Description
Technical field
The utility model belongs to the oil field and uses medicine machine, particularly relates to the passive gas injection well well head chemicals dosing plant of adopting of a kind of high pressure.
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 is inhomogeneous because of the medicament rate of dissolution, 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, provides a kind of high pressure the passive gas injection well well head chemicals dosing plant of adopting.
The passive gas injection well well head chemicals dosing plant of adopting of the high pressure of the utility model; Be to constitute by explosive box and hydraulic combined valve; Described hydraulic combined valve is to drive storehouse, driving pressure release storehouse, a left side, left air inlet storehouse, dosing storehouse, right air inlet storehouse, right driving pressure release storehouse and the right storehouse that drives by a left side to constitute; Be respectively equipped with left air inlet storehouse and right air inlet storehouse in the both sides in dosing storehouse, left air inlet storehouse drives the pressure release storehouse with a left side respectively and is communicated with driving storehouse, a left side, and right air inlet storehouse drives the pressure release storehouse with the right side respectively and is communicated with the right storehouse that drives.The outlet of explosive box through outlet valve, flap valve and strainer be connected with the inlet in dosing storehouse, the outlet in dosing storehouse injects well head through unidirectional valve; Oil pipe high pressure outlet pipe is communicated with left air inlet storehouse and right air inlet storehouse respectively.
As the further improvement of the utility model, there are a left damping, buffering storehouse and a left side to drive the storehouse and connect, right damping, buffering storehouse connects with the right storehouse that drives.
Further improvement as the utility model is provided with flow regulator on the export pipeline of oil pipe.
Further improvement as the utility model is provided with the defrosting heating film outside the hydraulic combined valve.
As the further improvement of the utility model, there is drive unit to drive booster engine drive dc generator and connects with the defrosting heating film.
The passive gas injection well well head chemicals dosing plant of adopting of the high pressure of the utility model during work, is opened the explosive box outlet valve, and the explosive box inner liquid medicine is filled it up with hydraulic combined valve dosing storehouse.The oil pipe gases at high pressure get into the air inlet storehouse.This moment, opened in the right pressure release storehouse that drives, and gases at high pressure are released to atmosphere, and driving pressure release storehouse, a left side is closed, and left air inlet storehouse drives the storehouse with a left side and is communicated with.Gases at high pressure promote plunger body and start the setting stroke.The soup in medicament storehouse is injected into the well head annular space through the extruding of plunger body.The setting running finishes, and then left air inlet storehouse is communicated with left pressure release storehouse, and gases at high pressure directly get into atmosphere.Right air inlet storehouse is communicated with the right storehouse that drives, and gases at high pressure promote plunger body and start the return stroke.Finish to setting running.Get into next and add the pharmacy work circulation.
The passive gas injection well well head chemicals dosing plant of adopting of the high pressure of the utility model, reasonable in design, airtight dosing has guaranteed the safety of production operation; But according to hole condition and medicament characteristic real-time regulated flow, can realize the continuous and quantitative dosing, flow-control is accurate.
Description of drawings
Fig. 1 is the passive structural representation of adopting gas injection well well head chemicals dosing plant of the utility model high pressure.
The specific embodiment
