Description
One, technical field
The utility model relates to a kind of boosting water injector of giving oil field low permeability pay water filling.
Two, background technology
Shengli Oil Field is the structural oil field of fault block, has the high permeability zones piece that the hyposmosis block is also arranged in the zone of division management, accounts for leadingly as the high permeability zones piece, just press pressure injection water system in the construction of high permeability zones piece.The hyposmosis block can only be built the high pressure water injection device on individual well, satisfy the requirement of low permeability oil field high pressure water injection, and the high pressure water injection device also can be built distributing room for water injection in, is passed to the low permeability oil field individual well by the booster pump supercharging again to the defeated next press water of water flooding pump station.Give at present and exist water filling control shakiness in the low permeability oil field individual well water injection technology, the problem that water injection rate is suddenly big or suddenly small can not be carried out water filling by the waterflood project of design, does not reach the ideal effect of water filling.
Three, summary of the invention
The new purpose of this practicality provides a kind of boosting water injector, solves the problem that the injection flow shakiness that exists in the above-mentioned prior art does not reach the water filling ideal effect.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of industrial computer, pressure sensor, flow transmitter, booster pump, water tank and water distribution flow process, it is characterized in that the booster pump import links to each other with distributing room for water injection header or water tank, and outlet links to each other with the water distribution flow process by gate valve; The water distribution pipeline, the pump discharge that are provided with two parallel connections in the water distribution flow process are regulated pipeline and distributed water flow return line; Be provided with pressure sensor and flow transmitter by preface on the pipeline before water distribution pipeline; Be provided with a gate valve before and after the injection well downhole flow regulator on the distribution pipe of two parallel connections separately, front and back at injection well downhole flow regulator outlet gate valve are provided with pressure sensor and flow transmitter separately, be provided with a gate valve on the pipeline before the injection well downhole flow regulator outlet is confluxed, the export pipeline of injection well downhole flow regulator links to each other with water injection well or links to each other with water tank by the distributed water flow return duct; Pump discharge is regulated the front of circuit design at booster pump outlet gate valve, with booster pump outlet vertical connection, to fall L shaped pipeline section reeve water tank, is provided with flow control valve and gate valve by preface on this pipeline section; The holding wire of pressure sensor, flow transmitter and flow control valve links with industrial computer respectively.
Compared with the prior art the utility model has that the control injection flow is stable, flow measurement is accurate, can reach the advantage of waterflooding requirement and flood effectiveness by waterflood project.

Five, the specific embodiment
The utility model is made up of industrial computer, pressure sensor, flow transmitter, booster pump, water tank and water distribution flow process, it is characterized in that the booster pump import links to each other with distributing room for water injection header or water tank, and outlet links to each other with the water distribution flow process by gate valve; The water distribution pipeline, the pump discharge that are provided with two parallel connections in the water distribution flow process are regulated pipeline and distributed water flow return line; Be provided with pressure sensor and flow transmitter by preface on the pipeline before water distribution pipeline; Be provided with a gate valve before and after the injection well downhole flow regulator on the distribution pipe of two parallel connections separately, front and back at injection well downhole flow regulator outlet gate valve are provided with pressure sensor and flow transmitter separately, be provided with a gate valve on the pipeline before the injection well downhole flow regulator outlet is confluxed, the export pipeline of injection well downhole flow regulator links to each other with water injection well or links to each other with water tank by the distributed water flow return duct; Pump discharge is regulated the front of circuit design at booster pump outlet gate valve, with booster pump outlet vertical connection, to fall L shaped pipeline section reeve water tank, is provided with flow control valve and gate valve by preface on this pipeline section; The holding wire of pressure sensor, flow transmitter and flow control valve links with industrial computer respectively.
The utility model will be to be installed in the water filling distributing room for water injection, booster pump 9 imports 8 are connected with the distributing room for water injection header, also can be installed in well head, waterline with water be passed to water tank 7, the booster pump import is connected with water tank, booster pump is when normal water filling, booster pump goes out saliva and advances a water distribution pipeline or 2 water distribution pipelines through pressure sensor 2 and flow transmitter 3, advances a water distribution pipeline under the normal condition, and another is standby.Pressurized water advances injection well downhole flow regulator 5 through gate valve 4 and enters water injection well through pressure sensor and flow transmitter and water injection well inlet tube 6 again, normal water filling, pressure signal and the online industrial computer 1 of constantly being defeated by of flow signal before and after the injection well downhole flow regulator are handled calculating, all the time injection flow is controlled in the water injection parameter of design, if the too high water injection rate of water injection pressure is excessive, industrial computer just gives an order and opens opening degree control water injection pressure and the flow of flow control valve 10 by the controlled pressure control valve, unnecessary current recovery tank, when stopping water filling, the water of water lines is got back to water tank by the distributed water flow return line, annotate the water of not entering at ordinary times and also can get back to water tank through this pipe.
