Description

Technical Field

[0001] This invention belongs to the field of petroleum machinery and equipment technology, specifically relating to a drilling device with offline root establishment function. Background Technology

[0002] Currently, with the development of automated drilling technology and equipment, the intensity of manual labor in the drilling process has been effectively reduced. However, due to the reliability of the equipment and the proficiency of human-machine cooperation, the efficiency of drilling operations has not been greatly improved. The best way to further improve the efficiency of drilling operations, especially the efficiency of ultra-deep well drilling operations with high height and heavy load, is to adopt offline root establishment technology. However, conventional jacking derrick bases not only cannot meet the offline root establishment function, but also the derrick bases are all lifted by steel wire ropes, which requires changing the lifting rope, posing a risk of high-altitude operations. The installation and dismantling efficiency is relatively low, and it cannot meet the future development requirements of drilling rigs towards large hook loads and ultra-deep well operations. Summary of the Invention

[0039] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0040] A drilling rig with offline root establishment function includes a base 8, a derrick 2 hinged on the base 8, a crane 1 installed on the upper end of the derrick 2, and a composite lifting device jointly provided on the derrick 2 and the base 8. The derrick 2 completes lifting through the composite lifting system.

[0041] Furthermore, the composite hoisting system includes a first winch 10, which is mounted on the base 8. A second guide pulley is provided on the crane 1. A drilling rope is wound around the first winch 10, and the free end of the drilling rope passes through the second guide pulley and connects to the traveling block 24. Additionally, an A-frame 23 is mounted on the base 8. The derrick 2 is detachably connected to the A-frame 23 via a pin. The A-frame 23 specifically includes a connecting beam 29. One end of the connecting beam 29 is connected to a front leg 30 of the A-frame, and the other end is connected to a rear leg 31 of the A-frame. A-frame pulleys 27 are located on the connecting beam 29. Both the front leg 30 and the rear leg 31 of the A-frame are specially designed double-column truss load-bearing structures. A-frame pulley 27 is installed on the upper end of the crossbeam 29. The derrick 2 is equipped with an inner lifting pulley, an outer lifting pulley, and an upper lifting pulley 25. The traveling carriage 24 is connected to a lifting rope 26. There are two lifting ropes 26, which are symmetrically distributed on both sides of the derrick 2. One end of the rope is connected to the traveling carriage 24 through a lifting tripod. The other end passes through the inner lifting pulley, outer lifting pulley, upper lifting pulley 25, and A-frame pulley 27 on the derrick 2 and is connected to the ear plate of the A-frame rear leg 31. The ropes are fixed by the pin. During the lifting of the derrick 2, the two lifting ropes 26 work together to make the derrick 2 lift smoothly. The composite lifting system also includes a hydraulic cylinder 9, which is installed in the base 8.

[0042] The base 8 is equipped with a hydraulic cylinder 9. Specifically, the base 8 includes an upper seat 35, with several columns 34 hinged to the lower end of the upper seat 35. A middle base 22 is hinged to the free end of each column 34. The columns 34 are arranged in parallel to ensure the upper seat 35 can move up and down. Several parallel inclined columns are also provided between the upper seat 35 and the middle base 22 to ensure its stability. The upper end of the hydraulic cylinder 9 is connected to the bottom end of the upper seat 35, and the lower end of the hydraulic cylinder 9 is connected to the middle base 22. Under the action of the hydraulic cylinder 9, the upper seat 35 can be raised from a low position to a high position. The hoisting system and hydraulic cylinder 9 together form a composite hoisting system, which together lifts the derrick 2 and base 8 from a flat position to an upright position. One end of the middle base 22 is connected to the front base 21, and the other end of the middle base 22 is connected to the rear base 36. The first winch 10 is installed on the rear base 36. The lower support legs of the derrick 2 are connected to the middle base 22 of the base 8 by pins. The front leg 30 and the rear leg 31 of the A-frame are symmetrically installed on the middle base 22 of the base 8 and connected to the middle base 22 by pins.

[0043] In use, both the derrick 2 and the base 8 are in a low-positioned front position before lifting. When the base 8 is installed horizontally in a low position, the upper seat 35 is tilted forward and placed on the front base 21. The lower support 18 of the traveling block is placed in front of the base 8 and in the center. It is connected to the base 8 as a whole by the tie rod 19. A low support 17 is provided near the overhead crane 1 to support the weight of the entire derrick 1 and the equipment on it, ensuring that the derrick 1 is in a horizontal state. Before lifting, with the support of the low support 17, each piece of the derrick 2 is assembled in sequence, and then the overhead crane 1 is installed. After all the accessories are assembled, the derrick 2 is lifted from the low support 17 in the low position to the high support 28 by a crane. Then the third-level platform 4 and the second-level platform 15 are installed. The drilling rope on the first winch 10 is passed around the second guide pulley of the overhead crane 1 and connected to the traveling block 24. The first winch 10 is started, and the traveling block 24 is moved towards the overhead crane by the drilling rope. At the same time, the hoisting rope 26 is pulled, and the derrick 2 is gradually lifted from a horizontal state to an upright state.

[0044] Once the derrick 2 is raised to a vertical working position, connect and securely fix the derrick 2 to the A-frame 23 using U-bolts or ear plate pins. Then, disconnect the hoisting rope 26 from the hoisting triangle on the traveling block 24, fix the end of the hoisting rope 26 in the derrick rope hanger, and lower the traveling block to a low position. The hoisting of the derrick 2 is now complete. Next, operate the hydraulic cylinder 9 to slowly extend, pushing the upper seat of the base 7 to slowly rise until the hydraulic cylinder 9 is in an upright position. Then, connect and fix the base 8 to the derrick 2 using pins, and fix the column 34 to the middle base 22 using pins, thus completing the hoisting of the base 8.

