Description
Technical field
The utility model relates to a kind of chemicals dosing plant, and particularly a kind of well head pumps into chemicals dosing plant.
Background technology
In the oil exploitation process, especially add pluronic polymer for the ternary composite driving oil well, because the variation of temperature, pressure or inconsistent water mix, can cause stratum, pit shaft and pipeline surface fouling, affect crude oil production.The chemical method antiscale has advantages of that cost is low, successful, and the Main Means of solution is to add scale preventative.The adding of scale preventative is by well head antiscale chemicals dosing plant, chemicals dosing plant commonly used is agravic dosing, adds power and do not add the power chemicals dosing plant, these devices exist different shortcomings in dosing, as, energy consumption is higher, easily send out fault, maintenance difficult, and traditional unpowered chemicals dosing plant, efficient is low, affect crude oil yield, flexible poor performance etc.Especially northeastward regional, winter temperature is lower, the frozen block problem very easily occurs, and impact is produced.
Summary of the invention
The purpose of this utility model is to overcome shortcomings and deficiencies of the prior art, provides a kind of well head to pump into chemicals dosing plant.
Wellhead chemicals-feeder described in the utility model comprises explosive box, switch board, injection pump, strainer, fluid gate, sleeve pipe air defense gate, pipeline, valve etc.The drug storage casing is provided with content gauge, and inner bottom part is provided with closed heater, sensor, is connected with the fluid gate on the outlet at bottom pipeline, between fluid gate and injection pump connecting line strainer is set, and at the strainer pipeline sleeve pipe air defense gate is set; Be provided with three switches in the switch board: master switch, heater button and injection pump switch; The injection pump low side is provided with pressure relief opening, and the upper end links to each other with well head with pressure meter by ball-and-seat; Entering the injection pump pipeline at the explosive box fluid by the fluid gate is connected with injection pump and is provided with safety valve between the well head pipeline; Sleeve pipe air defense gate comprises outer side sleeve air defense gate and inboard sleeve pipe air defense gate.
The utlity model has good beneficial effect, simple in structure, easy operating, cost is low, is easy to safeguard, and flexibility is good, and dosing speed is controlled, and speed is fast.Built-in closed heater temperature is regulated and control by sensor, transmit temperature accurately, in time, can effectively avoid the generation of Cold Winter frozen block phenomenon, temperature adjusting is accurate, can not destroy the medicament composition because of excess Temperature, temperature is crossed the low frozen block phenomenon that produces affects oil extraction.Because the quantitative injection pump of pulse free is used in design, can not produce impact force to pipeline, prolong the application life of pressure duct connector and seal, can crude oil be sneaked in the chemicals dosing plant because of termination of pumping.
