws include a mechanical jaw bottom plate, clamping finger assemblies symmetrically arranged on the bottom plate, and a clamping finger servo for driving the clamping finger assemblies to close or expand. The clamping finger assemblies include clamping jaw force arms, clamping plates and clamping jaw link rods. The clamping jaw force arms and the clamping plates are sequentially hinged. The clamping jaw force arms are rotatably installed on one side of the mechanical jaw bottom plate. One end of the clamping jaw link rod is hinged to the middle of the clamping plate, and the other end is connected to the mechanical jaw bottom plate. The clamping jaw force arms, the clamping plates, the clamping jaw link rods and the mechanical jaw bottom plate form a four-claw link structure. Semi-circular teeth that mesh with each other are machined on the opposite clamping jaw force arms of the two clamping finger assemblies.

[0009] The power tong assembly includes a power tong bottom plate, a lifting push rod, a guide post, a chuck support ring, a rotating core, a power tong motor and chuck jaws. The power tong bottom plate is parallel to the lifting disc. A lifting push rod for driving the lifting disc to rise and fall and a guide post for keeping parallel to the lifting disc are installed on the power tong bottom plate. A turntable bearing is installed in the middle of the power tong bottom plate. The rotating core is installed on the turntable bearing and can rotate on the power tong bottom plate through the turntable bearing. An external gear ring is installed at the bottom of the rotating core. The power tong motor is installed on the power tong bottom plate outside the rotating core. The output shaft of the power tong motor vertically passes through the power tong bottom plate and then installs a main gear that meshes with the external gear ring. The chuck support ring is slidably sleeved on the outer wall of the rotating core up and down. A connecting rod that can move following the lifting disc is installed on the surface of the chuck support ring. A limit chute for cooperating with the connecting rod is provided on the through hole. A plurality of chuck jaws distributed radially are installed in the rotating core. Sliders passing through the rotating core are machined on the outer walls of the chuck jaws. Grooves for the sliders to slide in and out are machined on the rotating core. Horizontal strip-shaped grooves are machined on the rotating core on both sides of the groove. Limit shafts placed in the strip-shaped grooves are installed on the sliders. A chuck link rod hinged to the limit shaft is rotatably installed on the bottom surface of the chuck support ring. When the chuck support ring slides up and down along the rotating core, it drives a plurality of chuck jaws to simultaneously close or simultaneously open in the grooves. The chuck support ring, the chuck link rod, the slider, the chuck jaws and the strip-shaped grooves form a crank-slider mechanism.

[0010] A lead screw module for controlling the lifting of the power tong bottom plate is also installed on the support frame.

[0011] The collar tool includes a cross beam, a slide support, a bidirectional lead screw, a nut seat, a caliper and a polished rod. The two cross beams are parallel, and a slide support is installed on each cross beam. The bidirectional lead screw is rotatably installed on one of the slide supports through a bearing support, and the polished rod is installed on the other slide support. The bidirectional lead screw and the polished rod are parallel. Two nut seats are installed on the bidirectional lead screw, and a sliding sleeve opposite to the two nut seats is installed on the polished rod. Two calipers are symmetrically installed on the two nut seats and the sliding sleeve along the central axis of the drill pipe.

[0012] The power slip includes a support seat, a driving motor, a driving gear, a driven gear, a double-headed lead screw, a guide rod and a slip body. The support seat is fixed at the bottom of the support frame, and a driving motor is installed on the support seat. The driving gear is installed on the output shaft of the driving motor. The driven gear is installed on one side of the driving gear and meshes with the driving gear. The driven gear is coaxially connected with a double-headed lead screw. The two slip bodies are respectively threadedly connected to both ends of the double-headed lead screw. The guide rod is parallelly installed on the support seat on one side of the double-headed lead screw. Both ends of the guide rod penetrate through the two slip bodies and support the slip bodies to clamp or loosen the drill pipe on the support seat.

[0013] Universal wheels are installed on the base.

