Summary of the invention
The object of the present invention is to provide coiled tubing to hang electric motor drive oil pump system process pipe string, realize rapid construction, carry out sea rountrip fast, meet the snubbing serving demand of marine electric pump well.
In order to reach above-mentioned purpose, the present invention has adopted following technical scheme, coiled tubing hangs electric motor drive oil pump system process pipe string, comprise and be enclosed within the main oil pipe in sleeve pipe and be enclosed within the coiled tubing in main oil pipe, described coiled tubing lower end is connected with oil rig, described main oil pipe lower end and coiled tubing outer setting have oil rig seating nipple, and oil rig is arranged in seating nipple, are also provided with cable and capillary tube in described coiled tubing.
Described main oil pipe is connected by docking adapter with seating nipple, described oil rig comprises motor, reducer, the electric pump connecting successively up and down, described electric pump below is connected with test barrel and imbibition cylinder in turn, and liquid sucting port is offered in the bottom surface of imbibition cylinder, between described test barrel and seating nipple, is provided with sealing drum.
Described seating nipple lower end connecting short section also arranges safety valve in junction, described pipe nipple lower end screen casing, and plug is installed in screen casing bottom.
Between described pipe nipple and sleeve pipe, be provided with twice packer from top to bottom, the packer of lower end is sand control packer.
Position, described seating nipple middle and lower part uniform Design has exhaust opening.
In described seating nipple, also pass and have liquid controling pipe line.
Compared to prior art, the present invention has following beneficial effect:
1. can realize not kill-job pump detection and workover; 2. realize producing fluid level monitoring, meet maritime safety production requirement;
operating speed is fast, improves offshore production efficiency; 4. avoid sewage link and environment hidden danger; 5. because coiled tubing has protective effect to inside cable, carry out ground detection and can again be with pump to be lowered to fast after qualified, saved time and operating cost.
This tubing string possesses safety valve and packer construction, by sharp work equipment, the coiled tubing that passes through cable and liquid controling pipe line is hung to downhole electric pump unit and goes into the well, and realizes down-hole secondary docking and controls safety valve and separate and produce liquid road, realizes electric pump and goes into operation fast.Because coiled tubing has protective effect to inside cable; carrying out ground detection can be with pump to be lowered to fast after qualified again; save time and operating cost, avoided the oil layer pollution and the sewage that due to kill-job, bring to return row's problem, met the demand of not kill-job, quick pump detection and workover.
