Description

Technical Field

[0001] The invention relates to an oil well drilling and workover rig in an oil and gas field, in particular to a rope guiding device for a rope rewinding machine on a drilling table of a fast-moving drilling rig and a use method thereof. Background Art

[0002] With the development of rapid transportation technology for land drilling rigs, drilling rigs with fewer transport modules, low manufacturing and use costs, good passability, fast moving speed, high level of automation, efficient operation and easy maintenance are becoming more and more popular among users.

[0003] At present, the drilling wire rope of the traveling and hoisting system of land drilling rigs is basically threaded in a straight line. That is, the drilling rope from the rope rewinding machine passes through the dead rope fixer, the main pulley block of the crown block, the traveling block, the fast rope pulley block of the crown block, and then to the main winch to form the entire traveling and hoisting system. In the traveling and hoisting system, the dead rope fixer is often arranged on the first main body on the right side of the derrick. In order to facilitate the threading and replacement of the drilling rope, the corresponding rope rewinding machine is also arranged on the same side as the dead rope fixer. As the supply end of the drilling rope, the rope rewinding machine can be placed on the ground, on the side of the base, on the side of the table, and in front of the table in the layout of the drilling rig. Different placement positions will directly affect the operating efficiency, use and maintenance costs, and transportation and moving time of the drilling rig.

[0004] In the case where the rope rewinder is arranged on the ground, in addition to occupying the well site area, the rope of the rope rewinder passes through the entire base in the height direction and then to the dead rope holder. On its path, the wire rope must avoid interference with the base structure and various equipment. The base must also reserve an installation channel for the wire rope to enter the base from the outside of the base. There are installation sequence requirements when installing the drilling rig. The base structure design is complex, the on-site operation is inconvenient, and there are many transportation modules when the drilling rig is moved, and the operation efficiency is not high. In the case where the rope rewinder is arranged on the side of the base, in addition to the above problems, the additional bracket for placing the rope rewinder can be transported with the base, but it greatly increases the transportation width of the bottom of the main machine. In specific use areas, such as: Oman, the transportation requirements for fast-moving drilling rigs are below 4m and the transportation width does not exceed 11m, and its passability is poor. During transportation, if there is a width limit requirement, the rope rewinder needs to be disassembled or the rope rewinder needs to be relocated and transported separately, which is inefficient for moving. In the case where the rope rewinding machine is installed on the side of the table, the drilling wire rope is often used to be pulled out from the bottom of the rope rewinding machine. Although the rope rewinding machine can be transported as a whole with the base, it has good passability. However, the table is designed with a sunken groove for storing the drilling rope between the rope rewinding machine and the dead rope holder. When the drilling rope is taken out or stored in the groove, it is difficult and troublesome for on-site personnel to operate due to the large diameter of the wire rope and its difficulty in bending. At the same time, the wire rope placed in the groove has the risk of surface wear and rust caused by soaking in mud. There is a safety hazard of tripping when the rope is pulled out from the rope rewinding machine, and the table deck structure design is complicated. In the case where the rope rewinding machine is placed in front of the base table, the drilling wire rope is used to pull out from the bottom of the rope rewinding machine, which can be transported as a whole with the base, and has good passability. However, for the slingshot base, the rope rewinding machine needs to be removed for the lifting and lowering of the base and low-level transportation conditions, which is inconvenient to operate and the moving efficiency is not high.

DETAILED DESCRIPTION

[0049] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0051] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0052] Embodiment 1

[0053] A rope guide device for a fast-moving drilling rig drilling table rope rewinder, such as Figure 1-Figure 4 and Fig.10 As shown, it includes a rope rewinding machine 1 and a dead rope fixer 2 arranged on a base, and a guide bracket 3 is provided between the rope rewinding machine 1 and the dead rope fixer 2; the wire rope comes out from the top of the rope rewinding machine 1, passes through the guide bracket 3, and then enters the bottom rope inlet of the dead rope fixer 2.

