Abstract
The utility model provides a take out oil well wellhead charge device of oil field oil recovery usefulness, irritate including storing up the medicine, the balanced valve, advance the medicine mouth, put the medicine control valve, put the pencil, the sleeve pipe valve, the single current valve, the production tree, the one side the production tree is installed to the sleeve pipe valve, the sleeve pipe valve communicates with each other with the interior sleeve pipe of well, install and irritate putting pencil one end and store up the inside that the medicine irritated and communicating with each other of lower part storing up the medicine, the other end is connected on the sleeve pipe valve, the medicine control valve is put in the installation on putting the pencil, the single current valve, the single current valve is in sleeve pipe valve end, the storage medicine is irritated and is installed the balanced valve, advance the medicine mouth, the utility model is used for when oil pumping well casing adds the medicine, need not use the pump truck, not increase equipment cost, only need an operation workman, easy operation, degree of automation is high, low in labor strength, the drug combination is even, wax removal, viscosity reduction, anticorrosive, cleaning effect good, can not lead to the fact the medicament extravagant.
Description
Technical field
This utility model is the plant equipment of a kind of oil extraction in oil field, is a kind of pumping well head chemicals dosing plant.
Background technology
Some oil well paraffinication, oil thick, can not normally produce, some oil wells contain Korrosionsmedium and oil well production instrument are produced corrosion, the oil well fouling also having is serious, cause dirt card, dirt stifled, for the impact eliminating wax deposition, oil is thick, corrosion and scaling is on oil well production, need to add the various medicaments such as paraffin remover, thinner, corrosion inhibiter, scale remover to sleeve pipe, the medicament added is after the annular space of sleeve pipe and oil pipe, return out in oil pipe bottom oil pipe again, this cyclic process reaches the purpose of wax removal, viscosity reduction, anticorrosion, scale removal.At present, oil well casing dosing has two kinds of methods: a kind of method being human at periodic intervals and irrigating in sleeve pipe, this method labor intensity is big, operator is many, and automaticity is low, and dosing is uneven, medicament is caused to waste, the bad grasp dosing cycle so that it is wax removal, viscosity reduction, anticorrosion, scale removal weak effect, and be not suitable for having on the producing well of pressure at sleeve pipe using；Another kind of method is periodically to squeeze in sleeve pipe by medicament with vehicular pump truck, and this method needs, with pump truck, to increase cost of equipment, equally exist dosing uneven, and wax removal, viscosity reduction, antiseptic effect are poor, do not reach the purpose of preferable wax removal, viscosity reduction, anticorrosion, scale removal.
Summary of the invention
The purpose of this utility model is a kind of pumping well head chemicals dosing plant of design so that it is the problem overcoming above-mentioned existence, improves wax removal, viscosity reduction, anticorrosion, scale removal effect.
The purpose of this utility model is achieved in that and includes drug storage filling, balanced valve, feeding opening, puts medicine control valve, puts pencil, sleeve valve, ball-and-seat, production tree, sleeve valve is arranged on the side of production tree, sleeve valve communicates with well inner sleeve, it is arranged on drug storage to fill the inside that pencil one end fills with drug storage of putting of bottom and communicate, the other end is connected on sleeve valve, medicine control valve, ball-and-seat is put putting to install on pencil, ball-and-seat is in sleeve valve end, and drug storage fills and installs balanced valve, feeding opening.
Booster pump is installed in the bottom that drug storage fills, and is putting installation threeway on pencil, and threeway is in puts between medicine control valve and ball-and-seat, and the entrance point of booster pump fills with drug storage and communicates, and the port of export of booster pump is connected in threeway, installs delivery valve between threeway and booster pump.
Drug storage fills outer installation and adds pump, adds delivery side of pump and is inserted in feeding opening.
The beneficial effects of the utility model are: this utility model is when oil-pumping well sheath dosing, need not with pump truck, do not increase cost of equipment, having only to an operator, simple to operate, automaticity is high, labor intensity is low, medicament mix homogeneously, wax removal, viscosity reduction, anticorrosion, features high scale-removing effect, do not result in medicament waste.
Accompanying drawing explanation
Accompanying drawing 1 is the installation diagram of this utility model embodiment.
Detailed description of the invention
1 embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings.
As seen from the figure, embodiment of the present utility model includes that drug storage fills 1, balanced valve 2, feeding opening 3, puts medicine control valve 4, puts pencil 5, sleeve valve 6, ball-and-seat 7, booster pump 10, production tree 12, sleeve valve 6 is arranged on the side of production tree 12, sleeve valve 6 communicates with well inner sleeve, it is arranged on drug storage to fill put pencil 5 one end and the drug storage of 1 bottom and fill the inside of 1 and communicate, the other end is connected on sleeve valve 6, putting medicine control valve 4, ball-and-seat 7 putting to install on pencil 5, drug storage fills installs balanced valve 2, feeding opening 3 on 1.Opening sleeve valve 6, in well head at the bottom of the liquid level in oil well casing, open and put medicine control valve 4, drug storage fills the medicinal liquid of preparation in 1 and flows automatically in sleeve pipe through sleeve valve 6, through down-hole and well liquid mixing wax removal, viscosity reduction, anticorrosion, scale removal.Chemical feeding quantity is regulated by putting medicine control valve 4, it is to avoid cause waste in medicament excess access wall.
Further measure of the present utility model is, drug storage fills the bottom of 1 and installs booster pump 10, putting installation threeway 8 on pencil 5, threeway 8 is in puts between medicine control valve 4 and ball-and-seat 7, the entrance point of booster pump 10 fills 1 with drug storage and communicates, the port of export of booster pump 10 is connected in threeway 8, installs delivery valve 9 between threeway 8 and booster pump 10.When oil well casing pressure is higher than well head, drug storage fills the medicinal liquid of preparation in 1 and can not flow automatically in sleeve pipe, now closes and puts medicine control valve 4, opens delivery valve 9, start booster pump 10 and just can irrigate medicament in sleeve pipe.Therefore, this utility model has on the producing well of pressure at sleeve pipe and could be used that.
Drug storage fills 1 outer installation and adds pump 11, and the outfan adding pump 11 is inserted in feeding opening 3, can add medicament with pump, be not required to manpower and add, reduce labor strength in drug storage fills 1.
