Reservoir pressure is reduced because the intensification of the selections and low compensation fluid withdrawal injection. Engineers have made a program to increase injectability, but there is a problem. This problem is a short duration of effect it after well-workover operation (acid treatment, hydraulic fracturing). Technological mode of injection wells and planned task is not meting. The design pressure injection is 21.5 MPa. Injection wells is not taking because of the the effect of field-geological characteristics terrigenous reservoirs. For example, the field-geological characteristics is wettability. Important information for terrigenous reservoirs is to analyze the distribution unit electrical resistance oil reservoir. If the whole of the Perm regeon unit electrical resistance for terrigenous reservoirs is range from 1 to 100 ohm · m, then deposits Solikamskaya depression set anomalous resistance, which can exceed 1000 Ohm · m. High unit electrical resistance indicate either low water saturation of the porous medium or the absence of an aqueous continuous phase, which can occur in hydrophobic systems. Analysis of the impact unit electrical resistance on the injectability terrigenous reservoirs carried out for Unvinskoye field. The data lateral logging have used for to construct map the distribution of unit electrical resistance.
