Embodiment

[0046] This embodiment relates to a mechanical wax removal winch used in the petroleum field, which is mainly composed of a power system, a transmission system, a motion conversion system, and a rope counting system connected in sequence, and a brake control system is connected to the motion conversion 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 brake control system is mainly composed of a set of clutch, belt hub brake and hand brake.

[0051] The rope counting system is mainly composed of counting wheels and pressing wheels.

[0052] The working principle of the present invention is as follows:

[0053] After the power of the mech...

Abstract

The invention discloses a mechanical paraffin cleaning hoist applied to the field of petroleum. The mechanical paraffin cleaning hoist is mainly formed by a power system, a transmission system, a movement conversion system and a leg along counting system which are sequentially connected. The movement conversion system is connected with a brake control system. The mechanical paraffin cleaning hoist is simple and compact in structure, light in weight, large in transmission impact, low in brake reliability and small in size due to the fact that a conventional transmission and brake system is adopted.

Description

technical field [0001] The invention relates to a mechanical wax removal winch used 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 the wax r...
