Development of a new composite material for bits of supporting and centering devices

Abstract

Research has been conducted on the development of a new composite material for bits of well-supporting and -centering devices. The highly durable composite makes it possible to reduce frictional energy losses on straightline wellbore sections while ensuring a highly destructive effect at wellbore sections that are being explored. High-carbon high-alloy cast irons reinforced with titanium carbide have been proposed as the composite matrix. It has been shown that the hardness of the new material is comparable to that of hard alloys, while the minimum power losses for sliding friction under abrasion are lower than for hard alloys and diamond-bearing materials.
