Description

Technical Field

[0001] This invention belongs to the technical field of oil drilling and production auxiliary equipment, and relates to a high-level horizontal power catwalk with lifting function. This invention also relates to a bidirectional drilling tool transport method. Background Technology

[0002] In offshore drilling platforms, the bidirectional transport of drill strings between the deck piping area and the drilling platform has long been a problem, affecting not only drill string transport efficiency and drilling efficiency but also posing a constant threat to equipment and personnel safety. Therefore, it is imperative to thoroughly study and resolve this issue.

[0003] In offshore drilling operations, the bidirectional transport of drill strings between the deck pipe stacking area and the drilling platform generally employs conventional pneumatic winch transport, pull / lift-type powered catwalk transport, or horizontal powered catwalk + platform crane transport. All these methods have varying degrees of shortcomings: conventional pneumatic winch transport carries a high risk of drill string slippage, frequently resulting in injuries and posing significant safety risks; pull-type powered catwalks are located far from the wellhead, occupying a large area on the offshore platform and cannot be fully secured to the T-shaped structure in the pipe stacking area, presenting certain operational risks; existing horizontal powered catwalks specifically designed for offshore platforms, with automatic drill string transport and support functions, are suitable for low-level drilling platforms but lack the ability to lift drill strings from higher levels, thus failing to achieve automated bidirectional transport of drill strings between the deck pipe stacking area and the high-level drilling platform; existing pull / lift-type powered catwalks require driving components heavier than the transported pipe string up and down, resulting in high energy consumption.

[0004] In summary, existing technologies suffer from high energy consumption in drill bit delivery, low safety, and poor applicability. Summary of the Invention

[0005] The purpose of this invention is to provide a high-level horizontal power catwalk with lifting function, which solves the problems of high energy consumption, low safety and poor applicability of drill bit transportation in the prior art.

[0006] Another object of the present invention is to provide a bidirectional drilling tool delivery method.

[0007] The technical solution adopted in this invention is a high-level horizontal power catwalk with lifting function, including a first support assembly, several deck T-shaped structural components fixedly connected to the bottom of the first support assembly, a second support assembly connected to the first support assembly via a pin shaft, the second support assembly being fixedly connected to the side wall of the high-level drill platform via a connecting seat assembly, a pulley assembly being provided on the second support assembly, and several drill string lifting devices being provided between the first support assembly and the second support assembly.

[0008] The invention is further characterized by: The drill string lifting device and the second support assembly are hinged together by a pin. The drill string lifting device includes a guide rail, and a trolley is slidably arranged in the guide rail. One end of the trolley is hinged to an adjustment device through a double-hole ear plate, and the other end of the trolley is hinged to an integrated loading and unloading arm through a connecting pin. The integrated loading and unloading arm is hinged to the adjustment device.

[0009] A lower sprocket shaft is provided at one end of the guide rail, and an upper sprocket shaft is provided at the other end. The lower sprocket shaft is fixed inside the guide rail by a tensioning mechanism, which is hinged to the guide rail. The upper sprocket shaft is connected to a drive mechanism, which is fixed to one end of the guide rail. A roller chain is provided between the lower sprocket shaft and the upper sprocket shaft, and the roller chain is fixed to the trolley. Limit blocks are provided at both ends of the guide rail.

[0010] One end of the integrated loading and unloading arm is equipped with a fixed baffle, and the other end is hinged to an automatic tilting baffle and a hydraulic cylinder via a pin. The automatic tilting baffle has a V-shaped structure and is hinged to the hydraulic cylinder via a pin.

[0011] The trolley assembly includes a trolley frame, a drive assembly in the middle of the trolley frame, a roller assembly connected to the drive assembly, the roller assembly being fitted with a second support assembly, a robotic arm and a lifting arm at the end of the trolley frame, a small trolley slidably mounted on the trolley frame, the small trolley being driven by a hydraulic motor; a first kick-out plate and a second kick-out plate are mounted on the trolley frame, the first kick-out plate and the second kick-out plate being hinged together.

[0012] The first support assembly is attached to the deck T-shaped structural member on one side, and a first pressure plate is attached to the other side. A second pressure plate is attached to the side of the deck T-shaped structural member away from the first support assembly. The first pressure plate, the first support assembly, the deck T-shaped structural member and the second pressure plate are fixedly connected by bolts.

