Abstract
An automatic continuous adding device for a foaming agent at a wellhead of a gas well is a special device for continuously adding the foaming agent into the wellhead of the oil field. Is characterized in that: the bottom of the medicine storage tank is connected with a medicine outlet pipe, and a medicine outlet control valve, a check valve and a flowmeter are sequentially fixed on the medicine outlet pipe. The other end of the flowmeter is connected with a tee joint. The clamp is connected to one end of the tee, and the balance guide pipe is connected to the other end of the tee. The balance guide pipe is welded on the wall of the medicine storage tank, and the open end of the balance guide pipe is arranged at the upper part in the medicine storage tank. The effect is as follows: the pressure in the medicine storage tank and the pressure in the annular space of the oil sleeve of the oil well form pressure balance through the balance guide pipe, the foaming agent liquid medicine is automatically and continuously dripped into the annular space of the oil sleeve by means of gravity, the operation is simple and convenient, external force is not needed, the full play of medicine properties is facilitated, the labor intensity of workers is reduced, and the production cost is saved.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of gas well mouth that is used for adds the isolated plant that is used as medicine continuously.
Background technology
Gas field development is to the middle and later periods, and the gas well strata pressure reduces, and production capacity reduces, and the gas fluid-carrying capability weakens in the well, and pit shaft hydrops phenomenon is outstanding gradually, needs to add frother to pit shaft.Add frother, reach water pumping gas production, can improve the gas fluid-carrying capability.
At present, method toward the interior filling of well frother normally manually adds or the adding of special-purpose dosing vehicle, the instantaneous heavy dose frother of annotating in oil sets annular space, its disadvantage are that frother soup utilization rate is low, property of medicine performance is insufficient, need manually-operated and special-purpose dosing vehicle.
The utility model content
The purpose of this utility model is: provide a kind of gas well mouth frother automatically continuous adding apparatus, make the oil sets annular space pressure of medicine storing pot internal pressure and oil well constitute pressure balance by balance pipe, make the frother soup rely on the automatic continuous drip of gravity in oil sets annular space, reduce labor strength, save special-purpose dosing vehicle, improve the foaming pharmacy effect, improve the gas fluid-carrying capability.
The technical solution adopted in the utility model is: the automatically continuous adding apparatus of gas well mouth frother, mainly form by dosing funnel, dosing valve, atmospheric valve, balance pipe, medicine storing pot, drug control valve, ball-and-seat, flow meter, threeway and clip.Medicine storing pot is fixed on the base.The top of medicine storing pot is fixed with union, is fixed with dosing valve on union, and dosing valve top is connected with dosing funnel 1.It is characterized in that: the bottom of medicine storing pot is connected with drug discharging tube, is fixed with drug control valve, ball-and-seat and flow meter on the drug discharging tube successively.The other end at flow meter is connected with threeway.Jointing clip on the one end pipeline of threeway is connected with balance pipe in the other end of threeway.Balance pipe is welded on the tank skin of medicine storing pot, and the openend of balance pipe is at the medicine storing pot internal upper part.Make medicine storing pot by oil sets annular space UNICOM in balance pipe and the oil well, oil sets annular space pressure and medicine storing pot internal pressure balance in the oil well.
In order to be clear that the volume residual of frother soup in the medicine storing pot, on the outer wall of medicine storing pot, be fixed with content gauge.
For the ease of operation, the pressure in the energy emptying medicine storing pot is fixed with blow-down pipe on the top of medicine storing pot, is connected with atmospheric valve on the blow-down pipe.
The gas well mouth frother is the installation and the use of adding apparatus continuously automatically: consult Fig. 1.Before the interior dosing of oil well, clip 11 is connected with the gas well sleeve gate; In grug feeding jar 5, fill it up with the frother soup by dosing funnel 1 and dosing valve 2.During dosing, earlier the gas well sleeve gate is closed, open atmospheric valve 3 releases, to medicine storing pot 5 in, adds medicament, by content gauge 12 observation dosings highly, close dosing valve 2 and atmospheric valve 3 after filling it up with the frother soup through dosing funnel 1.Slowly open drug control valve 7, ball-and-seat 8, this moment, medicine storing pot 5 constituted pressure balancing system by balance pipe 4 and oil sets annular space, utilized flow meter 9 to regulate the frother drip velocity, realized filling frother in the oil jacket annular space.Content gauge 12 guarantees that patrolling the well workman can observe the frother surplus when patrolling well simultaneously, regularly to replenish.Medicine storing pot 5 is linked up through threeway 10 and oil sets annular space by balance pipe 4, make this device and oil sets annular space constitute a pressure balancing system, frother relies on the self gravitation continuous drip in oil sets annular space, medicament in the shaft bottom with after gas mixes, hydrops density reduces, be transformed into the foam-like fluid, realize the water pumping gas production purpose.
The beneficial effects of the utility model: the automatically continuous adding apparatus of the utility model gas well mouth frother, make the oil sets annular space pressure of medicine storing pot internal pressure and oil well constitute pressure balance by balance pipe, the frother soup relies on the automatic continuous drip of gravity in oil sets annular space, easy and simple to handle, need not external force, help giving full play to and reducing labor strength of the property of medicine, saved cost of production.The utility model device both can be applicable to straight well, also can be applicable to directional well, had wide range of applications.Save special-purpose dosing vehicle, improved the effect of foaming medicament, improve the gas fluid-carrying capability.
