The lower end of the oil pipe is connected with an underground safety valve, the lower end of the underground safety valve is connected with a cable-passing packer, the lower end of the cable-passing packer is connected with an automatic flow divider through the oil pipe, the lower end of the automatic flow divider is connected with a check valve, the lower end of the check valve is connected with an electric submersible pump, the lower end of the electric submersible pump is connected with a magnetic scale preventer, the lower end of the magnetic scale preventer is connected with the oil pipe, a centralizer is fixed on the oil pipe at the lower end of the magnetic scale preventer, and the lower end of the oil pipe at the. The effect is as follows: the self-spraying, lifting, well-flushing and well-killing operation of the pipe column can be completed in one trip. The underground Y-shaped electric pump lifting pipe column is replaced, the underground pipe column structure is simplified, the combined operation of self-spraying and lifting in the beach area is realized, the initial investment of exploration and development is reduced, the engineering construction speed is accelerated, the investment recovery is accelerated, and the investment risk is reduced.
Description
Technical field
The utility model relates to the formation testing pilot production technology of petroleum geology exploration and exploitation, and particularly the connection that adopts one-trip string to finish blowing and electric pump lifting is made special-purpose down-hole string.
Background technology
What adopt in the formation testing pilot production process of oil exploration and exploitation at present, is Y type electric pump lifting tubing string.The complex structure of Y type electric pump lifting tubing string, the wellhead assembly of Pei Heing is also very complicated with it.Y type electric pump lifting tubing string is in the use of down-hole, complex operation, should not operate, and a complete set of equipment and instrument all need be introduced, execute-in-place also must carry out the technological guidance by foreign side, blowout preventer can't be installed in the whole operation process particularly, potential safety hazard is big, cost is high.
The utility model content
The purpose of this utility model is: provide a kind of blowing and lifting connection to make tubing string, replace present Y type electric pump lifting tubing string, simplify tubular column structure, the blowing and the electric submersible pump connection of realization Haiti, beach district oil gas well are constructed, and adopt one-trip string to finish operations such as blowing, lifting, well-flushing, kill-job.
The technical solution adopted in the utility model is: blowing and lifting connection are made tubing string, mainly by horn mouth, centralizer, the magnetic scale control device, submersible electric pump, ball-and-seat, automatic flow divider, cable-passing packer, storm valve, liquid controling pipe line and cable are formed, it is characterized in that: the lower end at oil pipe is connected with storm valve, on the inlet of the upper surface of storm valve, be connected with liquid controling pipe line, the lower end of storm valve connects cable-passing packer, on the inlet of the upper surface of cable-passing packer, be connected with liquid controling pipe line, the lower end of cable-passing packer is connected with automatic flow divider by oil pipe, automatically the lower end of flow divider is connected with ball-and-seat, the lower end of ball-and-seat connects submersible electric pump, pass cable-passing packer for submersible electric pump provides the cable of electric energy and transmission test signal, be connected with submersible electric pump.The lower end of submersible electric pump connects the magnetic scale control device, and the lower end of magnetic scale control device connects oil pipe, is fixed with centralizer on the oil pipe of magnetic scale control device lower end, is connected with horn mouth in the oil pipe lower end of magnetic scale control device lower end.
A whole set of blowing and lifting connection are made the tubing string G.I.H, and bell-mouthed position should be on the top of oil reservoir.Centralizer, magnetic scale control device and horn mouth belong to auxiliary downhole tool, assist to finish operations such as oil recovery, well-flushing, kill-job.Storm valve and cable-passing packer belong to the downhole safety parts, play protection down-hole string safety effect.Submersible electric pump and ball-and-seat are the main underground components that recovers the oil and produce, and finishing recovers the oil produces.Automatically flow divider is the critical piece of well-flushing, uses in the west longitude process.Blowing and lifting connection is made tubing string can realize that one-trip string finishes operations such as blowing, lifting, well-flushing, kill-job.
The beneficial effects of the utility model: the utility model blowing and lifting connection is made tubing string, can realize that one-trip string finishes blowing, lifting, well-flushing, kill job.Replace down-hole Y type electric pump lifting tubing string, simplify the down-hole string structure, realization Haiti, beach district's blowing and lifting connection are constructed, reduce the investment of exploration and initial stage of development, accelerate engineering construction speed, accelerate investment and reclaim, reduce investment risk, improve sea, beach oil field prospecting exploitation whole economic efficiency.
