Description

Technical Field

[0001] This invention relates to the field of oil and gas drilling and equipment technology. More specifically, this invention relates to an automated drilling string handling system and method for dual-sided operations. Background Technology

[0002] With the development of automation and information technology, oil and gas drilling and production operations are increasingly adopting automated machinery and intelligent control to replace traditional manual operations, reducing the labor intensity of workers, such as automatic pipe-laying devices on drilling rigs. Currently, automatic pipe-laying devices are widely used on drilling rigs and are becoming increasingly mature in processes such as drill string erection, drill string removal, and tripping, playing a crucial role. However, because the execution and accuracy of automated equipment rely on sensors, and the harsh environment, numerous construction steps, and large number of sensor parameters in oil and gas drilling operations result in low accuracy, the operational efficiency of automated pipe-laying devices is limited, thus affecting the overall drilling operation efficiency.

[0003] There are currently several main drilling string handling methods, which can be categorized by structure into push-support, suspended, and lift-up types; and by operation method into offline and conventional types. Offline methods allow for normal drilling operations while drill pipe construction and removal are being carried out simultaneously, meaning the string handling does not occupy the wellhead and does not affect the normal operation of the wellhead and main and traveling booms, thus saving overall drilling time and improving well construction efficiency. However, this method only achieves offline drill pipe handling; casing is still run in a traditional single-pipe manner, and the efficiency of casing and casing string handling is not improved.

[0004] The main problem with the existing technology is that the current solution only realizes the offline processing of drill pipe, while the casing is still run in the traditional single-pipe manner. The casing running and casing string processing are still traditional manual operations, and the casing can only be transported and processed after drilling is completed. The labor intensity and time efficiency of the operation have not been improved. Summary of the Invention

[0005] One objective of this invention is to provide an automated drilling string processing system and method for dual-sided operations. Based on current drilling string processing methods, this invention proposes a dual-sided automated processing system and method for casing string processing, which can both automatically establish casing foundations offline and automatically run casing, as well as automatically process drill pipe foundations and automatically trip drill bits.

Therefore, they should not be construed as limitations on this invention.

[0022] like Figures 1 to 12 As shown, this invention provides a dual-face drilling string automatic processing system, including an automatic drill pipe processing system and an offline automatic casing processing system, which are located on opposite sides of the derrick 16, forming a dual-face working surface: a drill pipe working surface and a casing working surface. The drill pipe working surface is located on the rear side of the derrick and is equipped with a drill string platform and a drill platform. The drill platform is equipped with a stand-up box for placing drill pipes and drill collars. During drilling, the automatic drill pipe processing system is used to store and retrieve drill string, and to perform drill string tripping and drill string running. The casing working surface is located on the front side of the derrick and is equipped with a casing platform and a drill platform. The drill platform is equipped with a casing stand-up box and a casing rodhole for assembling casing stand-up boxes and placing casing stands. During cementing, the offline automatic casing processing system is used to store and retrieve casing and to run casing.

[0023] The dual-face drilling string automatic processing system has two automatic processing systems: an automatic drill pipe processing system and an offline automatic casing processing system. These two systems are installed on opposite sides of the derrick, respectively, to automatically process the drill pipe and casing. Figure 10 As shown, the left side is the drill pipe automatic processing system, and the right side is the casing offline automatic processing system.

[0024] The drill pipe automatic handling system corresponding to the drill pipe working face includes: a main traveling crane system 18, a drill pipe hydraulic lifting chuck 21, hydraulic power slips, a drill pipe second-level platform robot 15, a power drill pipe second-level platform 14, a drill pipe drilling platform robot 13, a drill pipe iron drill 12, and an integrated control system. The drill tool second-level platform robot is set on the power second-level platform and is linked with the drilling platform robot to synchronously clamp and hold the drill pipe, realizing the automatic transfer of the drill pipe column 10 between the root zone and the wellhead; the drill pipe iron drill 12 is used for operations in the rodhole and wellhead and for uncoupling the drill pipe; the hydraulic drill pipe lifting chuck is installed on the top drive 19 lifting ring 20 of the main traveling crane, and both it and the hydraulic power slips are driven and controlled by the integrated control system; the main traveling crane system is used for lifting and lowering the tubing string. The drilling tool's second-level platform manipulator includes a lifting column installed on the second-level platform structure. The lifting trolley, along with the traveling rail and the monkey platform, moves up and down along the lifting column. The traveling trolley moves back and forth on the traveling rail extended from the lifting trolley. The rotary drive on the traveling trolley drives the telescopic arm of the manipulator to rotate ±90°. The telescopic arm drives the clamp assembly to extend and retract, and the clamp suspends the drill pipe string and moves.

[0025] It also includes a power catwalk 9 and a hydraulic station. The drill pipe automatic handling system and the casing offline automatic handling system share one power catwalk and hydraulic station. A buffer manipulator is installed at the end of the power catwalk to assist in turning the tubing string from a horizontal to a vertical position and to push the tubing string from the wellhead to the catwalk for ejection. The hydraulic station is used to drive the various actuators of the power catwalk and the manipulator.

[0026] The casing offline automatic processing system corresponding to the casing working face includes: an auxiliary traveling crane system 1, a casing second-level platform robot 2, a powered casing second-level platform 3, a casing drilling platform robot 7, a casing iron drill 5, a casing hydraulic lifting clamp, a casing powered rat hole 6, a casing support robot 8, and an integrated control system. The auxiliary traveling crane system includes an auxiliary traveling beam assembly, including an auxiliary traveling crane beam 22. A second-level platform robot is installed below the auxiliary traveling beam assembly, which is lifted and lowered along the auxiliary traveling crane guide rail 17 via an auxiliary traveling crane lifting electric winch 11. The bottom of the second-level platform robot is equipped with a flip-up gripper for clamping and lifting the casing column 4. The casing second-level platform robot and the casing drilling platform robot work together to synchronously suspend and move the casing. The casing powered rat hole is placed in the middle of the casing root area and below the drilling platform, used to center and clamp the casing column, maintaining the stability of the casing joint. The integrated control system is used to control the automated operation of each device. It consists of an electric winch for lifting the auxiliary traveling beam assembly and a robotic arm assembly.

