It is a kind of that the purpose of this utility model is to provide, the difference of utilizing the required water injection pressure of dried net pressure of water filling and water filling individual well is as power, when reducing high pressure water injection, suck the part water at atmospheric pressure again, reduce the consumption of high pressure water injection amount, reasonable buck configuration is with this high oil field water injection comprehensive utilization device that reduces production costs.
The utility model is achieved in that by high pressure water injection pipe 1, water under high pressure by-pass valve control 2, dirt separator 3, water under high pressure pressure meter 4, overbottom pressure water aspirator 5, low pressure water injection pipe 6, water supply control valve 7, flow meter 8, water pressure gauge 9 is synthesized in step-down, water filling (or water mixing) well control system valve 10, water filling (or water mixing) well 11 is formed, high pressure water injection pipe 1 is communicated with dirt separator 3 through water under high pressure by-pass valve control 2, and be communicated with overbottom pressure water aspirator 5, between dirt separator 3 and the overbottom pressure water aspirator 5 water under high pressure pressure meter 4 is arranged, low pressure water injection pipe 6 is through water supply control valve 7, flow meter 8 is communicated with overbottom pressure water aspirator 5, and overbottom pressure water aspirator 5 is communicated with water filling (or water mixing) well 11 through water injection well valve 10.
The utility model also adopts following technical scheme:
High pressure water injection by-pass valve control 2 is housed on high pressure water injection pipe 1, on dirt separator 3 tops cock 12 is housed, sewage draining valve 13 is equipped with in the bottom.
Dirt separator 3 outputs are communicated with overbottom pressure water aspirator 5 inputs.
Flow meter 8 is communicated with another input of overbottom pressure water aspirator 5.
The synthetic output C of the step-down of overbottom pressure water aspirator 5 is communicated with water filling (or water mixing) well 11 through water injection well valve 1O.
Be communicated with the synthetic water pressure gauge 9 of step-down is housed on the water pipe.
Overbottom pressure water aspirator 5 is respectively high-voltage output end mouth A, low pressure water supply output port B by three ports, step-down synthetic water output port C.
Hydraulic spray 14, suction chamber 15, mixing chamber 16 are arranged on the overbottom pressure water aspirator 5, and hydraulic spray 14 communicates with suction chamber 15, and suction chamber 15 is adjacent with mixing chamber 16.
Advantage of the present utility model is: the difference of utilizing the required water injection pressure of dried net pressure of water filling and water filling individual well is as power, when reducing high pressure water injection, suck the part water at atmospheric pressure again, reduce the consumption of high pressure water injection amount, rationally buck configuration reduces production costs with this, suck the low pressure output, save high pressure water injection, alleviate the load of high-pressure hydraulic pump, saves energy.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of overbottom pressure water aspirator 5.
Below in conjunction with accompanying drawing the utility model is further described:
High pressure water injection pipe 1 is communicated with the input port A of overbottom pressure water aspirator 5 through high pressure water injection by-pass valve control 2, dirt separator 3.
