Abstract
The utility model relates to an oil well oil production auxiliary apparatus, which is a device used for adding medicine into a borehole. The utility model is mainly composed of a liquid storage tank and a medicine adding tank, pipelines, a valve, and a pump arranged between the liquid storage tank and the medicine adding tank, and high-pressure pipelines, a valve, and a flowmeter installed on a trailer arranged between the medicine adding tank and a well head. The utility model can make chemical medicine added in the annular space of an oil sleeve of the oil well without using a power pump and has the advantages of difficult damage, high efficiency, and low cost.
Description
The utility model relates to a kind of well recovery ancillary service, is a kind of device that adds medicament in pit shaft.
Contain more wax, colloidal bitumen in the output liquid of some oil well, make its freezing point lower, lower in the upper wellbore temperature, wax or colloidal bitumen just condense in oil pipe or the well head easily, influence the ordinary production of oil gas well.For head it off, the normal method that adopts the clear cured viscosity reduction of chemistry is normally carried out to keep to recover the oil to produce.Paraffin removing with chemical method is exactly the chemical agent that can reduce wax in viscosity of crude, the dissolving crude oil, slowly adds in the oil sets annular space of production well, make chemical agent and output liquid organic molten and, reach the purpose that changes its freezing point.Owing to all have certain pressure in the oil sets annular space of oil well,, the chemical agent in the fluid reservoir injected in the pit shaft by pipeline at the present normal device that adopts the motor drives kinetic pump.This method needs bigger power, and fault is many, and cost is also high.
The purpose of this utility model is a kind of paraffin removing with chemical method of oil gas well, viscosity reduction equilibrium method chemicals dosing plant that does not need power set of design, utilizes it can reduce fault, reduces cost.
Technical solution of the present utility model is to realize like this, the paraffin removing with chemical method of a kind of oil gas well, viscosity reduction equilibrium method chemicals dosing plant, link together by fluid reservoir 3 and pipeline and to constitute, its special character is, (1) fluid reservoir 3 is connected with grug feeding jar 8 by pipeline 6, and valve 14, dosing pump 15 are installed on pipeline 6; (2) grug feeding jar 8 is connected with well head 10 by pipeline 11, and flow meter and by-pass valve control are installed on pipeline 11.
In above-mentioned technical solution, its special character is that also the pipeline diameter between grug feeding jar 8 and the well head 10 is 60 millimeters-100 millimeters, and length of pipeline is 0.5 meter-3.5 meters.
In above-mentioned technical solution, its special character also is, flow meter 16, strainer 17 and valve 18 also are installed on pipeline 6, between pipeline 6 and fluid reservoir 3 valve 4 is installed, and on the tank body of grug feeding jar 8 double colored indicator is installed.
The utility model has the advantages that (1) does not need kinetic pump during dosing in well, do not require the expenditure of energy energy conservation; (2) owing to adopt equilibrium method in well, to add medicament, there is not moving component, not fragile, be difficult for breaking down, the efficient height, cost is low.
Accompanying drawing is the syndeton schematic diagram that the utility model and well head link together.
Be described further (embodiment) below in conjunction with accompanying drawing.
Grug feeding jar 8 is a pressure vessel, and its design pressure is 0.1--16MPa, 0.8 meter of diameter, and high about 1 meter, have pore 9 in the tank top, double colored indicator is installed on tank body.Fluid reservoir 3 is a non-pressure vessel, and capacity is about 6 sides, has pore 2 above fluid reservoir 3, has sewage draining exit and blowoff valve 1 in its bottom.Be connected by pipeline 6 between fluid reservoir 3 and the grug feeding jar 8, pressure meter 5, valve 14, pump 15 and flow meter 16, cleaner 17 and valve 18 are installed on pipeline 6, valve 19 is installed below valve 18.Pipeline 7 directly is communicated with grug feeding jar 8 and fluid reservoir 3.Grug feeding jar 8 is connected with pipeline 11, and (i.e. 21/2 "), length is 1--2 rice (this pipeline is short more good more) for preferably 63.5 millimeters of the diameters of pipeline 11.Flow meter 12, valve 13 are installed on pipeline 11, and valve 13 and valve 14 adopt high pressure valve, and pipeline 11 and pipeline 6 adopt high pressure line.Pipeline and valve 4 are installed between fluid reservoir 3 and pipeline 6, said apparatus is installed on the trailer, constitute a cover head, be convenient to move and transportation.
Fill chemical agent with adding in the fluid reservoir 3, fully mix, can close valve 14,19, valve 4,18 is opened, start pump 15, make the chemical agent in the fluid reservoir 3 carry out partial circulating for making chemical agent.This device is hauled by the well mouth of oil well, pipeline 11 and well head 10 are linked together, as the case may be, pipeline 11 also can be selected high-pressure hose for use.Valve-off 4,19 and 13 is opened valve 18,14, and primer pump 15 is driven into 3 chemical agent in the fluid reservoir in the grug feeding jar 8, and valve-off 14 separates fluid reservoir 3 and grug feeding jar 8.Open valve 13, grug feeding jar 8 and well head 10 are communicated with, form a pressure system that constitutes by grug feeding jar 8, pipeline 11, oil gas well ring set space three parts, make the pressure balance in interior oil sets annular space of pit shaft and the grug feeding jar 8, chemical agent in the grug feeding jar 8 is in higher position, and under same pressure, chemical agent can flow in the pit shaft, by adjusting valve 13, can control the speed of dosing in well.
