Abstract

The article describes a method for eliminating the problem of freezing of the hydraulic system of the URB-2A2 drilling rig when drilling exploration wells in the freezing conditions of the Sakha Republic (Yakutia). During the study, we analyzed the long-term experience of industrial companies engaged in drilling operations in Yakutia. In this regard, in the regions of the Far North, an important task is to develop innovative methods aimed at improving the working conditions of workers and the quality of technologies for protecting the hydraulic systems of drilling rigs operating in the harsh climate of the region.

As a measure to prevent and combat freezing of the hydraulic system, we propose insulating the hydraulic equipment of the drilling rig using heat-insulating materials. Based on the diagnostics and calculations, we were able to develop an effective way to solve the problem of freezing of the hydraulic system. This method does not require significant changes in the existing equipment and does not entail large financial costs. At the next stage, we will test the proposed method for solving the problem in the conditions of the Far North on the URB-2A2 self-propelled drilling rig.
