Improving the operational efficiency of drilling rock-breaking tools
Аннотация
Improving the quality and volume of drilling is the main condition for advancing the growth of reserves of raw materials of the national economy and industry. Rock-breaking tools are the main and busiest part of drilling equipment. Most of the operational productivity of drilling equipment depends on the operation of a rock-breaking tool, the improvement of the operational performance of which will reduce the cost of drilling wells and significantly increase drilling efficiency. The issues related to increasing the operational productivity of drilling equipment based on improving the design of rock-breaking tools have not been fully resolved, and their solution is now becoming important. This article presents the results of research devoted to the problems of reducing the efficiency of rock-crushing tools that arose as a result of high temperature at the bottom of the well when cleaning the bottom of the well by blowing air, as well as the sludge regime that occurs during drilling with cleaning with washing liquids prepared on the basis of water. Special attention is paid to improving the efficiency of drilling equipment by creating and implementing a rock-breaking tool design with high performance indicators.