[0014] The beneficial effects of the drill pipe automatic lifting simulation device provided by the present invention are as follows:

[0030] As Figures 1 to 9 Shown in the figure, the drill pipe automatic lifting simulation device provided in this embodiment includes a base 1 and a support frame 2 arranged on the base 1. The support frame 2 is used to install the simulation device. The base 1 serves as a support component to increase the ground clearance of the support frame 2. Universal wheels 11 are installed on the base 1 to facilitate the movement of the simulation device. A channel for vertically installing the drill pipe is left in the center of the support frame 2 and the base 1. Above the support frame 2, a drill pipe guiding device 3 for gripping the drill pipe and performing standpipe operations is installed. A power tong assembly 4 for connecting adjacent parts of two drill pipes is installed between the drill pipe guiding device 3 and the support frame 2. Two sets of casing couplings 5 arranged vertically are installed in the support frame 2 below the power tong assembly 4. The two sets of casing couplings 5 are used to position the drill pipe located below when the power tong assembly 4 connects the drill pipes. A power slip 6 for clamping the lower drill pipe is installed at the bottom of the support frame 2. A plurality of electric push rod assemblies 21 for adjusting the distance from the base 1 are vertically installed on the support frame 2. During use, the power slip 6 first clamps the lower drill pipe, then the casing coupling 5 fixes the upper end of the drill pipe. Subsequently, the drill pipe guiding device 3 erects the remaining drill pipe and inserts it through the channel. During this process, the power tong assembly 4 clamps the inserted drill pipe and drives the drill pipe to rotate and thread-connect with the lower drill pipe.

[0031] For the convenience of drill pipe erection, as Figure 3As shown in the figure, the drill pipe guiding device 3 includes a lifting disc 310, a telescopic support 320, drill pipe clamping jaws 330, a steering servo 340 and an electric push rod 350. A through hole 311 for the drill pipe to pass through is provided in the middle of the lifting disc 310. The telescopic support 320 is in a frame shape, and two telescopic rods 321 with extendable ends are provided on the telescopic support 320. Both of the two telescopic rods 321 are rotatably connected to the surface of the lifting disc 310 on one side of the through hole 311 through bearing seats 322. The top of the telescopic support 320 is connected to the drill pipe clamping jaws 330. A steering servo 340 for adjusting the clamping direction of the drill pipe clamping jaws 330 is installed on the telescopic support 320. There are two electric push rods 350. The two electric push rods 350 are hinged to the surface of the lifting disc 310 on the other side of the through hole 311 through push rod supports, and the extendable ends of the two electric push rods 350 are connected to the telescopic support 320. The telescopic support 320, the electric push rods 350 and the lifting disc 310 are distributed in a triangle. An angle adjustment servo 351 for controlling the working angle of the electric push rod 350 is installed on the lifting disc 310 on one side of the push rod support. Under the control of the electric push rod 350 and the angle adjustment servo 351, the position of the drill pipe clamping jaws 330 on the lifting disc 310 can be easily adjusted, and at the same time, a stable support in the shape of a triangle is formed with the telescopic support 320, so as to ensure the stability of the work of the drill pipe clamping jaws 330 when clamping the drill pipe vertical rod. In addition, when both the electric push rod 350 and the telescopic support 320 extend, the position of the rotating rod clamping jaws 330 can be driven to rise; on the contrary, the position of the rotating rod clamping jaws 330 is driven to drop.

