Equipment and technologies for improving the processes of transportation of drilled rock

Abstract

In this paper, an analysis of existing equipment for cleaning the bottom of the well from sludge during rotary drilling is carried out to find ways to improve the processes of transporting drilled rock. The article is devoted to the issue of improving the processes of transportation of drilled rock in the process of drilling oil and gas wells. Complications and accidents during the wiring of directional and horizontal wells are presented, the cause of which is insufficient well cleaning. The relevance of the task related to the development of highly efficient equipment and technologies for cleaning the bottom of the well from drilled rock is substantiated. An over-drilling device has been developed for cleaning vertical, inclined and horizontal wells from drilled rock. A schematic diagram of the work of the developed technical solution to improve the efficiency of cleaning the face and trunk of vertical, inclined and horizontal wells from drilled rock when drilling with a roller bit is presented.
