METHOD OF DETERMINING LITHOLOGIC ROCK COMPOSITION DURING DRILLING

摘要

The object of the invention is to reduce losses,process simplification and site determinationopening the layer in which it is determinedlitologloké composition, forming this layer.SUMMARY OF THE INVENTION: The drilling solution is preparedwith a stable redox-potenoial valueand is fed to the borehole in which it performsone circulating circulation, the redox potential is measureddrilling solution emergingfrom the borehole and determine the mineralogical compositionopened layers by comparing the valueand the direction of deviation of the redox drilling potentialsolution with known, normal redox-potentials of minerals that form sedimentarylayer.