[0027] During drilling operations, the upper and lower manipulators and auxiliary traveling block system at the casing working face can operate independently. The casing power rodhole and casing second-level platform are used to automatically establish the double casing string in advance. This allows for direct casing running after drilling is completed, eliminating the need to transport casings one by one to the drilling platform for single-string running. The biggest advantage of this method is that drilling operations and casing string preparation are carried out simultaneously, rather than waiting until drilling is finished. Furthermore, by connecting the casings into a double casing string beforehand, the efficiency of running a single casing string is doubled. Combined with offline casing string establishment, this significantly improves the efficiency of casing running operations, especially in deep well operations. Automated equipment such as casing string manipulators are used to grab the casing string and deliver it to the wellhead. The casing driller then uses a casing iron drill to add and remove the couplings, achieving automated and rapid casing running operations.

[0028] This invention also discloses an automatic drilling string processing method for dual-face operations. The process of establishing a drill string using an automatic drill string processing system corresponding to the drill string working face includes the following steps: Step 1: The power catwalk secondary transfer arm extends and horizontally transports the drill string to the wellhead; Step 2: The hydraulic slips are used to secure the tubing string.

Step 5: The main traveling crane descends, the hydraulic hoist of the drill pipe lowers the second drill bit and engages it with the first drill bit, and the drill pipe iron driller engages the upper engagement; Step 6: After the upper clamp is completed, the hydraulic slip is released, the main traveling crane descends, the drill pipe hydraulic clamp lowers the drill string to the wellhead seat, and at the same time the power catwalk transports the third drill string; Step 7: Raise the third drill string in the same manner as above, and center the pipe with the pipe-supporting robot. Step 8: The main traveling crane descends, the drill pipe hydraulic lifting clamp lowers the third drill string to the wellhead for connection, and the drill pipe iron driller performs the upper connection; Step 9: After the upper clamp is completed, release the clamp, lift the hydraulic drill pipe hoist to the drill platform, and simultaneously move the second-level platform manipulator and the drill platform manipulator to the wellhead to grab the tubing string. Step 10: The hydraulic drill pipe clamp is opened, and the second-level platform robot and the drill platform robot simultaneously grab the column formed by the three pipe columns and move it synchronously to the finger beam and the root box in the root area on the drill platform to complete the establishment of one column. Step 11: Repeat the above steps to complete the construction of multiple columns.

The second-level platform manipulator and the drilling platform manipulator move synchronously to send the next column from the finger beam area to the wellhead for drilling the next column.

[0030] The process of pulling the drill string out of the hole includes the following steps: Step 1: The main traveling hoist system lifts the column from the wellhead to the drilling platform and then uses hydraulic slips to engage the drill pipe. The drill pipe is then extended to the wellhead for connection. Step 2: The second-level platform manipulator and the drilling platform manipulator move synchronously to the wellhead to grab the column, the hydraulic drill pipe hoist opens, and the main traveling hoist system retracts to avoid the space and lowers the column. Step 3: The second-floor robot and the drilling platform robot move synchronously to send the column into the finger beam and root zone; Step 4: The hydraulic drill pipe clamp engages with the next column, the main traveling crane system lifts up, and the next column is started for drilling.

Step 2: The second-level platform manipulator and the drilling platform manipulator move synchronously to the wellhead to grab the column, the hydraulic drill pipe hoist opens, and the main traveling hoist system retracts to avoid the space and lowers the column. Step 3: The second-floor robot and the drilling platform robot move synchronously to send the column into the finger beam and root zone; Step 4: The hydraulic drill pipe clamp engages with the next column, the main traveling crane system lifts up, and the next column is started for drilling.

8. The automatic drilling string handling method for double-sided operations as described in claim 5, characterized in that, The process of establishing casing support using an offline automated casing processing system includes the following steps: Step 1: The power cat path delivers the first casing to the casing mouse hole; Step 2: The casing is picked up by the robotic arm on the second-level platform, and the auxiliary floating hoist system lifts the casing. The casing is then straightened and aligned with the mouse hole by the assistance of the pipe-supporting robotic arm. Step 3: The auxiliary swing system lowers the first sleeve into the mouse hole and secures it. Step 4: Transport the second casing in the same manner as above, lift it up and fasten it with the first casing, and the driller extends into the rat hole to fasten the casing. Step 5: Lift the casing column. The drilling platform robot and the second-floor robot move synchronously to send the casing column into the casing finger beam and root zone.

9. The automatic drilling string handling method for double-sided operations as described in claim 8, characterized in that, The process of installing casing and establishing support includes the following steps: Step 1: The drilling platform robot and the second-level platform robot work together to grab a casing anchor from the casing finger beam and anchor area. Step 2: The auxiliary traveling hoist system lifts up, and the drilling platform manipulator and the second-level platform manipulator work together to send the casing stand to the wellhead. After the lower part of the casing stand is engaged with the wellhead casing, it is handed over to the hydraulic casing hoist. Step 3: The drilling platform manipulator and the second-level platform manipulator on the casing working face retract, and the casing driller extends to the wellhead for connection. Step 4: Open the hydraulic slips, lower the main traveling crane, and lower the casing into the well.
