Description
Technical field
The present invention relates to underground work devices, bore plug-drifting-more specifically to a kind of scraper controllable type and scrape wall one
Body formula device and operation technique method.
Background technique
Casing scraper can be used for remove remain in cement block on internal surface of sleeve pipe, cement sheath, hard wax, various saline crystallizations and
The objects such as generated iron oxide after deposit, perforation burrs and casing corrosion, so as to the various works of going into the well of unblocked ground tripping in
Tool.Especially when the tool of going into the well and internal surface of sleeve pipe annular space are smaller, more in abundant scraping and then lower step construction should be carried out.
When current domestic some oil fields and external oil and water well construction operation, a kind of essential process is had become using scraper,
Its object is to improve the success rate of tool tripping in and operation.Such as packer sets success rate etc..
Drifting at present scrapes wall usually after the completion of well cementing operation, and by drilling rod under former drilling machine point, tubing string is completed twice, and
And not can be recycled after scraper stretching, operating efficiency is lower, and duty cycle is long, costly.In shale gas horizontal well gas testing
Journey generally can not carry out kill-job operation, therefore the Operating Pressure technology based on coiled tubing obtains extensively in shale gas development process
General application.And continuous oil pipe operation technology have can progresss lower oil tube operation with pressure, construction efficiency height, overall cost it is low etc.
Advantage.But coiled tubing is lower in the mechanical pressure that horizontal segment going down process can apply, and the existing wall scraper of mesh is not able to satisfy scene
Job requirements.Need to develop a kind of applicable coiled tubing, decentralization process is low with pit shaft frictional resistance, and lift pipe string meets the small drifting of card risk
Scrape wall tool.
