Annotation:

When operating wells, there occur a number of problems associated with high water flooding of the extracted product. Water flooding of wells can be caused by a violation of the integrity of the cement stone and the tightness of the casing strings, behind-the-casing flows, the rise of the OWC. This fact makes it necessary to carry out repair and insulation works (RIW). To date, the experience of using RIW states that the solution of most tasks during the performance of work depends on the qualifications of production personnel. This approach significantly limits the possibilities of increasing the effectiveness of the work being carried out. One of the ways to increase the efficiency of repair and insulation works is to build the design of the RIW. The design of the RIW is necessary in order to create automated systems for the possibility of real-time monitoring of both technological and economic efficiency of the use of a number of chemical products and technologies, as well as the design reflects the stages of RIW in wells and describes the main technological characteristics. This article discusses the calculation methodology for building the design of the RIW.