[0054] Specifically, in this solution, the rope reel 1 discharges the rope from the top, which can reduce the contact between the wire rope and the ground or other objects, thereby reducing wear and tear, and reducing the risk of operators being tripped by tangled or loose wire ropes during operation. In addition, since the wire rope is heavy and has a tendency to sag, when it is directly connected between the rope reel 1 and the dead rope holder 2, the middle part of the wire rope bends downward, blocking the passage, and the guide bracket 3 can guide the wire rope to move along a predetermined path, preventing the wire rope from deflecting or jumping during operation, and will not interfere with other parts of the drilling rig, thereby avoiding potential failures and safety risks. Among them, the guide bracket 3 is not lower than the rope outlet of the rope reel 1, and the wire rope is discharged from the top of the rope reel 1, and passes through the guide bracket 3 upward or parallel to ensure that the tension of the wire rope from the rope outlet of the rope reel 1 to the dead rope holder 2 remains constant, and ensure that the passage is not blocked. Therefore, by using the rope guide device, the rope rewinding machine can be conveniently arranged on the base table, the wire rope will not interfere with the table equipment, will not block the operator's passage, will not damage the drilling wire rope, and there is no safety hazard. When replacing the drilling rope, no crane is required, and the operator only needs to perform the rope feeding operation on the table. The rope rewinding machine is arranged on the base and can be transported as a whole with the base. The transportation width is not limited and the passability is better. Furthermore, the guide bracket 3 is arranged within the axial range of the roller of the rope rewinding machine 1 to prevent the wire rope from tilting out of the rope and causing friction with the edge of the roller or other structures, or axial sliding of the wire rope. The drilling rope coming out of the rope rewinding machine first passes through the guide bracket 3 installed on the derrick, and finally enters the dead rope holder 2. The drilling wire rope will be supported on the guide bracket 3 and correctly guided to the dead rope holder 2 to meet the requirements of drilling and fast movement.

[0055] As another specific implementation, Figure 5 As shown, the guide bracket 3 includes a bracket body 31, and the bracket body 31 is arranged on the derrick, and the bracket body 31 is connected to a guide roller assembly 32. The bracket body 31 is arranged on the derrick, and there is no need to re-erect the supporting elements, which helps to concentrate the wellhead operation area and reduce the floor space. The guide roller assembly 32 can reduce the direct contact between the wire rope and the bracket, thereby reducing wear and extending the service life of the wire rope. When the wire rope is replaced, rolling friction is used instead of sliding friction, which significantly reduces the friction of the wire rope during movement, making the movement of the wire rope smoother. Furthermore, the bracket body 31 and the guide roller assembly 32 can be fixedly connected by welding, or can be connected in a detachable manner such as bolts. The guide roller assembly 32 is connected to the bottom of the bracket body 31.

[0056] As another specific implementation, Figure 5As shown, a first ear seat 311 is provided on the side of the bracket body 31, and the first ear seat 311 is rotatably connected to the derrick. The hinged structure allows the wire rope guide bracket 3 to swing at a certain angle when the derrick moves or is acted upon by an external force, so as to better adapt to the actual position change of the wire rope and maintain the stable guidance of the wire rope.

[0057] As another specific implementation, Figure 6 As shown, the guide roller assembly 32 includes a support 321, in which a pair of horizontal rollers 322 and a pair of vertical rollers 323 arranged in a "well" shape are arranged. The bottom of the support 321 is provided with a first notch that runs through the front and back, and the side of the support 321 is provided with a second notch that runs through the front. Due to the "well"-shaped layout, the wire rope can move in multiple directions, not just a single horizontal or vertical direction, providing a more flexible guiding path for the wire rope. And reduce the direct contact between the wire rope and the support 321, thereby reducing friction and wear, and extending the service life of the wire rope.

[0058] As another specific implementation, the horizontal rolling bar 322 and the vertical rolling bar 323 are respectively connected to the support 321 through a pin shaft 324; a copper sleeve 325 is provided between the horizontal rolling bar 322 and / or the vertical rolling bar 323 and the pin shaft 324 therein. The copper sleeve 325, as a friction-reducing material, can reduce direct metal contact between the rolling bar and the pin shaft 324, thereby reducing the wear rate and extending the service life of the rolling bar and the pin shaft 324.