[0032] In order to stably clamp the drill pipe, as Figure 4 shown, the drill pipe clamping jaws 330 include a mechanical jaw bottom plate 331, finger clamping assemblies symmetrically arranged on the bottom plate, and a finger clamping servo 332 for driving the finger clamping assemblies to close or unfold. The finger clamping assemblies include claw force arms 333, clamping plates 334 and claw connecting rods 335. The claw force arms 333 and the clamping plates 334 are sequentially hinged. The claw force arms 333 are rotatably installed on one side of the mechanical jaw bottom plate 331. One end of the claw connecting rod 335 is hinged to the middle of the clamping plate 334, and the other end is connected to the mechanical jaw bottom plate 331. The claw force arms 333, the clamping plates 334, the claw connecting rods 335 and the mechanical jaw bottom plate 331 form a four-claw connecting rod 335 structure. Semi-circular teeth 336 that mesh with each other are processed on the opposite claw force arms 333 of the two finger clamping assemblies. Under the action of the mutually meshing semi-circular teeth 336, the finger clamping servo 332 only needs to drive one of the finger clamping assemblies to realize the clamping operation of the drill pipe clamping jaws 330.

[0033] In order to stably connect the end of the drill pipe, as Figures 5 to 7As shown in the figure, the power tongs assembly 4 includes a power tongs bottom plate 401, a lifting push rod 402, a guide post 403, a chuck support ring 404, a rotating core 407, a power tongs motor 412 and a chuck jaw 414. The power tongs bottom plate 401 is parallel to the lifting plate 310. An lifting push rod 402 for driving the lifting plate 310 to lift and a guide post 403 for keeping parallel to the lifting plate 310 are installed on the power tongs bottom plate 401. A turntable bearing 408 is installed in the middle of the power tongs bottom plate 401. The rotating core 407 is installed on the turntable bearing 408. The rotating core 407 can rotate on the power tongs bottom plate 401 through the turntable bearing 408. An external gear ring 409 is installed at the bottom of the rotating core 407. The power tongs motor 412 is installed on the power tongs bottom plate 401 outside the rotating core 407. The output shaft of the power tongs motor 412 vertically passes through the power tongs bottom plate 401 and then a main gear 413 meshing with the external gear ring 409 is installed. The chuck support ring 404 is slidably sleeved on the outer wall of the rotating core 407. A connecting rod 405 that can move following the lifting plate 310 is installed on the surface of the chuck support ring 404. A limit sliding groove 312 for cooperating with the connecting rod 405 is provided on the through port 311. The connecting rod 405 enables the chuck support ring 404 to only rise and fall following the lifting plate 310. A plurality of chuck jaws 414 distributed radially are installed in the rotating core 407. A slider 415 passing through the rotating core 407 is machined on the outer wall of the chuck jaw 414. A notch 410 for the slider 415 to slide in and out is machined on the rotating core 407. Horizontal strip-shaped grooves 411 are machined on the rotating core 407 on both sides of the notch 410. A limit shaft 416 placed in the strip-shaped groove 411 is installed on the slider 415. A chuck connecting rod 406 hinged with the limit shaft 416 is rotatably installed on the bottom surface of the chuck support ring 404. When the chuck support ring 404 slides up and down along the rotating core 407, it drives a plurality of chuck jaws 414 to close or open simultaneously in the notch 410. The chuck support ring 404, the chuck connecting rod 406, the slider 415, the chuck jaw 414 and the strip-shaped groove 411 constitute a crank-slider mechanism. Under the action of the lifting push rod 402 and the guide post 403, the lifting plate 310 pushes the chuck support ring 404 to slide up and down along the rotating core 407, and during the sliding process, it pushes the crank-slider mechanism to close a plurality of chuck jaws 414 for clamping the drill pipe. At the same time, under the action of the power tongs motor 412, it drives the core shaft to rotate on the turntable bearing 408 to realize the relative rotation of the drill pipe. In order to ensure the stability of the drill pipe connection, a lifting screw module 22 for controlling the lifting of the power tongs bottom plate 401 is further installed on the support frame 2. The lifting screw module 22 can drive the power tongs assembly 4 to move downward when the upper drill pipe rotates to compensate for the distance change caused by the threaded connection.

