Description

Adjustable out-of-phase crank balanced oil extractor and related method
The present invention relates to the can regulate non-synchronous crank balance formula pumping unit that a kind of petroleum recovering is used.
The most popular oil well pump of petroleum industry is the sucker rod pump, and most popular pumping unit is a beam pumping unit, and non-synchronous crank balance formula pumping unit is a kind of advanced person's a beam pumping unit.
Existing non-synchronous crank balance formula pumping unit mainly comprises lifting rope system, horse head, walking beam, retarder, crank, base, balancer weight, support and central axis bearing, and the push and pull system of being made up of crossbeam bearing support, crossbeam, connecting rod and crank pin.The motor of pumping unit will move by drive belt and transmission of power is given retarder, crank on the reducer output shaft is transformed into the swing of walking beam around the central axis bearing together with push and pull system with rotatablely moving of crank, horse head is transformed into the swing of walking beam the linear reciprocating motion of lifting rope system, the lifting rope system is connected with the well rod pump, thereby crude oil in the oil well is pumped into ground.
Existing non-synchronous crank balance formula pumping unit has two important structure characteristics with respect to conventional crank-balanced pumping unit: the one, the quadratic crank mechanism that is disposed crank when horse head is in upper dead center and lower dead point position, exist in service cycle an angle theta ', θ ' is referred to as crank angle between extreme positions; The 2nd, the line of the axis hole center that crank pin is connected with crank and the axis of rotation of crank has a phase angle τ with respect to the vertical center line of crank, and τ is referred to as offset angle of crank.Because non-synchronous crank balance formula pumping unit has above-mentioned two structure characteristics, thereby under certain hole condition and operating mode of certain oil well of its adaptation, improve the kinetic characteristic and the dynamic property of quadratic crank mechanism transmission to a certain extent, reduced the torque peak Tn Max of reducer output shaft and the meritorious power consumption Nd of motor.
The shortcoming of existing non-synchronous crank balance formula pumping unit is, pumping unit for a kind of type, its polarincludedangle ' and offset angle of crank τ all be changeless, and oil well that a kind of pumping unit of type will adapt to and hole condition thereof and operating mode are complicated and changeable, its result must be the θ ' and the τ value of one group of regular collocation, may not carry out rational Match with any hole condition and the operating mode of any oil well.So, existing non-synchronous crank balance formula pumping unit can not can both make the kinetic characteristic of quadratic crank mechanism transmission and dynamic property obtain the most reasonable improvement under any hole condition of any oil well and operating mode, can both make the torque peak Tn Max of reducer output shaft and the meritorious power consumption Nd of motor obtain the most reasonable decline, meritorious power consumption Nd is obviously increased.The test data of the non-synchronous crank balance formula pumping unit that Jiang-Han Area drilling-production equipment research institute provides
