DETERMINATION OF PRODUCTIVITY COEFFICIENTS IN OBTAINING OIL-WATER INFLOWS FROM COMPLEX RESERVOIR ROCKS WITH TEXTURAL HETEROGENEITY

The article deals with the formation of flooded development objects at oil fields in the West Siberian sedimentary-rock megabasin. They are a direct result of the vigorous activity of geological processes in the bowels of the earth. A detailed analysis of the primary geological and field materials carried out by the authors of the article clearly showed that they began to form as a result of forced exploitation of deposits, when the current water cut of production wells sharply increases. As a result of the studies performed, the causes of watering of productive formations were identified and practical recommendations were proposed for conducting technological studies to reduce the watering of the well.
