Description

Technical Field

[0001] The invention relates to an ultra-heavy-load oil and gas drilling rig, belonging to the technical field of oil drilling rigs. Background Art

[0002] At present, my country's medium and shallow oil and gas are becoming less and less, and deep and ultra-deep layers are the major strategic replacement areas for my country's oil and gas. As the main battlefield for domestic oil and gas development, the Tarim Basin in Xinjiang currently has newly developed drilling depths of about 9,000 meters, and some blocks have been designed to have a well depth of more than 10,000 meters. Ultra-deep exploration and development technology is extremely difficult and there are many technical problems.

[0003] At present, conventional winches for drilling rigs with a depth of more than 10,000 meters have two reduction gearboxes, four motors, and weigh more than 100 tons. In order to meet the transportation requirements, a split winch is used in the structure. The entire winch is divided into three transportation units: left, middle, and right. The units on the left and right sides are basically the same, that is, the reduction gearbox and two motors. The middle unit consists of a drum shaft assembly, a winch frame, a hydraulic disc brake, etc. When installing, the three parts must be repositioned and installed together.

[0004] The existing oil rig lifting system consists of a crown block, a traveling block, a dead rope holder, a winch, and a wire rope. One end of the wire rope is fixed to the dead rope holder, the middle part of the wire rope is supported by the crown block pulley and the traveling block and the big hook are suspended, and the other end of the wire rope is fixed to the drum of the winch. Only one set of wire ropes is used for lifting in the lifting system.

[0005] For ultra-deep well drilling rigs over 10,000 meters, due to the gravity of the traveling block, the hoisting rope and the drilling wire rope form a certain angle α during lifting, causing interference and wear between the drilling wire rope and the shield of the traveling block. For ultra-deep well drilling rigs over 10,000 meters, the traveling block is very heavy, reaching 19 tons. The heavier the traveling block, the more serious the interference and wear.

[0006] During drilling conditions, the speed of the internal pulley block is different when the traveling block moves up and down, resulting in unbalanced forces, which will cause a certain swing angle and lead to interference and wear between the drilling wire rope and the protective cover.

[0007] The interference and wear between the wire rope and the shield mentioned above will result in shortened service life of the drilling wire rope, shortened rope cutting cycle of the drilling wire rope, and increased drilling time. In severe cases, drilling accidents may occur if the rope is not cut in time. What is more serious is that during drilling conditions, sparks are generated due to friction between the wire rope and the shield. If combustible gas overflows from the wellhead and ignites, it will cause a major explosion and combustion accident. Summary of the invention

[0058] In this embodiment, the design of the winch 3 and the brake device can effectively control the entire movement process of the winch 3, which can further solve the working conditions of the entire lifting operation and drilling operation, thereby effectively improving the lifting efficiency of the derrick 2 and the working efficiency of the drilling rig.

[0059] In this embodiment, the winch 3 is provided with a drum 31. As one specific implementation method, the winch 3 also includes a box structure matched with the drum 31.

The drum 31 is rotatably arranged between the two wall plates 32. An installation gap for installing a disc brake device 35 is formed between the back plate 38 and the two wall plates 32 respectively.

[0060] The wall panel 32 further includes a cross beam 37 , which is arranged across the wall panel 32 .

[0061] The installation gap between the back plate 38 and the wall plate 32 is reasonably designed, which not only ensures the effective clamping of the disc brake device 35, but also avoids the contamination of the brake system by the wire rope lubricating oil, ensuring the stability and reliability of the braking performance. In addition, the disc brake device 35 is installed on the back of the back plate 38, and there is no need to increase the distance between the two wall plates 32, thereby ensuring the strength of the winch 3 box.

[0062] In order to better achieve the braking effect of the winch 3, in the specific structural design, the brake device includes a brake disc 34 arranged at one end or both ends of the drum 31, the brake disc 34 is arranged on the inner side or outer side of the wallboard 32, and the brake device also includes a disc brake device 35 arranged on the base 1, the brake disc 34 matches the disc brake device 35, and the disc brake device 35 is driven to open / close by a disc brake driving device 3636.