[0059] As another specific embodiment, the bottom of the support 321 has a strip opening, and the strip opening is covered with a detachable bottom plate 326. The bottom plate 326 is removed from the support 321 when the rope is installed. The strip opening can facilitate the installation of the wire rope. After the wire rope is installed, the bottom plate 326 is reinstalled to maintain the strength of the support 321. The support 321 is a steel plate welded structure. At the open position at the bottom of the support 321, after the drilling wire rope is threaded, a connecting plate, steel wire, bolts, and flat washers are installed to increase the overall strength and rigidity of the entire support 321.

[0060] As another specific embodiment, the bottom of the support 321 is provided with a first notch 327 facing the rope rewinding machine 1. The first notch 327 allows the steel wire rope to pass through when it comes out of the rope rewinding machine 1 and moves upward, thereby preventing the interference between the bottom plate 326 and the steel wire rope and thus causing wear of the steel wire rope. Specifically, the bottom plate 326 covers a part of the strip opening, and the other part of the strip opening forms the first notch 327.

[0061] As another specific embodiment, the side of the support 321 is provided with a second notch 328 facing the dead rope fixer 2 and / or a third notch 329 facing the rope rewinding machine 1. Similarly, the second notch 328 and the third notch 329 can also prevent the wire rope from interfering with the support 321 when connected to the dead rope fixer 2 and the rope rewinding machine 1. Specifically, the second notch 328 is located between the two rolling bars 322.

[0062] As another specific implementation, Figure 8 As shown, the guide bracket 3 is arranged on the derrick through the derrick embedded part 4, and the derrick embedded part 4 includes a box beam 41 fixedly connected to the derrick, and a second ear seat 42 is provided on the side of the box beam 41. Specifically, the box beam 41 provides an installation position, and the second ear seat 42 cooperates with the first ear seat 311 to realize the rotatable installation of the guide bracket 3. After being welded together, the whole is welded with the right section of the derrick for installing the guide bracket 3.

[0063] As another specific implementation, Figure 7 As shown, it also includes a guide pulley assembly 5 arranged below the dead rope fixer 2. Since the dead rope fixer 2 needs to meet the rope feeding from below, and the approach point provided by the guide bracket 3 is not lower than the rope rewinding machine 1, when the dead rope fixer 2 is shorter, the wire rope will move downward through the guide bracket 3 and then enter the dead rope fixer 2 upward. At this time, the bending radius of the wire rope can be controlled by the guide pulley assembly 5 to prevent the wear of the wire rope and interference with other drilling rig components. At the same time, the guide pulley assembly 5 can limit the wire rope to pass through the bottom of the dead rope fixer 2 first, and then enter the rope from the bottom rope inlet of the dead rope fixer 2, providing more precise position control, avoiding interference with the structure of the dead rope fixer 2, and reducing wear. Preferably, the left and right positions of the guide pulley assembly 5 meet the rope outlet position and the rope feeding position of the dead rope fixer 2 on the same line, and the height position is convenient for the operator to operate the pulley 53. The twisting and lateral force of the rope at the fixed point are reduced, the risk of accidental loosening of the rope is reduced, and the safety of operation is improved.

[0064] As another specific embodiment, the guide pulley assembly 5 includes a support member 51, a third ear seat 52 is provided on the support member 51, a pulley 53 is provided on the front side of the support member 51, a pulley seat 54 is provided on the rear side of the pulley 53, a pressure plate 55 is provided on the front side of the pulley 53, and a limiter 56 is provided between the pulley seat 54 and the pressure plate 55, and the limiter 56 is located at the periphery of the pulley 53. The support member 51 is used to fix and support the pulley 53; the third ear seat 52 is used to install the guide pulley assembly 5 to a specified position; the pulley 53 is used to guide the wire rope and reduce friction. The limiter 56 provided on the periphery of the pulley 53 can limit the periphery of the wire rope to prevent the drilling wire rope from escaping from the rope groove of the pulley 53 after installation, and the limiter 56 can be fixed by the pressure plate 55 and the pulley seat 54. The pulley 53 is reliably fixed on the welded structure composed of the support 51 and the third ear seat 52 through a pressure plate, round nuts, bolts, flat washers, steel wires, and stoppers. The stopper 56 is a seamless steel pipe, which is installed around the pulley through bolts, flat washers, split pins, and slotted nuts.

