Abstract
The utility model relates to an auxiliary device for oil recovery, in particular to a casing medicament adding device. The casing medicament adding device comprises a medicament adding barrel, an emptying valve is mounted at the upper part of the medicament adding barrel through a pipeline, a medicament adding pipe is further arranged at the upper part of the medicament adding barrel, a medicament adding valve is mounted on the medicament adding pipe, a medicament injection pipe is arranged at the bottom of the medicament adding barrel, a medicament injection valve and a casing valve are mounted on the medicament injection pipe, the casing valve is arranged at the outer end of the medicament injection pipe, one end of a balance pipe is communicated onto the medicament injection pipe between the medicament injection valve and the casing valve, and the other end of the balance pipe is communicated to the upper part of the medicament adding barrel. The casing medicament adding device adopting the technical scheme is in a sealed state when adding a medicament and can prevent the medicament from being blown out of the medicament adding barrel when casing gas pressure is high, thereby reducing the loss of the medicament and the environmental pollution.
Description
Technical field
The utility model relates to a kind of oil recovery auxiliary equipment, particularly relates to a kind of sleeve pipe chemicals dosing plant.
Background technology
In the oilfield exploitation later stage or when running into thickened oil recovery, most wells is because viscosity of crude height, mobile difference need artificial viscosity reduction.One of artificial topmost mode of viscosity reduction is an electrical heating viscosity reduction method, because electrical heating viscosity reduction method power consumption height, cost height, uses extensivelyless in actual production, and the dosing viscosity reduction that relative cost is lower is widely used.But the dosing viscosity reduction adopts the sleeve pipe dosing more at present, and in the dosing process, because the existence of sleeve pipe gas is arranged, the medicine majority of adding is gone out by pneumatic jack, causes the cost waste, and the medicament of outflow has also caused large-scale pollution to the well site.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of technical scheme of sleeve pipe chemicals dosing plant is provided at the deficiencies in the prior art, this scheme can make medicament add fully in the well, reduces the medicament loss, reaches to reduce production costs and reduce the purpose of medicament to the pollution of environment.
The utility model is to realize like this, the sleeve pipe chemicals dosing plant, it is characterized in that, it has the explosive barrel of adding, and atmospheric valve gate open piping is installed in and adds explosive barrel top, adds explosive barrel top chemical feed pipe also is housed, the dosing valve is housed on the chemical feed pipe, adding explosive barrel bottom has medicine-pouring pipe, and the outer end that injection valve and sleeve valve, sleeve valve are contained in medicine-pouring pipe is installed on the medicine-pouring pipe, and balance pipe one end is communicated on the medicine-pouring pipe between injection valve and the sleeve valve, the other end is communicated to the top that adds explosive barrel.
The beneficial effects of the utility model are, adopt the sleeve pipe chemicals dosing plant of the technical program to be in when dosing under the close state of envelope, can prevent to overlap gas and medicament be blown out when high and add explosive barrel, reduce the medicament loss and to the pollution of environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1-adds explosive barrel, 2-emptying valve, 3-dosing valve, 4-chemical feed pipe, 5-balance pipe, 6-injection valve, 7-medicine-pouring pipe, 8-sleeve valve.
The specific embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model and principle are described further.
As shown in the figure, sleeve pipe chemicals dosing plant of the present utility model, it is characterized in that, it has the explosive barrel of adding 1, emptying valve 2 is adding explosive barrel 1 top by piping erection, add explosive barrel 1 top chemical feed pipe 4 also is housed, dosing valve 3 is housed on the chemical feed pipe 4, add explosive barrel 1 bottom medicine-pouring pipe 7 is arranged, the outer end that injection valve 6 and sleeve valve 8, sleeve valve 8 are contained in medicine-pouring pipe 7 is installed on the medicine-pouring pipe 7, and balance pipe 5 one ends are communicated on the medicine-pouring pipe 7 between injection valve 6 and the sleeve valve 8, the other end is communicated to the top that adds explosive barrel 1.
Before oil well adds chemical agent, earlier sleeve valve 8 is closed, open emptying valve 2, opening dosing valve 3 is injected into chemical agent and adds in the explosive barrel 1 by chemical feed pipe 4, close emptying valve 2 and dosing valve 3, open injection valve 6 equalizing pipes 5, open sleeve valve 8, make the sleeve pipe of the utility model and oil well form a pressure balancing system.Chemical agent relies on potential energy to continuously flow in the oil well casing by medicine-pouring pipe 7.After chemical agent uses up, shut sleeve valve 8 again, open emptying valve 2 and dosing valve 3, again medicament is added in the explosive barrel 1, dosing work is constantly gone on, reach purpose the oil well dosing.
