FIELD: data processing.SUBSTANCE: invention relates to geophysics, to interpretation of materials of well geophysical researches (WGR) on stages of exploration and development of hydrocarbons and is intended to detect cracks. Carry out a research of the bench with different geophysical instruments with build-up curves of neutron gamma logging (NGL), gamma logging (GL), curves of apparent resistance (AR) potential of spontaneous polarization (SP). Presence of cracks is determined by the presence of synchronous extreme values, where synchronous deviation of GL and PS towards minimum values, AR - in any direction of extremum - open fractures. Synchronous deviation of GLand PS towards the maximum values, AR - towards the minimum values - closed fractures.EFFECT: technical result is ra eliable determination of fracturing zone and the presence of open and closed cracks for detecting with account of these data intervals of oil intake, water inrush.1 cl, 1 dwg |
