Automated control systems of the drilling process

Abstract

Automation of technological processes based on modern technics should ensure the intensification of production, improving the quality and reducing the cost of production. The automated drilling control systems as are SAOPB-1, Karat-2, ASUTP-B, ALMAZ, etc. were considered. This allowed to classify these systems according to their functional purpose: stabilization of feed rate, control of drilling parameters and flexible production system. Four classes of control systems are distinguished depending on the complexity of geological and technical conditions for drilling boreholes. The first class includes the systems for stabilization of the feed rate, the second - designed to implement relatively simple algorithms for controlling the drilling process, the third - oriented to work in complex and poorly studied geological and technical conditions, the fourth - capable of operating in automatic modes for deepening the borehole and for tripping operations. It is shown that the most technological is the implementation of a set of technical facilities capable of operating in automatic modes during borehole deepening and carrying out tripping operations
