Design of computerized controlled systems for directional laying of engineering communications

Abstract

The subject of research and development is the technology of directional laying of engineering horizontal inclined wells intended both for exploration drilling and for laying engineering communications by the method of static puncture, as well as installations for their implementation. Laying engineering communications in urban and industrial environments is a common problem, and the existing technologies do not fully meet the increased requirements for the accuracy of working out the specified trajectories and efficiency of wells development. Laying engineering communications through water barriers is a special issue. The proposed method is based on the prompt installation of the forward end of the whipstock barrel in the required position for controlled correction of the trajectory of the well being laid. The main disadvantage of existing methods is the use of only passive trajectory control of the working body and the absence of control systems for the main processes of laying wells. The proposed system includes a guided barrel, a computerized control and management system being the basis for developing a technology for laying directional wells of small diameter and complex profile. The considered technology is the simplest and most economically profitable in comparison with drilling and punching. The possibility of using the described developments including for the purpose of directional drilling has been substantiated.
