Description

Technical Field

[0001] This invention belongs to the technical field of petroleum drilling equipment, and relates to a long-span longitudinal and transverse bidirectional cluster well drilling rig cable transportation system. This invention also relates to a long-span longitudinal and transverse bidirectional cluster well drilling rig cable transportation method. Background Technology

[0002] With the continuous advancement of oil drilling rig application technology, large-span cluster drilling rigs with both longitudinal and transverse spans are becoming increasingly common, significantly improving equipment utilization and maximizing oil and gas resources. Moving this type of rig requires supporting cables and pipelines hundreds of meters long, and the cable transport system must adopt a modular design to effectively meet the requirements of rapid longitudinal and transverse movement and overall transportation. The existing technical solution to this problem is to deploy a surface cable transport system during longitudinal rig movement. After drilling one row of wells, a crane is used to move the cable transport system to the next row of wells for continued operation. The disadvantages of this method are: it requires crane and personnel to be involved in the entire cable transport process; the cable needs to be repeatedly disassembled and reassembled; the labor intensity for workers is high; the transport efficiency is low; and the cables are easily damaged or broken. Summary of the Invention

[0003] The purpose of this invention is to provide a long-span, longitudinal and transverse bidirectional cluster drilling rig cable transfer system, which solves the problems of existing technologies that require cranes and personnel to participate in the entire cable transfer process, require repeated disassembly and assembly of the cable, result in high labor intensity for workers, low transfer efficiency, and easy damage and breakage of the cable.

[0004] Another objective of this invention is to provide a method for moving the cable of a long-span, longitudinal and transverse bidirectional cluster drilling rig.

[0005] The technical solution adopted in this invention is a long-span, longitudinal and transverse bidirectional cluster drilling rig cable transfer system, including a cable storage rack, a short extension rack, a long extension rack, and an elevated folding arm transfer bridge. The cable storage rack is a frame structure, with a guide rail 1 set along the center line at the top of the cable storage rack. In the initial state, a cable transfer box I is set on the front section of the guide rail 1, and a saddle is set on the middle section of the guide rail 1. An electric winch is installed at the tail end of the cable storage rack. A guide rail 2 is set along the center line at the top of the short extension rack, and a guide rail 3 is set along the center line at the top of the long extension rack. Before the transfer operation, the two ends of the guide rail 2 are connected to the guide rail 1 and the guide rail 3 respectively, forming the main guide rail. The saddle moves forward along the main guide rail, suspending the cables and unfolding them in sequence.

[0006] Another technical solution adopted in this invention is a method for moving cables of a large-span longitudinal and transverse cluster drilling rig. This method utilizes the aforementioned large-span longitudinal and transverse cluster drilling rig cable moving system, including a longitudinal moving method and a transverse moving method. The working process of the longitudinal moving method is as follows:

[0007] Step 1: According to the layout of the wellhead at the drilling site, arrange the cable storage rack and short extension rack in sequence at the front end of the VFD room, and connect the guide rail 1 and guide rail 2 at the top of the cable storage rack and the short extension rack; the high-pressure manifold connecting the mud pump group passes through the bottom of the short extension rack and reaches the drilling rig host; connect the base connecting bracket with the fixed sleeve support frame to the drilling rig host with a pin shaft, and connect the elevated folding arm transfer bridge to the sleeve support frame and the support frame with flanges respectively; the cable led out from the electrical control room is transferred through the cable transfer box I at the front end of the short extension rack and enters the elevated folding arm transfer bridge, and then through the cable transfer box II on the drilling rig host and enters the interior of the drilling rig host;

[0008] Step 2: Before the drilling rig is prepared for longitudinal movement, firstly, install a long extension frame at the front end of the short extension frame, which is the same length as the longitudinal well spacing, and connect the guide rails 2 and 3 at the top of the two along the center line; disconnect the longitudinal joint of the high-pressure manifold; secondly, use external force to pull the cable transfer box 1 at the front end of the short extension frame and the saddle for suspending the cable forward along the guide rail 3 of the long extension frame.

