Description

Technical Field

[0001] The invention relates to the technical field of oilfield drilling and repairing equipment, and in particular to an automated drilling system for a drilling rig using a three-level length drill rod. Background Art

[0002] Conventional truck-mounted drilling rigs use an inclined derrick for operation. When the derrick is under load, the elastic deformation of the derrick and the guy rope will cause the center of the wellhead to shift, affecting the safe operation of the traveling hoist system and making it impossible to use automated tools. At the same time, conventional drilling rigs use a two-story platform, and derrick workers must work at high altitudes, posing a safety risk. For this reason, a drilling rig is proposed that uses an upright derrick, eliminates the two-story platform, and uses automated tools to complete the operation. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a super single-root drilling rig automated drilling system for controlling the collaborative work among various automated equipment, ensuring the regional safety of each tool in the working space, coordinating the various tools to operate in parallel as much as possible during the operation, and ensuring the efficiency of the entire operation process.

[0004] The technical solution of the present invention is as follows: Equipped with hydraulic drill rod box, power catwalk, integrated top drive, hydraulic elevator, translation track roughneck, pneumatic slips and other automated tools, driller integrated control system, single driller operation is realized. It is divided into automatic drilling operation and automatic drilling operation.

[0005] 1. The hydraulic drill rod box is a rectangular hollow box-type truss structure. The middle space is used to store multiple layers of drill rods. A lifting lever is set near each end of the box. The drill rods are placed on the two lifting levers. The levers are lowered or raised by the extension and retraction of the hydraulic cylinder.

[0006] 2. The power catwalk adopts variable link lifting technology and full stroke precision positioning technology of the front lifting cylinder to adapt to multi-gear drilling platforms. The power catwalk has local and remote wireless operation functions and is designed with an operating program so that operators can monitor and control the operation of the equipment in real time.

[0007] 3. The traveling and hoisting integrated top drive is integrated with the traveling and hoisting system and can be lifted and moved together with the derrick. The operating system is integrated into the driller's integrated control system.

[0008] 4. The side-opening hydraulic elevator adopts hydraulic remote control for opening, closing and safety locking. The sensor detects whether the elevator is closed. The elevator can realize the two-way automatic flipping function to achieve stand docking at high altitude and single root grabbing at low position.

[0009] 5. The working tongs of the translation track roughneck can rotate at a certain angle relative to the back-up tongs, thereby completing the tightening and loosening of the pipe column joint threads. The spinner is driven by a hydraulic motor to drive two sets of rollers on the left and right to complete the screwing in and out of the pipe column threads.

[0010] 6. The pneumatic slips can control the cylinder to move up and down to drive the slip body to rise and fall, so as to release and clamp the drilling tool.

[0011] 7. The driller integrated control system is configured in the driller's room, and the drilling operation can be completed by "one-key operation" through the linkage of multiple devices.

[0012] The beneficial effects of the present invention are:

[0013] 1. The integrated control system enables the driller to operate the winch, top drive, iron roughneck, hydraulic elevator, power slips, power catwalk, etc., reducing the number of personnel.

[0014] 2. Remove the second-floor platform, cancel the derrick workers and high-altitude operations, and improve the inherent safety of the drilling rig. Apply automation tools to reduce the risk of personnel working at the wellhead.

[0015] 3. Drilling tool storage, upper and lower drilling platforms, and tension buckles are performed by automated tools, reducing the labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS
