The relevance of the work is determined by the fact that Russian oil and gas companies are faced with the task of creating domestic information and measurement systems used in the process of drilling directional and horizontal wells. The presented article discusses the experience of implementing a high-tech complex of instruments and devices, which allows solving the problems of determining the expanded composition of hydrocarbons in the drilling fluid, sludge and core, ensuring the optimal mode of drilling and opening productive formations, monitoring the cleaning of the bottom of the wellbore and identifying rock fall intervals. The prospects for using a preparation system for gas analysis (constant volume degasser) and a gas analyzer unit are shown. A unique intelligent video monitoring system for drilled rock volume is described, which allows replacing expensive imported slurry weighing machines.
