Abstract
The utility model discloses a casing pressure balanced well mouth closed quantitative continuous dosing device, belonging to equipment used in the oil field. The casing pressure balanced well mouth closed quantitative continuous dosing device is composed of a medicine storage box, a hydraulic pressure combination valve and a constant current controller. The bottom of the medicine storage box is connected to the hydraulic pressure combination valve by an outlet valve, a check valve and a filter pipeline, and the outlet of the hydraulic pressure combination valve is connected with a well mouth through the constant current controller pipeline. The hydraulic pressure combination valve is formed by connecting two same combined valve bodies in series or in parallel. In the casing pressure balanced well mouth closed quantitative continuous dosing device, the structure is designed reasonably, and the closed quantitative continuous dosing of the oil well can be realized; the dosing quantity can be regulated in real time, the operations of the oil well cannot be influenced; the device is safe and theft-proof, and is convenient to repair and maintain.
Description
Technical field
The utility model belongs to the oil field and uses equipment, particularly relates to a kind of cover equilibrium well head closed quantitative device for continuously adding medicine into.
Background technology
In the oil gas well mining process,, need to add different medicaments, make the maximization that exploitation is more reasonable, guarantee production efficiency because of the ground condition is different.The medicament of oil gas field use at present has two kinds of forms, and a kind of is solid-state pharmacy, during use, directly throws in the well, lets it oneself dissolve, and this mode of lottery makes the medicament rate of dissolution inhomogeneous, causes the medicament drug effect unbalanced; Another kind is a liquid pharmaceutical, during use, directly pours in the well, causes medicament just to add the big formation waste of fashionable drug effect, and the later stage efficacy of a drug is not enough, does not have the effect of application at all.And above-mentioned dual mode all is after at regular intervals, to drop into medicament again, can not realize continuous dosing, causes the serious waste of medicament, and waste of manpower.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, and a kind of cover equilibrium well head closed quantitative device for continuously adding medicine into is provided.
The cover equilibrium well head closed quantitative device for continuously adding medicine into of the utility model is to be made up of explosive box, hydraulic combined valve and constant-current controller.The bottom of explosive box is connected to the hydraulic combined valve through outlet valve, flap valve and strainer pipeline, and the outlet of hydraulic combined valve connects well head through the constant-current controller pipeline.
As the further improvement of the utility model, the hydraulic combined valve is being in series or in parallel to form of two like combinations valve bodies.
As the further improvement of the utility model, the export pipeline of the secondary valve body of hydraulic combined valve has connected dirt colleceting bucket.
As the further improvement of the utility model, the two ends of hydraulic combined valve all are connected with the two ends of high-pressure buffering pot.
As the further improvement of the utility model, the bottom pipeline of high-pressure buffering pot is connected with well head through quick dosing valve.
As the further improvement of the utility model, well head is connected with the one-level valve body of hydraulic combined valve through the casing pressure equalizing valve.
The cover equilibrium well head closed quantitative device for continuously adding medicine into of the utility model; The cover atmospheric pressure is as equilibrium pressure; Get into high-pressure buffering pot top through cover gas pressure balance pipe; Soup entering outlet valve, constant-current controller under the self gravitation effect in the surge tank, the process chemical feed pipe is the access to plant main at the uniform velocity.Cover gas pressure balance pipe and chemical feed pipe converge at main.The main caliber avoids gas-liquid to interfere with each other greater than the dosing caliber.The dosing flow process can guarantee heavy dose of dosing requirement fast.
Hydraulic combined valve and constant-current controller are the device key control unit; Device replenishes and the constant current dosing cycle through hydraulic combined valve control high-pressure buffering pot medicament; Compare with conventional sleeve equilibrium device, no high pressure medicine storing pot, medicament do not have switching flow when replenishing; Avoid personal injury, security reliability is high.No pressure vessel recondition expense, operation and maintenance cost reduces significantly.
The cover equilibrium well head closed quantitative device for continuously adding medicine into of the utility model, reasonable in design realizes sealed oil well, quantitative (constant current), continuous dosing; Can adjust in real time and add dose; Do not influence the oil well operations; Safety, antitheft, maintenance maintenance are conveniently.
Description of drawings
Fig. 1 is the structural representation of the utility model cover equilibrium well head closed quantitative device for continuously adding medicine into.
The specific embodiment
The cover equilibrium well head closed quantitative device for continuously adding medicine into of the utility model; Be to constitute by explosive box 1, hydraulic combined valve 2 and constant-current controller 3; The bottom that it is characterized in that explosive box 1 is connected to hydraulic combined valve 2 through outlet valve 4, flap valve 5 and strainer 6 pipelines, and the outlet of hydraulic combined valve 2 connects well head through constant-current controller 3 pipelines.The constant-current controller that relates in this programme is a prior art, sees that the patent No. is 201020173313.4 patent documentation.
Hydraulic combined valve 2 is being in series or in parallel to form of two like combinations valve bodies.
The export pipeline of the secondary valve body of hydraulic combined valve 2 has connected dirt colleceting bucket 9.Dirt colleceting bucket will overlap the entrained greasy dirt of gas to be collected, and when avoiding polluting soup, effectively prevents valve, the stifled phenomenon of pipeline knot.
The two ends of hydraulic combined valve 2 all are connected with the two ends of high-pressure buffering pot 7.
The bottom pipeline of high-pressure buffering pot 7 is connected with well head through quick dosing valve 8.The dosing flow process can satisfy heavy dose of dosing demand fast.
Well head is connected with the one-level valve body of hydraulic combined valve 2 through casing pressure equalizing valve 10.