In this structure, the structural design of the brake disc 34 and the disc brake device 35 can effectively provide a braking effect for the winch 3, and the automatic effect of the winch 3 working and braking at any time is effectively achieved through the design of this method. In the design of this embodiment, the disc brake device 35 is mainly driven by a hydraulic drive method and connected to a hydraulic station, so as to be integrated with the entire drilling rig system.

[0063] As a more specific design, an opening is formed on the wall panel 32, and the wall panel 32 is provided with an inserting plate 315 and at least two connecting plates 313, the inserting plate 315 can be inserted into the opening, the inserting plate 315 is arranged between the two connecting plates 313 and connected to the two connecting plates 313, the inserting plate 315 is detachably connected to the wall panel 32 through the connecting plates 313, and after the inserting plate 315 is installed, it forms a mounting hole 39 matching the drum 31 with the wall panel 32;

[0064] Both ends of the plug plate 315 abutting against the wall panel 32 are formed with a first snap-fitting portion 310 along the insertion direction of the plug plate 315, and one end of the connecting plate 313 is formed with a second snap-fitting portion 311, and the first snap-fitting portion 310 can be snapped with the second snap-fitting portion 311 to connect the plug plate 315 to the connecting plate 313.

[0065] In the design of the above-mentioned specific structure, the design of the structure can facilitate the assembly of the drum 31 structure, further improving the assembly efficiency of the winch 3. The structure is simple and easy to maintain and operate.

[0067] In the design of this structure, as a usage instruction, the brake disc 34 protrudes partly along the wall panel 32 after the drum 31 is assembled, so as to facilitate the cooperation and braking of the disc brake device 35. This is mainly due to the protection and setting of the entire shell structure. Therefore, there is a gap between the back panel 38 and the wall panel 32 for the extension of the brake disc 34, thereby ensuring the operation and braking of the winch 3 and further optimizing the component position layout on the entire base 1.

[0070] Each group of the drilling rig wire rope hoisting systems can operate independently, or each group of the wire rope hoisting systems can be interconnected to operate together.

[0071] The swimming system further comprises a suspension member 12 and a first load-bearing connecting member 13;

[0072] The suspension member 12 is arranged just above the wellhead and mounted on the derrick 2. Each set of the crown block 4 includes at least one fixed pulley, which is detachably connected to the suspension member 12. The fixed pulleys of the two sets of crown blocks 4 are symmetrical about the center line of the wellhead.

[0073] The traveling block 5 includes at least one movable pulley, the lower end of which is detachably connected to the first load-bearing connector 13, and the two sets of movable pulleys of the traveling block 5 are symmetrical about the center line of the wellhead.

[0074] Alternatively or alternatively, the travel system further comprises a translation device 14, a crown block coupling 15 and a second load-bearing connection member 16;

[0075] The crane 4 is slidably connected to the derrick 2 in the horizontal direction, and two groups of the cranes 4 are detachably connected through the crane coupling 15. The translation device 14 is installed on the derrick 2 and connected to each group of the cranes 4, and can push the cranes 4 to reciprocate in the horizontal direction, so that the center line of each group of the cranes 4 or the center lines of the two groups of the cranes 4 are aligned with the center line of the wellhead;

[0076] The second load-bearing connecting member 16 is disposed below the traveling block 5 , and two groups of the traveling blocks 5 are detachably connected via the load-bearing connecting member.

[0080] Based on the design of the above-mentioned specific structure, as a more specific design, the traveling system also includes fixed pulleys arranged on both sides of the base section of the derrick 2, and a lifting rope 7 for lifting the derrick 2. One end of the lifting rope 7 is fixedly connected to the traveling block 5, and is fixed to the middle part of the derrick 2 after passing through the fixed pulley.

[0081] As a usage illustration, in a specific operation, when the derrick 2 is lifted, the two rollers 31 work synchronously to lift the derrick 2 through the traveling block 5. After the lifting is completed, the connection between the lifting rope 7 and the traveling block 5 is removed and fixed.
