Description
Technical field
A kind of well liquid of the present invention drives pressure charging system and is related to a kind of drive supercharging well liquid of liquid in artificial lift technology field
Pressure charging system is driven, supercharging well liquid is driven using the liquid and drives pressure charging system generation high voltage power liquid, pass through the power liquid pipe in pit shaft
Or the specific channels such as oil pipe are transmitted to underground reversing pumping unit group, driving oil pumping pump work.Produced liquid in oil well and weary power fluid one
It rises and ground is transported to by production fluid channel, a part of production fluid therein is cooled down, by necessary after desanding processing and conduct
Power fluid recycles, and is a kind of practical novel designs for having higher operational efficiency, adapting to special well type, can be in oil
Field artificial lift field wide popularization and application.
Background technology
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.Once hydraulic piston pump, the hydraulic jet pump being applied in oil field belong to no bar lifting, using crude oil as power fluid, driving
Set under a well generates reciprocating motion, to which produced liquid in oil well is given rise to ground.According to weary power fluid whether with produced liquid in oil well
Mixing, is divided into as two kinds of open type and enclosed.For open type hydraulic piston pump, weary power fluid is transported to after being mixed with produced liquid in oil well
Ground recycles then using water-oil separating using the crude oil isolated as power fluid, due to taking for water-oil separating processing
With fairly expensive, this biggest obstacle promoted and applied as obstruction hydraulic piston pump.For enclosed hydraulic piston pump, weary power fluid
Ground is returned to by an individual runner to recycle, and avoids water-oil separating link in this way, but due to increasing one
Runner so that down-hole string complicatedization.Sewage the opening as power fluid at auto purification station occur after this again since
Formula hydraulic piston pump can also avoid water-oil separating link, but bringing influences produced liquid in oil well metering and reversing slide valve knot
Structure is not suitable with the new problem of sewage power fluid, constrains the use of this hydraulic piston pump.Beijing Di Weier petroleum gas skills
The patent of invention of art development corporation, Ltd.（Application number 200410074730.2）Propose a kind of nothing using clear water as power fluid
Bar hydraulic oil pumping system, weary power fluid are not mixed with produced liquid in oil well, but are returned from former pipeline.One existing for this technology
Problem is：Power fluid leakage is serious, needs that fresh water pipeline is transported or be laid with tractor, cost is made to increase.
In view of above-mentioned technology there are the problem of, oil-extracting well production fluid of the present invention carry out it is necessary cool down, desanding processing
It is used afterwards as power fluid, simplifies water-oil separating link, avoid the fluid infusion problem of clear water power fluid.
Invention content
The purpose of the invention is to overcome the weary power fluid of hydraulic pump system and produced liquid in oil well blending transportation to ground
Face could provide a kind of well liquid drive pressure charging system, only carry out gas-liquid-solid by water-oil separating as the deficiency that power fluid uses
Separation；Overcome sewage power fluid open type hydraulic pump system, weary power fluid and produced liquid in oil well mixed influence oil well output meter
The deficiency of amount；Overcome the complicated deficiency of enclosed hydraulic pump system down-hole string；Overcome Rodless hydraulic oil pumping system dynamic
Power liquid-tight formula recycles, and needs the deficiency of frequent fluid infusion.Well liquid provided by the invention drives supercharging device and uses oil well output
Liquid is cooled down, is recycled as power fluid after desanding processing by necessary, and power fluid separating treatment expense or fluid infusion expense are saved
With.
The present invention the technical solution to solve the technical problem is that：
A kind of well liquid drive pressure charging system include liquid case, high-pressure three-plunger pump, primary separator, second-stage separator, high pressure line,
Valve group, casing connection pipeline and oil pipe connecting pipeline.
Can a kind of well liquid be driven pressure charging system to be mounted in a skid, outer mask is with theft-proof room, convenient for antitheft, heat preservation
It is moved with scene.
It includes separator, booster pump, valve group, filter, liquid case, external water that a kind of well liquid of the present invention, which drives pressure charging system,
Source spare interface, heating device, cooling device, control system, skid room etc..The liquid being pressurized is needed to can come from stratum,
It can come from external mobile or fixed water source.Liquid from stratum is needed due to formation sand production and with natural gas by dividing
From device by liquid sand grains and natural gas detached, the sand grains after separation by separator lower part sand removing hole be discharged, naturally
Gas then enters petroleum pipeline by the outlet on separator top.To ensure separating effect, the present apparatus using two separators into
Row two-stage detaches.The liquid after two-stage cools down desanding is directed to supercharging by filter device in the middle part of from second level separator
Pump intake drives extracting device of oil by power fluid pipelined after pressurization to underground liquid.Valve group is made of 4 shut-off valves, passes through 4
The break-make of shut-off valve combines, and can carry out pulling operation and oil well cleanup operation of underground liquid driving device etc..It is cold in winter
Area can install heating device additional to prevent liquid from freezing and control system normal operation, can also be thick by being realized to liquid heating
Oil reservoir heat tracing is exploited；When in skid room when the temperature is excessively high, cooling device can be installed additional, with Guarantee control system normal work, liquid
Temperature will not be excessively high.
The advantageous effect that a kind of well liquid of the present invention drives pressure charging system is：Using produced liquid in oil well adequately cool down and remove
Sand, then become power fluid through high-pressure three-plunger pump pressurization, commutation unit, power fluid are driven by power fluid pipelined to underground liquid
Ground is reached after being mixed with stratum production fluid after acting, a part of liquid therein makes as power fluid cycle again after separation
With, it is such to recycle, the metering of produced liquid in oil well is not influenced.It, can be by the break-make combination for 4 shut-off valves that supercharging device is arranged
The pulling operation of row Set under a well or the clean-out service of oil well.Oil-extracting well production fluid of the present invention carry out it is necessary cool down, desanding
It is used as power fluid after processing, simplifies water-oil separating link, avoid the fluid infusion problem of clear water power fluid.
A kind of well liquid of the present invention drives pressure charging system and is mounted on skid pedestal, can be placed in oil well or well group as needed
Around, it is easily installed, moves, it is easy to use.
