The paper presents the results of studies on the qualitative and quantitative effect of filter capacity on the production performance of wells at the late stage of field development. Based on the actual field data, the distribution of filter capacity values by wells, as well as the dependence of oil, water flow rates and water cut on filter power was analyzed. Via a software program the equations describing these relationships were developed. The studies showed a decrease in oil production rate and increase in water cut with filter power. The limiting capacity of the filter, to which the operation is carried out with the most optimal flow rates and water cut, is specified. It is indicated that the main reason delaying the growth of production is the intensive flooding of formations, which is characteristic for fields at the late stage of development.
