Description

Technical Field

[0001] This invention belongs to the technical field of oil and gas drilling and production equipment, and relates to a system for constructing the anchorage of an oil drilling rig that facilitates the transportation of tubing strings. This invention also relates to a method for constructing the anchorage. Background Technology

[0002] In a conventional oil drilling rig stand-up construction system, the second-level platform, stand-up box, and tubing delivery channel are all located on the same side of the wellhead. The tubing includes drill pipe, casing, and drill collars. The tubing delivery channel refers to the passage through which the tubing is transported from both sides of the catwalk to the rat hole or wellhead on the drilling platform. Depending on the catwalk configuration, there are two arrangements: When a powered catwalk is configured, the tubing located on both sides of the powered catwalk is transported to the drilling platform through the catwalk, and then transported to the rat hole or wellhead from above the middle channel of the stand-up box; When a conventional catwalk and ramp are configured, the tubing is first manually pushed from both sides of the conventional catwalk into the conventional catwalk, and then an auxiliary winch is used to drag the tubing along the upper surface of the conventional catwalk and ramp to the drilling platform, and then transported to the rat hole or wellhead from above the middle channel of the stand-up box.

[0003] The existing stand-up assembly system for oil drilling rigs has three problems: First, the stand-up assembly box must be wide enough to meet the stand-up assembly requirements of the drilling rig, and a personnel passage must also be set up on the side of the stand-up assembly box closest to the catwalk. Therefore, the distance between the edge of the catwalk on the drilling rig and the wellhead is too large, and the catwalk needs to be raised to a high position to transport the tubing, resulting in low efficiency in tubing transport. Second, the drilling rig robotic arm needs to be equipped with a clearance track. When loading or unloading tubing, the drilling rig robotic arm needs to move along the clearance track to the clearance position. The clearance track design of the drilling rig robotic arm is complex, and the clearance operation is time-consuming and labor-intensive, affecting the transport of tubing. Third, when the stand-up assembly is full, the middle passage is blocked, affecting the loading and unloading of tubing onto the drilling rig surface. Summary of the Invention

[0004] The purpose of this invention is to provide an oil drilling rig support construction system that facilitates the transportation of tubing, thus solving the problem of limited access to the drilling platform for tubing in the prior art.

[0005] Another object of the present invention is to provide a method for constructing a root system.

[0006] The first technical solution adopted in this invention is an oil drilling rig stand-up construction system that facilitates pipe string transportation, including a base, a drilling platform on the base, a derrick on the drilling platform, a pipe-gripping manipulator on one side of the derrick, a second-tier platform on the other side, a wellhead on the drilling platform located at the bottom of the derrick, a stand-up box located directly opposite the drilling platform and the second-tier platform, a first and a second mouse hole located on the side of the wellhead away from the stand-up box, a steel driller located on the side of the first mouse hole, a control system located on the side of the steel driller, a powered catwalk connecting the drilling platform and the pipe-gripping manipulator, a drilling platform manipulator on the stand-up box, and the control system electrically connected to the pipe-gripping manipulator, the drilling platform manipulator, the steel driller, and the powered catwalk.

[0007] The first technical solution of this invention is also characterized by:

[0008] A third mouse hole is located on the side of the wellhead away from the power cat passage.

[0009] The derrick can be an open derrick at both the front and back, a portal derrick, or an A-type derrick.

[0010] The drilling rig includes a first box body, a middle channel on one side of the first box body, the projections of the middle channel, the wellhead, and the power cat track in the horizontal direction are on the same straight line, a second box body is set on the side of the middle channel away from the first box body, and a drilling rig robot arm is set on the middle channel.

[0011] The second technical solution adopted in this invention is an oil drilling rig stand-up construction system that facilitates pipe string transportation, including a base, a drilling platform on the base, a derrick on the drilling platform, a pipe-gripping manipulator on one side of the derrick, two-tiered platforms on both sides of the derrick, a wellhead on the drilling platform located at the bottom of the derrick, a stand-up box located directly opposite the drilling platform and the two-tiered platform, a first and a second mouse hole located on the side of the wellhead away from the stand-up box, a steel driller located on the side of the first mouse hole, a control system located on the side of the steel driller, a powered catwalk connecting the drilling platform and the pipe-gripping manipulator, a drilling platform manipulator on the stand-up box, and the control system electrically connected to the pipe-gripping manipulator, the drilling platform manipulator, the steel driller, and the powered catwalk.

[0012] The second technical solution of the present invention is further characterized by:

[0013] A third mouse hole is located on the side of the wellhead away from the power cat passage.

[0014] The derrick can be an open derrick at both the front and back, a portal derrick, or an A-type derrick.

[0015] The drilling rig includes a first box body, a middle channel on one side of the first box body, the projections of the middle channel, the wellhead, and the power cat track in the horizontal direction are on the same straight line, a second box body is set on the side of the middle channel away from the first box body, and a drilling rig robot arm is set on the middle channel.

[0016] The third technical solution adopted in this invention is a root-supported construction method, which is implemented according to the following steps:

[0017] Step 1: Use the control system to send the three drill pipes from the power catwalk to the drilling platform;

[0018] Step 2: Control the pipe-grabbing robot to send the first drill rod into the first mouse hole, send the second drill rod into the second mouse hole, and then send the third drill rod above the first mouse hole. Connect the first drill rod and the third drill rod with the iron driller to form a double drill rod. Then send the double drill rod above the second mouse hole and connect the double drill rod to the second drill rod with the iron driller to form a vertical drill rod.

[0019] Step 3: The control system enables the pipe-grabbing robot to grab the standpipe and the drilling platform robot to support it, and then the standpipe is moved and placed into the second-level platform and the standpipe box.

[0020] The beneficial effects of this invention are:

[0021] Compared with existing technologies, the oil drilling rig stand-up assembly system of this invention, which facilitates tubing transport, has the stand-up assembly box and the power catwalk located on opposite sides of the wellhead when only one stand-up assembly box is configured. This reduces the size of the drill platform side near the power catwalk, solving the problem of low work efficiency caused by the need to lift the tubing to a higher position when transporting it on the upper section of the power catwalk. Furthermore, the stand-up assembly box is not on the tubing transport channel during drill string ejection, and the drill platform robot installed in the middle channel of the stand-up assembly box is also not on the tubing transport channel during drill string ejection. Therefore, the drill platform robot does not need to be designed to avoid obstruction. Although the middle channel may be blocked after the stand-up assembly is deployed, the upper and lower drill platform surfaces of the tubing will not be affected because the middle channel and the power catwalk are located on opposite sides of the wellhead. When two stand-up assembly boxes are configured, the size of the stand-up assembly box on the side where the power catwalk is located can be reduced, while the size of the drill platform side near the power catwalk can also be reduced, achieving the same effect as configuring a single stand-up assembly box.
