Continuous pipe working device and rotation speed control method of same

Abstract

The invention discloses a continuous pipe working device comprising an injection head, a continuous pipe, a vehicle body, a roller arranged on the vehicle body, a roller driving mechanism, and a rack pipe mechanism. One end of the continuous pipe is connected with the injection head, while the other end of the continuous pipe is fixed on the roller after penetrating through the rack pipe mechanism. The roller is used for winding the continuous pipe and can be driven by the roller driving mechanism to rotate. The rack pipe mechanism can guide the continuous pipe to move in the axial direction of the roller. The axis of the roller is parallel to the length direction of the vehicle body. As the axis direction of the roller of the continuous pipe working device is parallel to the length direction of the vehicle body, the length of the roller is increased and then the length of the continuous pipe wound on the roller is increased, therefore the working depth of the continuous pipe working device is increased.

Description

technical field The invention relates to an operating device used in oil and natural gas development, workover, drilling and other constructions, in particular to a coiled tubing operating device. Background technique At present, the use of coiled tubing for oil and gas development and workover, drilling, and fracturing stimulation operations has gradually become popular. Coiled tubing replaces drill pipes for oil and natural gas operations, which can avoid disassembly and assembly of drill pipes, thereby reducing downhole accidents such as joint disconnection, reducing labor intensity of workers, saving operating time and improving operating efficiency. Existing coiled tubing devices usually include a car body, drum, hydraulic station, injection head, etc., wherein the car body is used to carry the drum, hydraulic station and injection head. The drum is used to wind the coiled tubing, and the axis of the drum is perpendicular to the long direction of the vehicle body. Ho...

Problems solved by technology

However, due to factors such as road height restrictions and width restrictions, the length and diameter of the drum are limited. Therefore, the length of the continuous pipe wound on it is also limited, thus affecting the working depth.
