The purpose of this utility model is realized by following technical scheme:
A kind of pipe of the Y with hydraulic control sliding sleeve electric submersible pump producing tubular column, comprise: upper and lower two different-diameters the first sleeve pipe connecting together and the second sleeve pipe, be sleeved on production tube in the first sleeve pipe and the second sleeve pipe, be arranged on successively storm valve, Y-shaped connector, location sealing, production sliding sleeve, layering sealing in production tube from top to bottom, be located in joint, guider; It is characterized in that: a hydraulic control sliding sleeve is installed on the top of location sealing, and this hydraulic control sliding sleeve is directly connected with aboveground Hydraulic Station by liquid controling pipe line; One end of Y-shaped connector by a seating nipple be connected with blanking plug, the other end of Y-shaped connector is connected with electric submersible pump; By the above-mentioned field produces tubing string that connects and composes.
Described hydraulic control sliding sleeve is: the sliding sleeve of hydraulic control switch, and hydraulic control sliding sleeve is on the position between location sealing and Y-shaped connector.
The both sides of described production sliding sleeve are provided with sand-proof pipe; The both sides of being located in joint are provided with stopping step.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, it provides the mode of high pressure liquid force feed to control the switch of hydraulic control sliding sleeve by ground hydraulic station to hydraulic control sliding sleeve, when ground fluid pressure drop after, hydraulic control sliding sleeve can be closed automatically, block formation fluid and flow to oil jacket annular space inside, thereby, reached control formation fluid object; Because it does not need to arrange on flow string cable-passing packer again, not only simplify the structure of Y pipe electric submersible pump producing tubular column; And, also improved the reliability of Y pipe electric submersible pump producing tubular column; Meanwhile, in the situation that guaranteeing that tubing string meets country to electric submersible pump producing tubular column security regulations, can also save the parts such as sliding sleeve or pipe with holes, greatly save production cost.
