Description
Technical field
The utility model relates to geological drilling technology field, especially a kind of orientation coring automatic localization device.
Background technique
Currently, in geological drilling field, directional drilling mainly use bottom outlet motor driving drill bit fractured rock obtain into
Ruler, due to be bottom outlet motor driving, drilling rod be it is non-rotary, be intended only as high pressure water pipeline and send high pressure water to bottom outlet, by
High pressure water-driven bottom outlet motor rotation, and then drive bit.The straight line of measuring device in the bus and drilling rod of tool face azimuth
It is fixed and invariable, therefore wired or wireless with boring no matter when instrument puts into and can accurately find tool face azimuth in drill pipe bore
Bus, to measure the technical parameters such as the tool face azimuth of drill bit, azimuth, apex angle.The directional drilling of this downhole motor is not
Foot place is that complete effective rock core cannot be obtained, and then cannot obtain accurate geological information.
Currently, core drilling is typically only capable to coring in vertical direction, and can not be along other in geological drilling field
The direction coring of setting because during core drilling, drilling rod be it is high-speed rotating, the angle moment is all changing, not
The bus that bit tool face angle cannot be found in the angle of disconnected variation, is also just unable to measure out tool face azimuth, the azimuth of drill bit
And the technical parameters such as apex angle.I.e. core drilling is disadvantageous in that the coring that can only realize vertical direction, can not achieve other
The coring of direction initialization.
Currently, realize that orientation core drilling is necessary in geological drilling field, by taking construction of subway as an example,
It before construction of subway, needs to be spaced the multiple sample points of setting on programme path, carries out the coring of vertical direction in each point,
To understand sliver road rock stratum distribution, for subsequent setting subway dig depth and subway work technical solution provide it is theoretical according to
According to theoretically the sample point the more more can react the rock stratum distribution of sliver road, but because of ring in city underground construction process
Border and territory restriction can not accomplish intensive setting sample point, also, the sampling in vertical direction is " point sampling ", nothing always
Method obtains the geological information persistently to link up along planning route horizontal axis direction.