[0009] When the drilling rig is moved longitudinally to the new wellhead, a high-pressure manifold short section of the same length as the longitudinal well spacing is installed at the longitudinal joint of the high-pressure manifold to connect the pipelines and cables between the various components of the drilling rig, thus completing the movement of one longitudinal well spacing.

[0010] Step 3: Before each relocation, install a new long extension frame at the front end of the long extension frame of the suspended cable junction box I, with the same length as the longitudinal well spacing. Repeat the above steps to complete the continuous longitudinal relocation of the drilling rig well location.

[0011] The beneficial effects of this invention are that the cable storage rack can store all the cables required for the longitudinal movement of the drilling rig, meeting the requirements for the long-span longitudinal cluster well movement of the drilling rig; the elevated folding arm transport bridge can store all the cables required for the lateral movement of the drilling rig, meeting the requirements for the long-span lateral cluster well movement of the drilling rig. During the long-span longitudinal and lateral movement of the drilling rig, no manual intervention in cabling is required. The longitudinal and lateral movements are automatically and seamlessly connected, solving the problem of crane and personnel involvement throughout the entire process in current long-span longitudinal and lateral bidirectional cluster well drilling rig cable systems. This allows for long-span longitudinal and lateral bidirectional cluster well operations at a lower economic cost. The cables are laid once and do not need to be disassembled, significantly reducing the frequency of crane use during drilling operations, lowering manpower and material consumption, and improving movement efficiency; it also effectively reduces the risk of cable scratches and breakage; and it has advantages such as stable and reliable structure, convenient installation and operation, and wide applicability.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1The structure of the cable transport system of the present invention mainly includes a cable storage rack 1, a short extension rack 2, a long extension rack 3, and an elevated folding arm transport bridge 4. To illustrate the technical solution of the present invention, taking a well site layout of 15 wells (5 longitudinal wells and 3 transverse wells) as an example, during the transport of the drilling rig main unit 6 and the vibrating screen tank skid 11, the mud pump unit 9 and the VFD room 10 remain stationary. After the high-pressure manifold 7 passes through the bottom of the short extension rack 2, high-pressure manifold short sections 8 with longitudinal and transverse well spacing lengths are added at different positions to meet the requirements of long-span transport of the drilling rig in both longitudinal and transverse directions.

[0026] Reference Figure 2 The cable storage rack 1 is a frame structure. A guide rail 1 is set on the top of the cable storage rack 1 along the center line. In the initial state, a cable transfer box I 12 is set on the front section of the guide rail 1, and a saddle is set on the middle section of the guide rail 1. An electric winch 13 is installed at the tail end of the cable storage rack 1. A guide rail 2 is set on the top of the short extension rack 2 along the center line, and a guide rail 3 is set on the top of the long extension rack 3 along the center line. Before the transfer work, the two ends of the guide rail 2 are connected to the guide rail 1 and the guide rail 3 respectively, which are called the main guide rail. The saddle moves forward along the main guide rail and the cables are suspended and unfolded in sequence. The high-pressure manifold 7 passes through the gap at the bottom of the short extension rack 2 and is connected to the riser of the drilling rig host 6. Since the longitudinal span of the drilling rig host 6 is large, a connecting beam for suspending the high-pressure manifold 7 is set on the base of the long extension rack 3, which is the same as the longitudinal well spacing length, to increase the load-bearing capacity of the high-pressure manifold 7. Multiple pipe clamps are set on the outside of the two extension racks for installing and fixing the relevant rigid pipes for conveying air, fire water and clean water. During longitudinal movement of the drilling rig, the cable transfer box I12 and the saddle carrying the cable can move back and forth on the connected main guide rail. After the cable is transferred from the cable transfer box I12, it enters the elevated folding arm transport bridge 4, which meets the requirements for large-span lateral movement of the drilling rig.

