Description

A kind of hollow hammer hole reverse circulation drilling structure
Technical field
The present invention relates to a kind of reacting cycle continuous coring drilling technology, relate to a kind of hollow hammer hole reverse circulation drilling structure specifically.
Background technology
Reacting cycle continuous coring drilling technology be a kind of when utilizing drilling well circulatory mediator return the technical method to earth's surface from shaft bottom cutting carring or rock core by drilling rod central passage, be referred to as CSR method abroad.The use of double-wall drill pipe is the most general, in addition also has individual layer and three layers of drilling rod.Circulatory mediator is pressed in well by two-tube annular space, returns, be in this way also called two-tube reacting cycle from interior tube hub passage cutting carring (heart).Divide from the circulatory mediator used, the method can be divided into again two large types: air (gas-liquid mixture) reacting cycle continuous sampling and hydraulic reverse-circulation continuous sampling.The drilling equipment that two kinds of methods use is substantially identical with drilling tool, but drilling technology is but similar not to the utmost.
Gas full well counterflush drilling technology, be also called hollow hammer hole counterflush drilling technology, the hollow hammer hole drill bit that have employed special development creeps into, its principle is that gas arrives shaft bottom along double wall drill tool, down-hole hammer and reverse circulation drill bit, and cutting carring (heart) reaches reacting cycle effect by drilling tool central passage being returned the circulating system formed to earth's surface.This technology is called as a revolution in drilling technique history.
Similar to gas full well counterflush drilling technology in reacting cycle continuous coring sample drilling technique principle, just the drill bit of the two is different, and there is an eccentric orfice at the bit central place of hollow hammer hole.The inclined hole of one 40 degree is got out, embedded with alloy column tooth at drill bit bottom side.Reacting cycle continuous coring drill bit is by impact and turn round bottom rock section fragmentation in the form of a ring, and the rock core got out is entered by drill bit bottom centre hole, and the impact of post tooth can force rock core to rupture.
Hollow hammer hole reacting cycle continuous coring sample drilling technology forms jointly by not stopping to bore acquisition rock core sample three kinds of technology continuously in the drilling well of down-hole hammer impact rotating detritus, the full well reacting cycle of fluid media (medium) and drilling well, is well-drilling technology leading in the world now.
Summary of the invention
In view of the defect that prior art exists, the object of the invention is to provide a kind of hollow hammer hole reverse circulation drilling structure.