[0065] As another specific embodiment, the radial direction of the pulley 53 is inclined toward the rope outlet of the guide roller assembly 32. Since the wire rope directly passes from the rope outlet of the guide roller assembly 32 to the pulley 53, the present configuration is that the axis of the pulley 53 is perpendicular to the rope feed angle of the wire rope, and the inclined pulley 53 can reduce the concentrated wear of the wire rope and the rim of the pulley 53, and the wire rope is more easily kept in the rope groove of the pulley 53, reducing the risk of slot jumping.

[0066] As another specific implementation, Fig. 9 As shown, the guide pulley assembly 5 is arranged on the base through the base embedded part 6, and the base embedded part 6 includes a fourth ear seat fixedly connected to the base. The fourth ear seat is welded to the base at the front support leg of the derrick under the dead rope fixer 2, and is used to install the guide pulley assembly 5. No additional support structure is required, which ensures a compact structure and enables the guide pulley assembly 5 to move with the base. The fourth ear seat is connected to the third ear seat 52 to realize the installation of the guide pulley assembly 5.

[0067] Optionally, the ends of the horizontal roller bar 322, the vertical roller bar 323 and the pulley 53 are all equipped with straight-through oil cups for filling grease and lubricating the rotating shafts of the roller bar and the pulley 53 to enable them to rotate flexibly.

[0068] Embodiment 2

[0069] The method for using the rope guide device for the rope rewinding machine on the drilling table of a fast-moving drilling rig comprises the following steps:

[0070] S1. Pre-installation:

[0071] S1.1. Install the derrick embedded parts on the right section of the derrick according to the placement of the rope rewinder on the table and the direction of the rope output;

[0074] S2.1. Thread the drilling wire rope through the traveling system in a straight-through manner;

[0075] S2.2, lifting the derrick;

[0076] S2.3. Remove the bottom plate and a transverse roller of the guide roller assembly, lift the wire rope through the guide roller assembly to a height that is convenient for installing the removed transverse roller. After the transverse roller and bottom plate are installed, the wire rope is supported on the guide bracket.

[0077] At this point, the wire rope guide device of the rope reversing machine has been installed, and the remaining ropes are threaded according to the rope threading diagram of the traveling hoist system.

[0078] As another specific implementation, in step S2, the wire rope comes out from the top of the rope rewinding machine, passes through the guide bracket upward or parallel, and then enters the bottom rope inlet of the dead rope fixer.

[0079] This method can ensure that the tension of the wire rope from the outlet of the wire rope rewinding machine 1 to the dead rope holder 2 remains constant, and ensure that the passage is not blocked. Therefore, by using the rope guide device, the wire rope rewinding machine can be conveniently arranged on the base table, the wire rope will not interfere with the table equipment, will not block the operator's passage, will not damage the drilling wire rope, and there is no safety hazard. When replacing the drilling rope, no crane is required, and the operator only needs to feed the rope on the table.

[0080] Embodiment 3

[0081] Based on the previous embodiment, in this embodiment, S1 further includes the following steps:

[0082] S1.3. Weld the embedded base parts for installing the guide pulley assembly at the bottom of the dead rope fixer and the base at the right front leg of the derrick;

[0083] S1.4. Install the guide pulley assembly;

[0084] The S2 also includes the steps of:

[0085] S2.4. Pass the steel wire rope through the rope groove of the guide pulley assembly installed on the base. After the steel wire rope is wound, install the limiter to prevent the steel wire rope from coming off.

[0086] In the step S2, after the wire rope comes out from the guide bracket, it passes through the guide pulley assembly below the dead rope fixer and then enters the rope from the bottom rope inlet of the dead rope fixer.

[0087] When the dead rope holder 2 is shorter, the wire rope will move downward through the guide bracket 3 and then upward into the dead rope holder 2. At this time, the guide pulley assembly 5 can control the bending radius of the wire rope to prevent the wear of the wire rope and interference with other drilling rig components. At the same time, the guide pulley assembly 5 can limit the wire rope to pass under the dead rope holder 2 first, and then enter the rope from the bottom rope inlet of the dead rope holder 2, providing more precise position control, avoiding interference with the structure of the dead rope holder 2, and reducing wear.

[0088] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
