Description
Technical field
A kind of well liquid of the utility model drives reciprocal reciprocating oil pumping system and is related to one of artificial lift technology field liquid drive nothing
Bar oil pumping system generates high voltage power liquid especially with ground power unit, passes through power liquid pipe in pit shaft or oil pipe etc.
Specific channel is transmitted to underground reversing pumping unit group, driving oil pumping pump work.Produced liquid in oil well passes through oil together with weary power fluid
The channels such as pipe or oil jacket annulus are transported to ground, and a part of production fluid therein is made again after necessary degasification, desanding processing
For power fluid recycling, be it is a kind of with higher operational efficiency, adapt to the practical novel designs of special well type, Ke Yi
Oil field artificial lift field wide popularization and application.
Background technique
In the artificial lift technology field of oil field, existing artificial lift technology, which can be divided into, to be had bar to lift and lifts two greatly without bar
Class.
Belonged to no bar lifting, using crude oil as power fluid, driving in the hydraulic piston pump that oil field is applied before more than 20 years
Set under a well generates reciprocating motion, so that produced liquid in oil well is given rise to ground.Later due to using stratum sewage instead as power
The working environment of liquid, unit sharply deteriorates, and abrasion aggravation can not establish commutation pressure difference.According to weary power fluid whether with oil well produce
Liquid mixes out, and is divided into open type and two kinds of enclosed.For open type hydraulic piston pump, weary power fluid is defeated after mixing with produced liquid in oil well
It is sent to ground, then using water-oil separating, is recycled the crude oil isolated as power fluid.For enclosed hydraulic piston
Pump, weary power fluid return to ground by an individual runner and are recycled.Auto purification station occur after this again since
Open type hydraulic piston pump of the sewage as power fluid.Due to the down-hole string of expensive water-oil separating processing cost, and/or complexity
Structure, and/or influence produced liquid in oil well metering, and/or the problems such as reversing slide valve inadaptability in structure sewage power fluid, at present waterpower
Piston pump has dropped out use.
The patent of invention (application number 200410074730.2) of Beijing Weidier Petroleum Natural Gas Technology Development Co., Ltd
A kind of Rodless hydraulic oil pumping system using clear water as power fluid is proposed, weary power fluid is not mixed with produced liquid in oil well, but
It is returned from former pipeline.Power fluid not work done when power fluid returns, Set under a well carry out undershoot by the suspending weight of travelling valve lower part
Journey.There are Railway Projects for this technology: 1, the upper and lower stroke load of dynamical system is seriously uneven, and upstroke dynamical system is not only
Produced liquid in oil well is lifted, also to lift suspending weight, down stroke dynamical system not work done, dynamical system power is big, power utilization
It is low, it is also necessary to configure biggish energy storage device；2, by suspending weight downlink, the down stroke time is not adjustable；3, hole angle cannot be too
Greatly, it otherwise will be unable to by suspending weight downlink；4, reversing mechanism is placed on ground, and the commutation response time is long；5, although be
Closed system, there are still power fluids to miss problem, and the supplement of power fluid is transported or is laid with fresh water pipeline by tractor, makes cost
Increase.
