Embodiment

[0046] This embodiment relates to a new type of mechanical wax removal winch used in the petroleum field. It is mainly composed of a power system, a transmission system, a motion conversion system, and a rope counting system connected in sequence. The motion conversion system is connected with a control system. And the power system, transmission system, motion conversion system, rope counting system and control system are all connected with the same parameter display system.

[0047] The power system is mainly composed of an anti-explosion AC motor with stepless speed regulation in forward and reverse directions.

[0048] The transmission system is mainly composed of a belt transmission and a gear transmission with two stages of variable speed transmission.

[0049] The motion conversion system is mainly composed of a drum and a wire rope.

[0050] The control system is mainly composed of a set of clutch, belt hub brake and hand brake.

[0051] The rope counting system is ma...

Abstract

The invention discloses a novel mechanical paraffin cleaning hoist applied to the petroleum field. The novel mechanical paraffin cleaning hoist is mainly formed by a power system, a transmission system, a motion conversion system and a rope arrangement notation system which are sequentially connected. A control system is connected onto the motion conversion system. The power system, the transmission system, the motion conversion system, the rope arrangement notation system and the control system are connected with the same parameter display system. The novel mechanical paraffin cleaning hoist is small in volume, compact in structure, stable in transmission and reliable in braking, and has the function of tension, depth and speed display.

Description

technical field [0001] The invention relates to a novel mechanical wax removal winch applied in the petroleum field. Background technique [0002] Many oilfields in my country have high wax content and severe wax deposition, resulting in smaller oil flow channels and increased resistance in oil wells, seriously affecting oil well production. Periodic wax removal is required to ensure smooth production. For example, Well Shilong 16 of North Sichuan Gas Production Plant of Southwest Oil and Gas Company needs to remove wax every other day to ensure smooth production. [0003] Wax removal winch is an effective tool for self-flow well wax removal. The mechanical wax removal winch is used for wax removal, the wax removal depth is shallow, and the wax removal intensity is low. In the early stage of self-flowing well, the oil-gas ratio is low, the amount of wax deposition is small, and the distance between the wax deposition point and the wellhead is 50-100 meters, which can meet ...
