Abstract
The utility model relates to an automatic chemical feeding device for a pressured sleeve. The automatic chemical feeding device comprises an emptying valve, a chemical feeding box, a chemical feeding hole, a chemical quantity control hole, a valve and a chemical discharging pipe, wherein the emptying valve and the chemical feeding hole are arranged at the upper part of the chemical feeding box, the chemical discharging pipe is arranged at the lower part of the chemical feeding box, the tail part of the chemical discharging pipe is connected with the valve, the chemical quantity control hole is connected behind the valve, and the chemical quantity control hole is connected with the valve at one side of a sleeve. A pressure equalizing pipe is arranged in the chemical feeding box, the upper port of the pressure equalizing pipe is arranged above the medicament liquid level, and the lower port of the pressure equalizing pipe stretches outside the chemical feeding box and is connected with the valve at the other side of the sleeve, thus pressure in the chemical feeding box is the same with the pressure of the sleeve; the chemical quantity control hole is connected with the valve at one side of the sleeve, thus pressure in the chemical quantity control hole is the same with the pressure of the sleeve, self weight of chemical in the chemical feeding box can cause the chemical to automatically flow into a well with the pressure of the sleeve, the chemical can be continuously added into the sleeve, and normal production of a heavy oil well and a paraffin precipitation well can be maintained, thus the automatic chemical feeding device provided by the utility model has obvious economic benefit.
Description
Technical field
The utility model is the ground installation that the oil-field thick-oil well paraffin-troubled well is used, and is a kind of band gland pipe automatic medicine adding apparatus.
Background technology
Pumpingh well oil is thick, during wax deposition, need add thinner or paraffin remover from sleeve pipe on ground, when in the sleeve pipe pressure being arranged; Just can pour in the sleeve pipe after need medicament being pressurizeed with force (forcing) pump, ground installation is complicated, and the input expense is high; And be installed in the field; The bad management of equipment, stolen easily, be difficult to normal operation.Therefore, adopt the force (forcing) pump dosing regularly in sleeve pipe, to add medicament at present, after adding equipment is moved.This dosing method, workload is big on the one hand, and labour intensity is big, and cost of production is high, and in the bad on the other hand grasp dosing cycle, dosing is discontinuous, can not guarantee the oil well ordinary production, can produce economic loss.
Summary of the invention
The purpose of the utility model is a kind of band gland pipe automatic medicine adding apparatus of design, makes it can the aboveground Automatic Dosing of casing pressure arranged, and guarantees the long-term ordinary production of oil well.
The purpose of the utility model is achieved in that and comprises atmospheric valve, dosing tank, dosing mouth, dose control mouth, valve, drug discharging tube; Atmospheric valve, dosing mouth are installed in dosing tank top; Drug discharging tube is installed in the dosing tank bottom, and the drug discharging tube afterbody connects valve, connects dose control mouth behind the valve; Dose control mouth is connected with sleeve pipe one side valve door; Setting pressure balance pipe in the dosing tank, the pressure-equalizing pipe port is on the medicament liquid level, and the pressure balance infratubal port stretches out outside the dosing tank and is connected with sleeve pipe opposite side valve.
Dosing tank top setting pressure table.
Content gauge is installed in the dosing tank side.
The beneficial effect of the utility model is: setting pressure balance pipe in the dosing tank; The pressure-equalizing pipe port is on the medicament liquid level; The pressure balance infratubal port stretches out outside the dosing tank and is connected with sleeve pipe opposite side valve; Make its dosing tank internal pressure identical, again because dose control mouthful is connected with sleeve pipe one side valve door, so dose is controlled mouth pressure and casing pressure mutually with casing pressure
With; The deadweight of medicine can make medicament flow into automatically in the dosing tank has in the well of casing pressure; Do not need pressurized equipment just can in the well that casing pressure is arranged, add medicine, and can dosing in sleeve pipe continuously, make viscous crude, paraffin-troubled well keep ordinary production; Therefore, the utlity model has remarkable economic efficiency.
Description of drawings
Fig. 1 is the utility model embodiment sketch map.
The specific embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described.
Can be known that by figure the embodiment of the utility model comprises atmospheric valve 1, pressure meter 2, dosing tank 3, dosing mouth 4, pressure-equalizing pipe 5, content gauge 6, dose control mouth 7, valve 8, drug discharging tube 9, atmospheric valve 1, dosing mouth 4 are installed in dosing tank 3 tops; Dosing tank 3 bottoms installation drug discharging tube 9, drug discharging tube 9 afterbodys connect valve 8, and valve 8 backs connect doses control mouth 7; Dose control mouthfuls 7 is connected with sleeve pipe one side valve door, and it is a throttling arrangement that dose is controlled mouth 7 actual, according to different wells the different doses that adds is set; So that control adds dose; Prevent that the medicine in the dosing tank runs off fast, setting pressure balance pipe 5 in the dosing tank 3, pressure-equalizing pipe 5 port are on the medicament liquid level; Pressure-equalizing pipe 5 lower port are stretched out outside the dosing tank 3 and are connected with sleeve pipe opposite side valve, can the air pressure in the sleeve pipe be introduced in the dosing tank 3.Dosing tank 3 top setting pressure tables 2 are so that observe the pressure in the dosing tank 3.Content gauge 6 is installed in dosing tank 3 sides, so that observe the capacity of medicine in the dosing tank 3.
