Applied implementation of digital expert systems in the process of planning and designing repair and insulation works in oil wells

Abstract

During the operation of producing oil and gas wells, oil from formations is extracted together with water. In the case of a significant water cut in a well it is economically feasible and technologically necessary to carry out geological and technical actions (GTA) with the aim to reduce the water cut - repair and isolation works (RIW). Designing actions for RIW is associated with a analysis of the reasons of increase of water cut and the development of methods for eliminating the identified problem. The use of expert systems makes it possible to implement an integrated approach to the design of actions for RIW with a choice of necessary compositions, and designs of works, taking into different processes. Keywords: expert system; repair and insulation works; optimization; design.
