Abstract
A pulse type oil pumping unit includes oil pumping structure, life structure, frame structure, powder structure and control structure. Natural gas with 0.6 MPa pressure is burnt to drive oil pump via piston rods and steel cable, one regulating valve controls the operation speed at 0.25-0.4 m/s and an other regulating valve controls the falling speed of oil pumping rod at 0.3-0.5 m/s. The present invention is suitable for oil production in both high pressure and low pressure oil fields.
Description
The invention belongs to the oil producing operation facility of petroleum industry, particularly a kind of what be applicable to oil field operation is the controlling method for pulse oil pumping unit and the device thereof of the energy with the rock gas.
At present, the oil producing operation in oil field generally all uses beam pumping unit both at home and abroad, its structural principle is to realize oil pumping by motoring crankrocker mechanism and slider-rocker mechanism, motor power (output) is 37-45KW, the year power consumption reaches 21-24 ten thousand kwh, need ten thousand yuan of electricity charge 12-14, power consumption is very big, has increased the produce oil cost.In addition, once adjust stroke, jig frequency during the beam pumping unit oil producing operation, and the oil field geologic situation is changeable, can not chooses the best stroke of pumping unit, jig frequency, limit high oil production.
The objective of the invention is to overcome the deficiency of beam pumping unit technology, provide a kind of province can, energy-conservation, stroke, jig frequency is arbitrarily adjustable, the controlling method for pulse oil pumping unit and the device thereof of high oil production.
Task of the present invention is, controlling method for pulse oil pumping unit and device thereof have the oil pumping structure, promote structure, airframe structure, dynamic structure, control structure.Pulse oil pumping unit is with the pressure rock gas of gas well or supply station output, the input energy storage canister, after treating that energy storage canister pressure reaches working pressure, again the control system manually operated valve is opened, allow power gas enter cylinder, piston in the cylinder is under pressure promotes, and piston rod drives wire rope, and the pulley traction rod line carrier on support arm promotes the oil pump oil pumping.When piston rod reached the precalculated position, spacing driving lever was depressed the commutation contact, the switching gas circuit commutation.At this moment, power gas no longer enters operating valve, and the gas in the cylinder is under the effect of oil well inner member potential energy, discharge by the disappointing path of operating valve, the piston rod inverted running walks to the precalculated position, and spacing driving lever has been dialled the selector valve contact, switching gas circuit commutation, air feed, piston piston rod under pressure brings into operation again.
Design principle of the present invention, promoting oil pumping is to finish with the rock gas work done of certain pressure, the potential energy work done that member gravity such as oil well pump fall after rise is finished.Be ∑ PiShi+ ∑ mihi → W (FL) gas energy, the work done of potential energy coupling, the scientific utilization natural energy is realized energy-saving and cost-reducing.
The inventive method and device solves thereof the technical problem of recovering the oil without electric energy, thereby save the investment and the operating cost of recover petroleum.One, adopting the rock gas of low pressure 〉=0.6Mpa is the power oil pumping, and under totally-enclosed environment, the potential energy that utilizes oil pumping member gravity such as sucker rod, pump to produce makes the cylinder piston backhaul, also is that oil well pump falls after rise; Two, select the single effect cylinder of pneumatic control for use, active chamber pressure is working pressure in full force and effect, and air feed is " pulsed ", reduces working pressure 30%, energy saving more than 40%; Three, two groups of cylinder synchronous operations are by one-way throttle valve adjustment control separately; Four, use the oil pumping stroke of spacing driving lever and selector valve control pumping unit; Five, can use two-shipper polyphone oil pumping structure for the oil recovery that adapts to the highpressure area.
