Abstract
The utility model discloses a micro flow liquid automatic distributing device used in oil industry which is suitable for water injection stations and oil extraction stations of oil industry to inject all kinds of chemical and chemical agents to the underground as well as the locations such as the one bump against a plurality of tanks of a chemical plant, etc, that needs to automatically distribute liquid according to need. The device is provided with a controller and an electromagnetic valve, wherein, the electromagnetic valve is communicated with a liquid distributing resource and an injection inlet through pipelines and is connected with the controller through a control line. The time of the cross linking of the system can be effectually adjusted and the consistence of the cross linking agent and the time of addition of every injection well can be accurately distributed, thus perfectly meeting the needs of chemical oil-displacing of the oil field, improving the operating effect of chemical oil-displacing and reducing the production cost.
Description
Technical field
The utility model belongs to the oil production equipment of petroleum industry, micro-flow liquid automatic allocation device particularly, be applicable to the water-injection station of petroleum industry, the station of recovering the oil, inject various chemicals and chemical agent to the down-hole, also be suitable for chemical plant one pump many stills are added the place that chemical agents etc. need distribute liquid automatically on demand.
Technical background
At present,, adopt the mode of many mouthfuls of wells of a constant displacement pump supply to distribute crosslinking agent more, regulate the addition of each well by the fine adjustment valve according to the individual well flow meter at the mining site of the petroleum industry employing chemical displacement of reservoir oil.But because the individual well addition is considerably less, general injection allocation 120m
3The well of/d, design of crosslinked agent concentration are 500mg/L, and adding cross-linked dosage every day is 60kg, and flow is 1.9L/h.Owing to reasons such as the control ability of control valve and flowmeter accuracy, cause error in dipping, wellhead sampling finds that crosslinker concentration and schematic design deviation are too big.Though on operating procedure and method, carried out many-sided improvement, but still can't resolve above problem.Usually adopt a pump that many wells are added when mining site is used low pressure well interpolation crosslinking agent technology in addition, press design time control valve switch by the staff.Therefore, be badly in need of accurately distributing the device of crosslinking agent under the development small flow rate, otherwise, be difficult to realize the design object of injection allocation cross-linked polymer, have a strong impact on the mining site result of use of the cross-linked polymer displacement of reservoir oil, increased cost of production.
Summary of the invention
The purpose of this utility model be make a kind of reliable operation, can automatic accurate distribution the micro-flow liquid automatic allocation device, overcome defective of the prior art, improve the result of use of the chemical displacement of reservoir oil, reduce production costs.
The present technique solution can reach above-mentioned purpose: micro-flow liquid automatic allocation device, this device have controller and electromagnetic valve, distribute source and inlet to be communicated with electromagnetic valve and liquid by pipeline; Use control line that electromagnetic valve is connected with controller.
After using the utility model, the scene regulates and distributes the time according to crosslinking agent and reservoir condition difference by controller, just can reach the purpose of control cross-linking system crosslinking time.This device is the crosslinking time of regulation system effectively, crosslinker concentration and interpolation time that well is respectively injected in accurate distribution, satisfies the crosslinked polymer flooding mining site well and implements requirement.Both save industrial chemicals, reduced working strength of workers, improved the result of use of the chemical displacement of reservoir oil again, reduced cost of production.
Description of drawings
Accompanying drawing is installation of the present utility model, use schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, the micro-flow liquid automatic allocation device has controller 12 and electromagnetic valve, distributes source and inlet to be communicated with electromagnetic valve and liquid by pipeline 13; Use control line 14 that electromagnetic valve is connected with controller 12.Chemical agent enters this device through liquid distribution source, opens motor operated valve by controller 12 successively by the time of setting, and makes chemical agent enter into each branch road successively, fully mixes with polymer solution at predetermined position, produces crosslinked under reservoir temperature.Electromagnetic valve is 1 or several, and inlet equates with the quantity of electromagnetic valve.This accompanying drawing diagram electromagnetic valve is 4, is respectively electromagnetic valve 4,5,6 and 7; Inlet also is 4, is respectively inlet 8,9,10 and 11, leads to each respectively and injects well head.The flow of each electromagnetic valve can need be regulated control by it by controller 12.Liquid distributes the source to be made up of storage tank 1, valve 2 and measuring pump 3, chemical agent is stored in the storage tank 1, through valve 2 and by arriving each electromagnetic valve after measuring pump 3 superchargings, electromagnetic valve 4,5,6,7 is under controller 12 controls, open successively by the time of setting, make chemical agent enter each branch road of inlet 8,9,10 and 11 successively and realize effective distribution.