[0034] In order to ensure the stable connection of the drill pipe, as Figure 8 、 Figure 9As shown, the collar tool 5 includes a cross beam 51, a slide table support 52, a bidirectional lead screw 53, a nut seat 54, a caliper 55 and a polished rod 56. The two cross beams 51 are parallel, and a slide table support 52 is installed on each cross beam 51. The bidirectional lead screw 53 is rotatably installed on one of the slide table supports 52 through a bearing support, and the polished rod 56 is installed on the other slide table support 52. The bidirectional lead screw 53 and the polished rod 56 are parallel. Two nut seats 54 are installed on the bidirectional lead screw 53, and a sliding sleeve 57 opposite to the two nut seats 54 is installed on the polished rod 56. Two calipers 55 are symmetrically installed on the two nut seats 54 and the sliding sleeve 57 along the central axis of the drill pipe. The two sets of collar tools can greatly improve the centering effect of the top of the drill pipe below, improve the connection accuracy, and avoid thread misalignment. To ensure the stability of the drill pipe below, the power slip 6 includes a support seat 61, a drive motor 62, a driving gear 63, a driven gear 64, a double-headed lead screw 65, a guide rod 66 and a slip body 67. The support seat 61 is fixed at the bottom of the support frame 2, and the drive motor 62 is installed on the support seat 61. The driving gear 63 is installed on the output shaft of the drive motor 62. The driven gear 64 is installed on one side of the driving gear 63 and meshes with the driving gear 63. The driven gear 64 is coaxially connected with a double-headed lead screw 65. The two slip bodies 67 are respectively threadedly connected to both ends of the double-headed lead screw 65. The guide rod 66 is parallelly installed on the support seat 61 on one side of the double-headed lead screw 65. Both ends of the guide rod 66 penetrate through the two slip bodies 67 and support the slip bodies 67 to clamp or loosen the drill pipe on the support seat 61.

[0035] The usage method of the present invention is as follows:

[0036] First, the length of the telescopic bracket 320 is controlled by the angle adjustment servo 351 and the electric push rod 350, and then the position of the drill pipe jaw 330 is controlled to make the drill pipe jaw 330 approach the drill pipe. Under the control of the rudder servo 340, the drill pipe is clamped. Subsequently, the drill pipe is made vertical by the angle adjustment servo 351 and the electric push rod 350, and the drill pipe is aligned with the through port 311. Then, the electric push rod 350 shortens, and when shortening, it cooperates with the angle bar adjustment servo to make the drill pipe extend below the through port 311. Until the drill pipe moves down to the mandrel, the lifting push rod 402 on the power tong base plate 401 drives the lifting disc 310 to move down. The downward movement of the lifting disc 310 causes the chuck support ring 404 to be pushed by the connecting rod 405 to move down on the rotating core 407. The downward movement of the chuck support ring 404 causes the chuck link 406 to push the limit shaft 416 on the chuck jaw 414 to slide along the strip groove 411, so that a plurality of chuck jaws 414 are closed and clamp the drill pipe. After the drill pipe is clamped, the drill pipe jaw 330 releases the drill pipe. Subsequently, the power tong motor 412 drives the main gear 413 to mesh with the external gear ring 409 to rotate the drill pipe. At this time, the power slip 6 clamps the lower drill pipe, and the collar connector 5 fixes the end of the drill pipe. At the same time, the lifting screw module 22 drives the entire power tong assembly 4 to move down to compensate for the position difference generated by the threaded rotation connection of adjacent drill pipes, and finally actively completes the connection of the drill pipes.

[0037] After the drill pipes are connected, the drill pipe jaw 330 rises to the top of the drill pipe through the electric push rod 350 and the telescopic bracket 320 and clamps the drill pipe again. The rest of the components release the drill pipe, and the drill pipe guiding device 3 is used to lower the drill pipe. After the drill pipe moves below the drill pipe guiding device 3, the chuck jaws 414 and the power slips 6 on the power tong assembly 4 intermittently clamp the drill pipe, and the lifting screw module 22 is used to continuously lift and lower to drive the drill pipe to move down. After it moves to the designated position, the above steps are repeated to connect the next drill pipe.

[0038] The above are only the preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solutions and inventive concepts provided by the present invention should be covered within the protection scope of the present invention.