[0013] Another technical solution adopted in this invention is a bidirectional drilling tool delivery method, comprising the following steps: The drill string is transported from the deck pipe stacking area to the high-level drilling platform via a high-level horizontal power catwalk with lifting function. The drill string is transported from the high-level drilling platform to the deck pipe laying area via a high-level horizontal power catwalk with lifting capabilities.

[0014] Another feature of the technical solution of the present invention is that: Transporting the drill string from the deck pipe stacking area to the high-level drilling platform via a high-level horizontal power catwalk with lifting capabilities includes the following steps: A1. Adjust the trolley in the drill string lifting device to a low position, adjust the integrated loading and unloading arm to an inward tilting posture, and adjust the automatic tilting baffle to a falling position. A2. Use a crane to lift the drill string from the deck pipe laying area into the integrated loading and unloading arm, adjust the automatic tilting baffle to the lifting state, start the drive mechanism, and then the roller chain drives the trolley to move in the guide rail. When the integrated loading and unloading arm reaches the highest limit block, it stops moving. A3. Lower the integrated loading and unloading arm, the drill bit rolls into the first kick plate and stops inside the first kick plate. Adjust the first kick plate to flip inward and then adjust the second kick plate to flip inward. After the drill bit falls into the second kick plate, lower the second kick plate. The drill bit enters the V-groove on the trolley assembly and stops at the V-groove. A4. Move the trolley assembly to the side of the second support assembly near the high-level drilling platform. Adjust the position of the drill bit using the small trolley. After adjustment, one end of the drill bit is on the small trolley and the other end is on the lifting arm. Adjust the height of the drill bit using the lifting arm and, in conjunction with the robotic arm, adjust the drill bit to a vertical position. A5. The drilling tools are lifted by a crane and transported to the high-level drilling platform, completing the transport process.

[0015] Transporting the drill string from the high-level drilling platform to the deck pipe stacking area via a high-level horizontal power catwalk with lifting capabilities includes the following steps: B1. Adjust the integrated loading and unloading arm to an outward tilt position and adjust the automatic tilting baffle to the lifting position; B2. The drill string is lifted from the high drilling platform by a crane and then lowered onto the trolley assembly. The small trolley moves away from the wellhead. When the crane lowers the drill string, one end of the drill string is locked to the crane, and the other end is against but does not detach from the small trolley. B3. Operate the robotic arm and lifting arm to adjust the height of the drill string, and work with the crane to adjust the drill string to a horizontal position; B4. The first kick-out plate flips outward, the second kick-out plate flips inward and then descends, the drill string rolls into the integrated loading and unloading arm and stops inside the first kick-out plate; the integrated loading and unloading arm rises until the drill string rolls into the integrated loading and unloading arm and stops inside the automatic tilting baffle, and then the integrated loading and unloading arm descends to the lowest limit and stops moving. B5. Adjust the automatic tilting baffle to the lowering position, and use a crane to transport the drill string to the deck pipe laying area. The delivery is complete.

[0016] When the integrated loading and unloading arm is adjusted to an inward tilt position, the position of the automatic flip baffle is higher than the position of the fixed baffle on the integrated loading and unloading arm. When the integrated loading and unloading arm is adjusted to an outward tilt position, the position of the automatic flip baffle is lower than the position of the fixed baffle on the integrated loading and unloading arm; When the automatic tilting baffle is adjusted to the lifting position, the hydraulic cylinder lifts up to support the automatic tilting baffle to rise. When the automatic tilting baffle is adjusted to the falling position, the hydraulic cylinder retracts, causing the automatic tilting baffle to fall.

[0017] The beneficial effects of this invention are as follows: This invention is used to realize the transportation of equipment between the deck pipe laying area and the high-level drilling platform. The bottom of this invention is fixed to the T-shaped structural component of the deck, ensuring the overall structural stability and reliability. In the drill string lifting device, the angle of the integrated loading and unloading arm is adjusted by an adjustment device, allowing the drill string to roll freely into or out of the integrated loading and unloading arm, meeting different needs for upward and downward transportation of the drill string. The drill string lifting device is equipped with an automatic flip-over baffle structure to solve the problem of manually installing stop pins during drill string transportation. After the drill string is lifted to a high position by the drill string lifting device, it is transported to the drilling platform through the trolley assembly, realizing bidirectional transportation of the drill string between the ground pipe laying area and the high-level working platform of the catwalk. The overall structure is compact, and the lifting and lowering are stable and controllable, making it suitable for offshore platforms. Attached Figure Description
