Problems solved by technology

[0002] The pumping units used in oil field production include beam pumping units and hydraulic shaft pumping units. Traditional pumping units are widely used in various oil fields at home and abroad due to their mature technology and reliable performance. However, various traditional pumping units The phenomenon of not reaching full load (controlled pumping) generally occurs during oil production, which increases the consumption per ton of liquid and cannot effectively control the cost of oil production

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention will be further described:

[0022] As shown in the figure, the present invention proposes an intelligent soft-rod pumping unit, which includes a motor 1, a transmission device and a driven wheel; the transmission device includes a power gear 4, a first driven gear 8, a second Driven gear 7 and drive shaft 5, the first driven shaft 9 and the second driven shaft 10 that are arranged in parallel; The driven wheel includes the first driven wheel 11 and the second driven wheel 12;

[0023] The output end of the motor 1 is connected to the output gear 3 through the reducer 2. The output gear 3 meshes with the power gear 4. The power gear 4 is set on the drive shaft 5 to drive the drive shaft 5 to rotate. The drive shaft 5 is also provided with a power output gear 6. The power output The gear 6 meshes with the first driven gear 8 and the second driven gear 7 arranged on its both sides, the first driven gear...

Abstract

The invention discloses an intelligent flexible-type soft-rod oil pumping machine which comprises a motor, a transmission device and driven wheels. The transmission device comprises a power gear, a first driven gear, a second driven gear, a driving shaft, a first driven shaft and a second driven shaft, wherein the driving shaft, the first driven shaft and the second driven shaft are arranged in parallel; the driven wheels comprise the first driven wheel and the second driven wheel. The intelligent flexible-type soft-rod oil pumping machine has the following specific advantages that the problem of eccentric wear of an oil pumping rod on an oil pipe is solved; the pumping control problem of the oil pumping machine is effectively and reasonably solved, and meanwhile the service life of oil-well oil extraction equipment is prolonged; an oil pumping machine moving device is installed for convenient oil well maintenance and can automatically retreat for 500-1000 m to arrive at an oil well maintenance station; reports do not need to be manually transferred.

Description

technical field [0001] The present invention relates to the field of petroleum exploitation machinery, specifically an intelligent flexible sucker rod that uses flexible software (soft rod) to replace the traditional sucker rod, and can intelligently adjust the length (5-15 meters) and stroke interval times of the pumping unit. (soft rod) pumping unit. Background technique [0002] The pumping units used in oil field production include beam pumping units and hydraulic shaft pumping units. Traditional pumping units are widely used in various oil fields at home and abroad due to their mature technology and reliable performance. However, various traditional pumping units It is a common phenomenon that the full load (controlled pumping) cannot be reached during oil production, which increases the consumption per ton of liquid, and the cost of oil production cannot be effectively controlled. Contents of the invention [0003] Purpose of the invention: [0004] The invention p...
