The book describes the domestic experience of drilling with blowing exploration and explosive wells rotary method with the use of ball and blade bits, crowns with incisors of solid alloys, shot and diamond, as well as shock-rotating method with the help of slaughter blowers ; described the advantages and disadvantages of drilling with purged air, specified geological conditions favorable for the application of this method of drilling, the calculations for determining the air flow rate (gas) during drilling and pressure losses in the circulation system of wells. Special equipment and installations for drilling with purging are described, the schemes of tying the wellhead. are given. Particular attention is paid to drilling technology, to combat complications caused by water inflow. The features of drilling in conditions of perennial permafrost are considered, which is of interest for the study of northern regions and the development of deposits of Siberia. Determined the economic efficiency of this method of drilling. The book is intended for engineering and technical workers of drilling enterprises.
