Designing of a turbo-drill turbine of increased power in case of drilling by means of diamond drill-bits
The article considers concept of designing new turbines for turbo-drills. The advantage of traditional approach with account of contemporary view on power characteristics of a turbo-drill, designed for operation with diamond drill-bits, is shown. Some results of field testing of a new power-increased turbine designed for drilling of deep wells by diamond drill-bits in case of usage of high-density drilling mud are submitted.
