Abstract
The article presents a methodology for calculating technological and design-operational parameters of oil displacement processes from the reservoir in the presence of sand production. A methodology for selecting the parameters of the optimal filtration regime has been developed, taking into account the effects of plunger rod pumping units, and an inequality has been derived to determine the filtration coefficient that ensures the maximum well flow rate without sand production. A physicochemical method for treating the wellbore zone to remove clay crust is proposed, as well as a chemical cleaning technology for the wellbore zone to enable further use of the filter and sand retention. It has been established that the efficiency of the filter in the sand sedimentation zone is determined by the optimal selection of its parameters. To enhance reservoir productivity under sand production conditions, the depression value should be set in such a way as to completely eliminate sand production.
