Description
Technical field
This utility model relates to oil field development technical field, particularly to a kind of oil-water well sand bailing process tubing string.
Background technology
Oil field enters mid-later development phase, the oil reservoir of loose cementation, shakes out increasingly severe, and oil well occurs that sand buries oil reservoir
After, cause the oil well underproduction even to stop production；Meanwhile, after sand production in oil, stratum is the most in debt, along with continuous expansion in debt
Oil reservoir is caused greatly to cave in.If formation pressure is low or misses serious oil well, sand cannot be gone out by well sand washing at all.
At present, the sand bucket that oil field uses carries out dragging for sand, although achieves successfully, but still suffers from card and drag for sandpipe post, drag for sand
Not thoroughly, the drawbacks such as sand efficiency is low are dragged for.
Summary of the invention
In view of this, this utility model is directed to provide a kind of oil-water well sand bailing process tubing string, and this tubing string can be born
Pressure drags for sand, reaches to improve and drags for sand efficiency and the purpose of technique success rate.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of oil-water well sand bailing process tubing string, including oil pipe, packer, travelling valve, dragging for sand, to control switch, sand pumping device total
Becoming, drag for sand shovel, oil pipe lower end connects packer, packer lower end connects travelling valve, sand control is dragged in the connection of travelling valve lower end
Switch, drag for sand control switch lower end connect sand pumping device assembly, sand pumping device assembly lower end connect drag for sand shovel；Oil pipe, packer,
Travelling valve, drag for sand control switch, sand pumping device assembly, drag for sand shovel link into an integrated entity after under enter in sleeve pipe.
Further, oil pipe, packer, travelling valve, drag for sand control switch, sand pumping device assembly, drag for sand shovel between be spiral shell
Stricture of vagina connects.
Further, described this outer diameter of oil pipe is 73mm, and interior diameter is 62mm.
Further, described packer is 1341 type packers, and this packer maximum outside diameter is 114mm, imperial palace latus rectum
For 62mm.
Further, the travelling valve bulb diameter in described travelling valve is 39mm.
Further, described sand pumping device assembly external diameter is 108mm.
Further, dragging for sand shovel maximum outside diameter described in is 114mm.
Relative to prior art, a kind of oil-water well sand bailing process tubing string described in the utility model has a following advantage: this practicality
Novel a kind of oil-water well sand bailing process tubing string, after packer setting, packer and oil well casing are formed between plunger and pump barrel
Piston relation, simple, convenient；Technique success rate 100%, drags for sand effective percentage 100%.