[0027] Reference Figure 1 , Figure 2 , Figure 3 The structure of the elevated folding arm transport cable tray 4 includes an outer folding arm cable tray 18 and an inner folding arm cable tray 19. The outer folding arm cable tray 18 and the inner folding arm cable tray 19 are hinged end to end by a pin and can rotate and fold around the pin in the horizontal plane, such as... Figure 3 As shown in detail diagram III; a flange sleeve is installed at each end of the elevated articulated boom transfer cable tray 4, and a sleeve support frame 16 is inserted into each flange sleeve. This connection and fixation increases the overall stability of the elevated articulated boom transfer cable tray 4, as shown in detail diagram III. Figure 3As shown in detail I; at the middle of the elevated articulated boom transport bridge 4, that is, at the hinge point between the outer articulated boom bridge 18 and the inner articulated boom bridge 19, a flange is used to connect with the flange of the support frame 17, as shown in detail IV; the bottom of the support frame 17 is provided with universal rollers 14, and the bottom end of the sleeve support frame 16 of the outer articulated boom bridge 18 is also provided with universal rollers 14. The inner articulated boom bridge 19 is fitted into the round hole in the middle of the base connecting bracket 20 near the base. The base connecting bracket 20 is hinged to the drilling rig host 6.

[0028] When the drilling rig host 6 is moved, it relies on the power of the drilling rig host 6 itself and the universal rollers 14 at the bottom of the overhead folding arm moving bridge 4 to change the horizontal hinge angle between the outer folding arm bridge 18 and the inner folding arm bridge 19 to achieve the lateral movement of the drilling rig host 6.

[0029] Reference Figure 4 When the cable storage rack 1 needs to be transported separately, the steel wire rope of the electric winch 13 at the tail end of the cable storage rack 1 is used to retract the saddle and cable junction box I 12, which are used for longitudinal movement of the drilling rig and which are suspended by cables, from the main guide rail to the inside of the guide rail of the cable storage rack 1, so that all the cables required for longitudinal cluster well movement of the drilling rig can be transported together with the cable storage rack 1.

[0030] Reference Figure 5 Disconnect the cable connectors between cable junction box I12 and outer folding arm cable tray 18, and between cable junction box II21 and inner folding arm cable tray 19. Unfasten the flange connection bolts between the elevated folding arm transport cable tray 4 and sleeve support frame 16 and support frame 17. Use external force such as a crane to flip the outer folding arm cable tray 18 so that it is tightly attached to the inner folding arm cable tray 19. This will enable the elevated folding arm transport cable tray 4 and all its cable conduits required for the transverse cluster well transport of the drilling rig to be transported as a whole with the elevated folding arm transport cable tray 4.

[0031] The cable transport system for the large-span longitudinal and transverse cluster drilling rig of this invention includes two methods in actual operation: longitudinal transport and transverse transport, which are described below:

[0032] 1. The working process of the longitudinal relocation method (taking the drilling rig located in the second row of wells in the transverse direction as an example, relocating five wells longitudinally) is implemented according to the following steps:

[0033] Step 1: According to the layout of the wellhead 5 at the drilling site, cable storage rack 1 and short extension rack 2 are arranged sequentially at the front end of VFD room 10, and the guide rails 1 and 2 at the top of cable storage rack 1 and short extension rack 2 are aligned; the high-pressure manifold 7 connecting mud pump group 9 passes through the bottom of short extension rack 2 and reaches drilling rig host 6; the base connecting bracket 20 with fixed sleeve support frame 16 is connected to drilling rig host 6 by a pin shaft, and the elevated folding arm transfer bridge 4 is connected to sleeve support frame 16 and support frame 17 by flanges respectively. The cable led from the electrical control room is transferred through cable transfer box I 12 at the front end of short extension rack 2 and enters elevated folding arm transfer bridge 4, and then through cable transfer box II 21 on drilling rig host 6 before entering the interior of drilling rig host 6. See Figure 3 , Figure 6a ;