[0045] The derrick 2 is equipped with an offline root-establishing device, which includes a crane 1 located at the upper end of the derrick 2. The crane 1 is fitted with two first guide pulleys 13. A pipe-lifting manipulator rail 16 is longitudinally mounted on the front column of the derrick 2, with a matching pipe-lifting manipulator 3 sliding within the rail 16 to ensure its vertical movement. A second winch is mounted on the base 8, specifically on the rear base 36. A steel wire rope is wound around the second winch, with its free end passing through the first guide pulleys 13 and connecting to the pipe-lifting manipulator 3. The first guide pulleys 13 are used to provide positional guidance for the drilling... The hoisting manipulator 3 on the right side of the platform is guided by the winch wire rope and supports the operation of the hoisting manipulator 3. After the derrick base is lifted, the top drive and buffer manipulator can be installed, the second winch can be started, and the hoisting manipulator 3 can be driven to slide up and down along the hoisting manipulator guide rail 16 via the wire rope to connect the erector 6. The front side of the derrick 2 is equipped with a second-level platform 15 and a third-level platform 4 from bottom to top. They are connected to the front column of the derrick 2 and fixed as one unit by the pin. The third-level platform 4 is equipped with a pipe laying manipulator 5, which can be used to lay the erector 6. The upper end of the upper seat 35 is connected to the erector platform 7 by the pin. The erector platform 7 includes a front erector platform 32 and a rear erector platform 33.

[0046] Among them, the back crossbeam of derrick 2 has an arched structure, which meets the requirements for the installation and working space of the buffer manipulator and realizes the offline root establishment function requirements of the drilling rig. The top drive guide rail 14 is installed on the back crossbeam of derrick 2. The top drive guide rail 14 is connected to the back crossbeam of derrick 2 and is fixed into one piece by bolts, nuts and washers.

[0047] Both the lifting guide rail 16 and the top drive guide rail 14 are segmented truss structures. Their connection method is as follows: the segments of the lifting guide rail 16 are positioned by male and female cones. Each segment of the lifting guide rail 16 is fixedly connected with a connecting lug. The connecting lug is connected to a first lug 37 by a pin. The first lug 37 is connected to a second lug 39. The second lug 39 is connected to the derrick 2. A shim 38 is provided between the first lug 37 and the second lug 39 to adjust the straightness of the lifting guide rail 16.

[0048] The front water tank 11 and the rear water tank 12 are respectively installed on the rear base 36 via pins to meet the counterweight requirements for the hoisting of the derrick. The first winch 10 and the second winch are both installed above the front water tank 11. The rear base 36 is equipped with an integral towing bar 20. The integral towing bar 20 adopts a double-layer through-type structure. After passing through the web plates of the two base beams of the rear base 36, the integral towing bar 20 is welded to the rear base 36 to form an integral whole, which can meet the requirement of towing the entire derrick base in an emergency.

[0049] Example 1

[0050] When the derrick 2 is being lifted, both the derrick 2 and the base 8 are in a low-positioned forward position before lifting. When the base 8 is installed horizontally in its low position, the upper seat 35 is tilted forward and placed on the front base 21. The lower traveling block support 18 is placed in front of the base 8 and centered, and connected to the base 8 as a whole by the tie rod 19. A low support 17 is provided near the overhead crane 1 to support the weight of the entire derrick 1 and the equipment on it, ensuring that the derrick 1 is in a horizontal state. Before lifting, with the support of the low support 17, each piece of the derrick 2 is assembled in sequence, and then the overhead crane 1 is installed. After all the accessories are assembled, the derrick 2 is lifted from the low position of the low support 17 to the high position using a crane. On the derrick 28, install the third-level platform 4 and the second-level platform 15; connect the drilling rope on the first winch 10 to the traveling block 24 by passing it around the second guide pulley of the overhead crane 1; start the first winch 10, and drive the traveling block 24 towards the overhead crane via the drilling rope, while simultaneously pulling the hoisting rope 26, together gradually lifting the derrick 2 from a horizontal state to an upright state. When the derrick 2 is lifted to a vertical working state, connect and fix the derrick 2 to the A-frame 23 securely using U-bolts or ear plate pins; then disassemble the hoisting rope 26 from the hoisting triangle on the traveling block 24, fix the end of the hoisting rope 26 in the derrick rope hanger, and lower the traveling block to a low position, thus completing the lifting of the derrick 2. Next, the hydraulic cylinder 9 is slowly extended, pushing the upper seat of the base 7 to rise slowly until the hydraulic cylinder 9 is in an upright position. Then, the base 8 is connected and fixed to the derrick 2 with a pin, and the column is fixed to the middle base 22 with a pin, thus completing the lifting of the base 8.

[0051] Example 2

[0052] After the derrick base is lifted, the top drive and buffer manipulator can be installed, the second winch can be started, and the pipe lifting manipulator 3 can be driven up and down along the pipe lifting manipulator guide rail 16 via the wire rope to connect the upright root 6. The pipe laying manipulator 5 installed on the three-layer platform 4 can perform the laying operation of the upright root 6 on the three-layer platform 4.
