Description
Summary:The research purpose is to identify factors of premature flooding of wells, assess the influence of factors, simulate and compare results obtained with field data. An analysis of the reservoir properties, design and development indicators of horizontal wells showed that only 41% of cases of premature flooding are due to geological causes (heterogeneity of rock permeability). Technological reasons (high specific samplings) occur in 36% of cases, this problem is pronounced in wells where new technologies were implemented - division of the wellbore into sections using water and oil swell packers. In 23% of cases, premature flooding is due to wellbore drilling in the water-saturated zone.
