Description
Technical field
The utility model belongs to oil well technical field, particularly relates to a kind of oil well constant flow grug feeding jar.
Background technology
Pick up in process at oil extraction in oil field and oil gas collection and need in oil well oil, casing annulus, to add the chemical for oil recovery such as Wax removing agent for oil well, flow improver for crude oil, demulsifier, antisludging agent, corrosion inhibiter, thinner and bactericide to improve the mobility of crude oil or to solve the problems such as paraffin deposit, equipment corrosion and fouling.
Well wellbore corrodes and in fouling preventive action, traditional artificial well head medicine-adding is difficult to ensure adding continuously of medicament.Existing electrodynamic pump device for continuously adding medicine needs could be run by impressed current, and its equipment failure rate height needs often maintenance, poor reliability, has certain resource loss.Some are also had to drip the device of medicine easily by free gravity, its advantage be can be used for high sticky medicament dosing, do not need the external world to provide power, failure rate is low substantially not to need repairing and reliability high, but deposit the fatal defects that dosing speed reduces gradually with liquid level reduction in medicinal cupping, be difficult to the flexibility application meeting Oil Field.
Summary of the invention
The utility model provides a kind of oil well constant flow grug feeding jar, and to solve in above-mentioned background technology in traditional chemicals dosing plant, medicament adds undesirable continuously, and needing externally provides external force, is difficult to the problems such as the flexibility application meeting Oil Field.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of oil well constant flow grug feeding jar, it is characterized in that: comprise dosing valve handwheel, grug feeding jar, injection control valve, atmospheric valve, put casing gas interface, pressure gauge connection, safety valve, balance pipe, drug storage liquid level, fluid reservoir, dividing plate, constant level, tube connector A, constant-pressure tank, sleeve pipe, pressure meter, tube connector B, the upside of described grug feeding jar is provided with dosing mouth, the top of described dosing mouth is provided with dosing valve handwheel, fluid reservoir is provided with in the middle of in described grug feeding jar, the top of described fluid reservoir is provided with drug storage liquid level, described dividing plate is positioned at the below of fluid reservoir, described constant level is positioned at below dividing plate, described constant-pressure tank is positioned on the downside of constant level, described balance pipe is positioned on the left of grug feeding jar, and run through fluid reservoir and dividing plate, described tube connector A is positioned at balance pipe side, the lower end of described tube connector A connects injection control valve, described tube connector B connects injection control valve and sleeve pipe, described atmospheric valve is positioned at the below of fluid reservoir, described safety valve is positioned at atmospheric valve side, described sleeve pipe is positioned at the below of fluid reservoir, describedly put one end that casing gas interface is positioned at sleeve pipe, described pressure gauge connection is positioned at puts casing gas interface side, described pressure meter is positioned on pressure gauge connection.
Described tube connector A runs through dividing plate, constant-pressure tank, injection control valve.
Described tube connector B is identical with the diameter of tube connector A.
The beneficial effects of the utility model are:
In 1 this patent when sleeve pipe superpressure, safety valve meeting automatic deflation, the speed simultaneously by regulating main control valve to regulate injection, and then reach the effect of continuous injection.
2 this patents are by the pressure between balance liquid storage pot and constant-pressure tank, and automatic liquid supply, keep injecting medical liquid invariant position, thus it is constant to reach injection pressure, the injection valve opening in injection control valve is constant, the dosing constant airspeed made.
In 3 this patents, when the liquid level of constant-pressure tank is reduced to balance pipe lower end, namely casing gas enters the pressure that balance pipe supplements fluid reservoir, and when liquid enters into constant-pressure tank, constant level rises; When liquid level rises to the lower end of balance pipe, casing gas cannot enter balance pipe, stops to fluid reservoir air feed, and fluid reservoir also stops to constant-pressure tank industry, and this self-regulating process is that constant-pressure tank liquid level remains on balance pipe lower surface always.Reach the object of medicine outlet constant voltage injection.When injection control valve opening one timing, its flow is also invariable.
4 this patents can be used for high sticky medicament dosing, do not need the external world to provide power, failure rate is low substantially not to need repairing and reliability high, there is the practical valency in very high market.
There is not the fatal defects reduced gradually with liquid level reduction in medicinal cupping in the medicine speed of 5 this patents, is therefore easy to the flexibility application meeting Oil Field.
The structure of 6 this patents is simple, and cost is low, provides a kind of dosing speed that makes not reduce and the oil well constant flow grug feeding jar of decline with liquid level in tank, do not need to provide power by electricity, effectively can save electric energy according to pressure balance dosing principle.
