Description
Technical field
The present invention relates to the equipment of oil-field flooding, is a kind of singe screw boosting water injection pump.
Background technology
Indivedual water injection well needs water under high pressure just can be injected in stratum, each oil field all have employed multiple supercharging equipment, mainly contain ground plunger displacement pump, centrifugal pump, needing in the water injection well of high pressure with these pumps by injecting after the pressure supercharging on existing injection pipe network, all there is the high problem of fault rate in these supercharging equipments.As large in pressure fluctuation during the plunger displacement pump supercharging of ground, run not steady, bad seals is fast, management work difficulty, and maintenance is frequent, labor strength is large, pressurized water injection often pauses, and causes pressure oscillation in water injection well, to cause in well the flexible and stratum of instrument to tell sand, shorten water injection cycle, adopt ground plunger displacement pump pressurized water injection also will take position, well site; Because the injection rate of single well pressure boost water filling is few, pressure is high, just have as adopted centrifugal pump pressurized water injection that efficiency is low, consume energy large problem, and centrifugal pump is High Rotation Speed, high to the requirement of sealing when entering pump pressure and being high, existing sealing device can not meet the requirement being pressurized to hypotonic water injection well with injection pipe network.And for example Chinese patent 201010114436.5 " boosting water injector ", need ground oil pumper pressurized water injection, ground installation is huge, and cost is high, and efficiency is low.
Summary of the invention
The object of the invention is to design a kind of singe screw boosting water injection pump, overcome above-mentioned Problems existing, increase water injection rate, reduce management difficulty, extend water injection cycle.
The object of the present invention is achieved like this: comprise rotary power unit, mechanically-sealing apparatus, threeway, inlet valve, hanger, four-way, sleeve valve, single-screw (single screw) pump, sleeve pipe, the bottom of four-way is connected with the top of sleeve pipe, hanger is located on the top stomidium of four-way, the contact position of hanger and four-way keeps sealing state, the stator of single-screw (single screw) pump is connected under hanger, the stator of single-screw (single screw) pump is in sleeve pipe, mounting sleeve valve on the side mouth of four-way, threeway is installed in the upper surface of four-way, the side mouth of threeway is installed into penstock, in the top of threeway, mechanically-sealing apparatus is installed, rotary power unit is installed in the upper end of threeway, the central axis of rotary power unit is connected with the rotor of single-screw (single screw) pump through mechanically-sealing apparatus, the central axis of rotary power unit can drive the rotor of single-screw (single screw) pump to rotate.
The invention has the beneficial effects as follows: singe screw boosting water injection pump operates steadily, pulse free, failure rate is low, sealing is reliable, water injection rate can be increased, long service life, can extend water injection cycle, and the present invention is arranged on to be needed in the well of pressurized water injection, do not take ground space, therefore, the present invention can reach purpose of design, has significantly through note benefit.
Accompanying drawing explanation
Fig. 1 is assembling drawing of the present invention.
Detailed description of the invention
