Abstract
The utility model discloses a universal sleeve device with continuous adding of agents achievable. The universal sleeve device with continuous adding of the agents achievable can adjust inflowing speed of the agents and achieve continuous adding of the agents with pressure. The universal sleeve device with continuous adding of the agents achievable comprises a tank body, wherein an agent adding valve is arranged on the top of the tank body, a liquid outlet tube is arranged at the bottom of the tank body, the liquid outlet tube is provided with an adjusting valve, the liquid outlet tube is connected with a sleeve valve, and a balance tube is arranged between the tank body and the sleeve valve.
Description
Technical field
The utility model relates to a kind of thickened oil recovery Universal casing device for continuously adding medicine.
Background technology
At present a lot of oil recovery ore deposits enter " three height " development phase through for many years exploitation, and along with the acceleration of successively decreasing in the oil field, heavy oil development has been the important component part of crude oil production, and according to statistics, heavy oil wells output has reached 23.4% of my Dormant oils well production at present.In recent years, the cold excavating technologies of sleeve pipe dosing viscosity reduction that adopt were produced more in thickened oil recovery, and the sleeve pipe dosing need to bleed off casing pressure, once poured into the mode of one to two barrel of medicament by sleeve pipe, the one, put casing pressure after, cause the variation of oil well production pressure reduction, affect the oil well well of normally producing even lie; The 2nd, the disposable medicament of pouring into, action time is short, and oil increasing effect is poor, and causes the waste of medicament.
The mode of operation that on-the-spot heavy oil wells is added thinner is: at first open sleeve gate, after casing gas emptying, then add in the sleeve pipe thinner is disposable.The main cause that exists: the one, can not be according to the condition of production dynamic adjustments thinner of oil well, medicament is difficult to play a role lastingly; The 2nd, directly to the airborne release natural gas, wasted natural gas, simultaneously serious contaminated environment causes the fluctuation of oil well production pressure reduction simultaneously, affects the normal production of oil well.
Summary of the invention
The purpose of this utility model provides a kind of Universal casing device for continuously adding medicine exactly for addressing the above problem, and it can adjust the medicament inflow velocity, realizes continuous dosing with pressure.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Universal casing device for continuously adding medicine, it comprises tank body, is provided with the dosing valve at the tank body top, is provided with drain pipe in tank base, and drain pipe is provided with control valve, and drain pipe is connected with sleeve valve; Be provided with balance pipe between described tank body and the sleeve valve.
Described tank body top also is provided with the emptying valve.
Described drain pipe also is provided with inspecting valve.
The utility model adopts the mode that adds medicine storing pot according to the linker pressure balance principle, and with balance pipe balance tank body and cover overpressure, medicament relies on gravity to flow into the shaft bottom in the tank; Install simultaneously control valve additional and adjust the medicament inflow velocity, realize continuous dosing with pressure.
The beneficial effects of the utility model are:
1) can add thinner without emptying.
2) capable of dynamic is adjusted addition, improves the service efficiency of thinner, reduces labor strength.
3) reduce heavy oil wells pit shaft viscosity of thickened oil, the assurance oil well is normally produced, and improves oil well productivity.
4) contaminated environment is avoided in the discharging of minimizing natural gas.
