Technical field
The utility model relates to field produces tubing string, relates in particular to a kind of pipe of the Y with hydraulic control sliding sleeve electric submersible pump producing tubular column that utilizes ground hydraulic to realize flow string underground hydraulic-control.
Background technology
As shown in Figure 1, existing flow string comprises: upper and lower two different-diameters the first sleeve pipe 6 connecting together and the second sleeve pipe 18, be sleeved on production tube 1 in the first sleeve pipe 6 and the second sleeve pipe 18, be arranged on successively storm valve 3, cable packer 5, Y-shaped connector 7, pipe with holes or sliding sleeve 10, location sealing 11 in production tube 1 from top to bottom, produce sliding sleeve 12, layering sealing 14, be located in joint 15, guider 17; Wherein, a cable penetration device 4, cable penetration device 4 being installed on cable packer 5 is to realize power cable 2 to pass through cable-passing packer and be connected with Surface power drive system; Y-shaped connector 7 is connected with electric submersible pump 9; Storm valve 3 is provided with control pipeline 19, this control pipeline 19 of being connected with aboveground control system and is also connected with vent valve 20 simultaneously; By the above-mentioned field produces tubing string that connects and composes.
Y-shaped connector 7 bottoms of above-mentioned flow string install pipe with holes or sliding sleeve 10 additional, with thinking that formation fluid provides the passage that flows into electric submersible pump 9 intakes; The object that Y-shaped connector 7 tops of flow string install cable-passing packer 5 additional is in order to meet flow string annular space well control demand; Meanwhile, the blanking plug that is connected with a seating nipple and is used in conjunction with this seating nipple in Y-shaped connector 7 bottoms.Because cable-passing packer need to carry out setting, deblocking work, its deblocking pulling force is larger, has increased the risk of deblocking; And due to the existence of cable-passing packer, also to washing kill-job, bring higher pump pressure, not only make discharge capacity be restricted; While meanwhile, also making power cable 2 pass through cable-passing packer 5, easily break down.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of Y with hydraulic control sliding sleeve to manage electric submersible pump producing tubular column, 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 hydraulic provides pressure to hydraulic control sliding sleeve, sliding sleeve is held open; After ground hydraulic releases, hydraulic control sliding sleeve can be closed automatically, and block formation fluid and flow to oil jacket annular space inside, thereby, reach control formation fluid and flow to oil jacket annular space 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.
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.
