DRILLING OF COMPLEXES WITH HYDRAULIC TRANSPORT OF A CORE FOR INCREASE OF EFFICIENCY OF GEOLOGICAL EXPLORATION WORKS

On the basis of an in-depth analysis domestic achievements and results experimental methodological works practice expediency widespread use improved technical means technologies for drilling geological exploration wells with complexes counterflush coring (CCD) till depth 300 m upon sedimentary strata is substantiated. During brown coal deposits titanium placers, which convincingly confirm high efficiency CCD appropriate modifi cations equipment, technology testing methods specific productive horizons host rocks. The best industrial application were obtained during Paromivske ilmenite placer deposit (2016). High economic indicators completion work in difficult socio-economic conditions achieved thanks to application. main argument favor undoubtedly proven by ultra-high productivity a significant reduction cost quality work. operational informational content method allows timely adjustments responsibly choose most optimal flexible schemes research. Due significantly reduced timing operations, field research can be carried out shorter at favorable climatic seasons agricultural activity. mobile circulation system excludes construction earthen sedimentation tanks, signifi cantly reduces size disturbed soils, their contamination prevents loss flushing fluid. peculiarities organization promote close cooperation, mutual control understanding technical, geological, geophysical other personnel serving actively mobilize high-quality highly efficient performance tasks. A heavy operations technological process improves working service personnel, increases production culture, contributes attractiveness profession. Ukraine has sufficient facilities (at Kiev Drilling Equipment Plant, Dnepropetrovsk Discovery - Equipment. LLC, etc.), are capable providing companies modern CCD. reasons that hinder development recognized ways solve problem introduction featured.
