COMPLICATION DURING WELL DRILLING AND THEIR PREVENTION

Abstract

The article provides a brief analysis of the complications that occur during the drilling of wells and their prevention. Violation of normal working conditions during drilling of wells occurs as a result of the impact of geological factors, disruption of technical and technological processes, as well as improper organization of work. Improper organization of work means a lack of manpower in the rig, failure to bring the necessary materials and tools to the rig, timely elimination of defects in the installation work. Due to technical failures of surface and wellhead equipment, long-term oil and gas-water fountains, as well as wells may be seriously complicated. Many complications occur as a result of incorrect technological process. These include the bending of the wellbore, the collapse of the well wall, the formation of a groove in the wellbore, and the occurrence of oil-gas-water through the protective belts. A lot of time and money is spent to prevent complications, which reduces the technical and economic performance of drilling. A number of measures should be taken in advance to prevent complications, as it is very difficult to prevent complications once they occur.
