DEFINITION METHOD OF VERTICAL AND HORIZONTAL SPECIFIC RESISTANCE, AND ALSO ANGLES OF RELATIVE INCLINATION IN ANISOTROPIC GEOLOGICAL MATERIALS

摘要

FIELD: mining.;SUBSTANCE: invention relates to measurement of parametres of geological materials in drill hole. Measurements are implemented by means of combination of orientable three-element explorers (sensors), moved in well, on several frequencies at different azimuth angles at particular depth during rotation of well-logging device. It is implemented extrapolation of measurements effects for value, received on zero frequency. There are discrupted measurements effects for azimuthal elements of sampling. For each sensor there are presented measurements effects of corresponding function of angular positions of well-logging device. On the basis of existing corresponding functions it is defined property of geological material. For several measurements effects at particular depth and azimuthal orientation there can be assigned weighting coefficients with receiving of averaged quantity.;EFFECT: reduction of uncertainty of effect, ability of identically decide orientation of main axis of anisotropy, and consequently - horizontal and vertical specific resistance, and also incline.;24 cl, 12 dwg
