The specific embodiment
Understand for technical characterictic, purpose and effect to the utility model have more clearly, contrast the specific embodiment of description of drawings the utility model at present:
Fig. 1 is the structural representation of two dispensing devices that are used for profile control of the utility model.Referring to Fig. 1; A kind of two dispensing devices that are used for profile control that the utility model proposes; It is provided with an injection pump 1; The output 11 of said injection pump 1 is connected in first end 21 of a tee junction 2, and 23 at second end 22 of said tee junction 2 and the 3rd end are connected with an intelligent electromagnetic flowmeter 3, a flow distributor 4 and a high-pressure check valve 5 in turn through pipeline respectively.When reality is injected profile control agent solution in well, so be provided with, can realize that an injection pump carries out the two well groups purpose of profile control simultaneously.
Wherein, Said pipeline includes movable bend pipe assembly 61 of a plurality of high pressure and straight tube 62; Wherein, Between the arrival end of second end 22 of said tee junction 2 and the 3rd end 23 and each said intelligent electromagnetic flowmeter 3, be connected through a movable bend pipe assembly 61 of a high pressure and a straight tube 62 successively respectively between the arrival end of the output of said flow distributor 4 and said high-pressure check valve 5, then be connected between the input of the port of export of said intelligent electromagnetic flowmeter 3 and said flow distributor 4 through a straight tube 62.Wherein, the internal diameter size of movable bend pipe assembly of above-mentioned high pressure and straight tube is preferably 2.5 writing brushes, and its concrete external form and length etc. can be decided according to actual working conditions.
In addition, the port of first end 21, second end 22 and the 3rd end 23 of said tee junction 2 further is provided with high pressure trip assembly in the ninth of the ten Heavenly Stems 7 respectively.Thus; When reality connects; First end of tee junction then is connected with the output 11 of said injection pump 1 through this high pressure trip assembly 7 in the ninth of the ten Heavenly Stems, and its second end, the 3rd end are then respectively successively through the corresponding connection of arrival end with each said intelligent electromagnetic flowmeter of the above-mentioned high pressure activity bend pipe assembly of this high pressure trip assembly in the ninth of the ten Heavenly Stems 7, one and a straight tube.
Further; The port of export of said high-pressure check valve 5 further is connected with one second pipeline; Said second pipeline is made up of one second straight tube 81 that connects successively and 82 of the movable bend pipe assemblies of one second high pressure, and the port of export correspondence of this high-pressure check valve 5 is connected in an end of this second straight tube 81.Through this second pipeline is set, so that the utility model is connected with well head in use.
Preferred embodiment be that said injection pump 1 is a twin-tub single-acting reciprocating pump.This twin-tub single-acting reciprocating pump has the slow-footed advantage of plunger motion, and is very little to profile control agent solution shear action.
A kind of two dispensing devices that are used for profile control for the utility model proposition; When implementing to use; The arrival end of said injection pump 1 is connected in a profile control liquid storage device, and makes the end of the movable bend pipe assembly of each said high pressure of the port of export that is connected in each high-pressure check valve 5 connect a well well head respectively; Profile control agent in the profile control liquid storage device flows into pressure-raising in said injection pump 1; Be divided into two through said tee junction 2, and inject into well via said intelligent electromagnetic flowmeter 3, flow distributor 4, high-pressure check valve 5 and second pipeline (the movable bend pipe assembly 82 of second straight tube 81 and second high pressure) successively through pipeline respectively.Wherein, 3 instantaneous deliveries that can monitor each take-off line of said intelligent electromagnetic flowmeter; And the not influence of liquid body density, viscosity, temperature, pressure and conductivity variations of this intelligent electromagnetic flowmeter certainty of measurement; Also be with RS485 or RS232 communications protocol simultaneously, can be directly and computer networking, be convenient to remote monitoring and operation.Through high-pressure check valve 5 is set, and utilize its permission medium, can prevent that profile control agent from flowing backwards to the characteristics that a direction flows; Promptly when in oil well, injecting profile control agent; Rely on profile control agent solution itself to flow, under the effect of a direction flowing fluid pressure, the flap of high-pressure check valve 5 is opened; When fluid flowed in the other direction, under the effect of fluid pressure and flap deadweight, flap was closed; Flow thereby cut off; Can control the flow direction of each branch's profile control agent solution, profile control agent is injected in the well the most at last, has ensured construction safety; This high-pressure check valve 5 is a prior art, and its structure is not done at this and given unnecessary details.
A kind of two dispensing devices that are used for profile control that the utility model proposes; Its simple in structure, reliable operation; Through injection pump, tee junction, flow distributor, intelligent electromagnetic flowmeter and the high-pressure check valve that sets gradually, can be implemented in same well site and use an injection pump that two well groups are carried out the profile control construction simultaneously, make full use of existing pump and annotated ability; Improve the operating efficiency of profile control transfer drive construction greatly, alleviated the contradiction that workload is big and equipment is not enough.
The above is merely the schematic specific embodiment of the utility model, is not in order to limit the scope of the utility model.Any those skilled in the art, equivalent variations of under the prerequisite of design that does not break away from the utility model and principle, having done and modification all should belong to the scope that the utility model is protected.