[0034] Step 2: Before the drilling rig is prepared for longitudinal movement, firstly, a long extension frame 3 of the same length as the longitudinal well spacing needs to be installed at the front end of the short extension frame 2, and the guide rails 2 and 3 at the top of the two along the center line are connected; disconnect the longitudinal joint of the high pressure manifold 7; secondly, use external force to pull the cable transfer box I12 at the front end of the short extension frame 2 and the saddle for suspending the cable forward along the guide rail 3 of the long extension frame 3.

[0035] When the drilling rig is moved longitudinally to the new wellhead, a high-pressure manifold short section 8 of the same length as the longitudinal well spacing is installed at the longitudinal joint of the high-pressure manifold 7 to connect the pipelines and cables between the various components of the drilling rig host 6 (see 6b), thus completing the movement of one longitudinal well spacing.

[0036] Step 3: Before each relocation, install a new long extension frame 3 of equal length to the longitudinal well spacing at the front end of the long extension frame 3 of the suspended cable junction box I12. Repeat the above steps to complete the continuous longitudinal relocation of the drilling rig to the five well locations. See Figure 6c ;

[0037] During the longitudinal movement of the drilling rig, the universal rollers 14 at the bottom of the overhead folding arm transport bridge 4 are driven by the power of the drilling rig main unit 6 or by external force to move it longitudinally forward. At this time, the angle between the outer folding arm bridge 18 and the inner folding arm bridge 19 remains basically unchanged. When the drilling rig is moved longitudinally to the new well position, the two ends of the cable in the overhead folding arm transport bridge 4 are connected to the cable transfer box I12 and the cable transfer box II21 respectively, and the rig is completed.

[0038] 2. The working process of the lateral transport method (taking the drilling rig located in the fourth column of wells longitudinally as an example, and transporting three wells laterally) is implemented according to the following steps:

[0039] Step 1: Based on the layout of the wellhead 5 at the drilling site, arrange the cable storage rack 1, short extension rack 2, and two long extension racks 3 sequentially at the front end of the VFD room 10, and connect them with guide rails 1, 2, and 3 positioned along the center line at the top of the three to form the main guide rail; the high-pressure manifold 7 led from the mud pump group 9 passes through the bottom of the short extension rack 2 to reach the drilling rig host 6; the base connecting bracket 20, which is fixed with a sleeve support frame 16, is connected to the drilling rig host 6 by a pin shaft; the elevated folding arm transport cable tray 4 is connected to the sleeve support frame 16 and the support frame 17 by flanges respectively; the cable led from the electrical control room passes through the cable transfer box I12 at the front end of the longest extension rack 3 and enters the elevated folding arm transport cable tray 4, then passes through the cable transfer box II21 on the drilling rig host 6 and enters the interior of the drilling rig host 6, see Figure 3 , Figure 6d ;

[0040] Step 2: Before the drilling rig is moved laterally, first, keep the cable junction box I12 at the end of the long extension frame 3 at the front end and disconnect the lateral joint of the high-pressure manifold 7; second, use the drilling rig main unit 6's own power or auxiliary external force to pull the elevated folding arm moving bridge 4 to the required angle of deployment.

[0041] When the drilling rig is moved laterally to the new well location, a high-pressure manifold short section 8, with a length equal to the lateral well spacing, is installed at the lateral joint of the high-pressure manifold 7 to connect the pipelines and cables between the various components of the drilling rig main unit 6. (See...) Figure 6e The drilling rig was moved laterally to complete the lateral movement of a high-pressure manifold section 8.

[0042] Step 3: Keeping the cable junction box I12 at the end of the foremost long extension frame 3, repeat the above steps to complete the multiple lateral relocations of the drilling rig to the three well sites. See Figure 6f That's it.
