Description
Technical field
The utility model is related to oil gas well completion operation；Fracturing work and well cementation downhole tool technical field, are especially related to
And multistage a chain of Cut Block blocking device.
Background technology
Over more than 100 years, completion (well completion) is that in oil exploitation, open hole well is bored up to after design well depth,
The technique for making shaft bottom and oil reservoir be got up with certain fabric connectivity, is that drilling well works last important step, is petroleum production engineering again
Beginning, with later recover the oil, water filling and the exploitation of whole oil gas field it is closely coupled.And the quality of oil well completion quality is directly affected
To oily capacity of well and economic life, or even it is related to whole oil field and can be reasonably developed.
On modern wide variety of completion tubular column, for effective separate zone production, yield is improved, sliding sleeve to be also installed；It is former
The sliding sleeve come needs tripping in steel wire underground sliding bush switching instrument；Or cable underground sliding sleeve switching tools；Or coiled tubing underground is slided
Set switching tools are turned on and off.
Therefore, the related corollary equipment of sliding sleeve is able to extensive use, and underground sliding bush switching instrument is exactly switching sliding sleeve process
In one of wide variety of instrument.
Current underground sliding bush switching instrument both domestic and external mainly has two kinds of forms：
The first is by steel wire or cable, tripping in steel wire underground sliding bush switching instrument.The drawbacks of operation is to need steel
Silk winch and diesel powered unit, will there is ground steel wire preventer；Lubricator for slick line；Steel wire blowout prevention box；High-pressure hose, etc.
Ground installation；Also underground sliding bush switching instrument；Weighted lever；Mechanic jar or hydraulic shock device；Universal joint；Wire rope socket,
Add workload.
Second of continuous oil pipe operation；Tripping in coiled tubing underground hydraulic pressure sliding sleeve switch instrument.The drawbacks of operation is to need
Want coiled tubing；Diesel powered unit, will there is ground gooseneck power unit；Coiled tubing preventer；Ground face-pumping；High pressure is soft
Pipe, etc. ground installation；Also underground sliding bush switching instrument；Hydraulic release grip instrument；Hydraulic shock device；Weighted lever；Hydraulic pressure accelerates
