TECHNOLOGY OF REDUCTION OF SAND PRODUCTION IN OIL WELLS

Abstract

The article presents the main causes of water and sand production in oil wells, the consequences of forma-tion of sand plugs and also the methods of prevention of this type of problem. The authors developed the method of reduction of sand production in oil wells. The distinguishing feature of developed method from known ones is the creation of sand filter directly inside the oil well. For effective selection of proppants as applied to geological and physical conditions of wells the authors developed a software «Proppants», which is a database on physical and mechanical and filtration properties of proppants.
