Abstract

Abstract.  Purpose.  For the cardinal decision of problem of the quality and effective boring drilling of horizontal, branch-hole and mining holes it is necessary: to investigate hydrodynamics of layer of petroleum and gas beds of different types; to inve stigate the tense state of the mountain breeds unsealed by mining holes and mechanism of forming of barrel the instruments of different types;  to  work  out  the  scientifically  reasonable  system  of  optimal  management  the  trajectory  of  the  boring  drilling  for  diffe rent geological  terms and methods of the boring drilling; to work out effective technology of the boring drilling, dissection of layers and fastening. For the analysis of possibilities of mining hole it is necessary to know the angles of incidence of layer and dire ction  of  angles of slope of the relatively immobile system of coordinates. The oriented selection of core sampler allows to obtain information about location of laying breeds, their permeability and porosity. An aim hired is development of methodology of determi nation of corners  of  spatial  orientation  of  core  sampler  and  its  layers  in  the  obl-directed  well  sites  mining  holes,  and  also  construction  of mathematical  model  of  oriented  selection  of  core  sampler.  Methodology.  An  inclinometer  measures  the projections  of  vectors  of  tension magnetic-field of Earth and acceleration of gravity on the orthogonal axes of boring projectile by means of three ferroprobes  and accelerometers for determination of magnetic azimuth zenithal and sight corners. An inclinometer allows no t only to determine spatial position of drill hole but also position of chisel that inflicts a mark on the body of core sampler. It gives an oppo rtunity at further laboratory research of core sampler to define spatial position of layers and cracks of core  sampler in relation to the vectors of  the free falling and tension of magnetic-field of Earth for renewal of spatial structure of layers of breed that surrounds a drill hole.  Findings.  It is suggested for determination of the state of soil under foundation  of building to use oriented selection of core sampler  with a stand-alone inclinometer. With the use of matrices of directing cosines got expression for determination of spatial position of  layers of core sampler.  Originality.  New in the decision of task of determination of structure of breed and laying layers is including in the complement of  selection of core sampler of stand -alone inclinometer  with electronic memory.  Practical value.  The use of  modern tools of measuring technique allows to design practically any technical processes us in an electronic kind, saving resources  and time the same on  realization  of these processes. The decision of scientific and technical task is carried out is creation of the  system of the oriented selection of s core sampler  in the obl-directed well sites  mining holes, that has an important pertaining to  national economy value in area of increase of efficiency of booty of oil.
