坚硬“打滑”地层孕镶金刚石钻头设计与选用

Design and Selection of Impregnated Diamond Bit in Hard and Slipping Formation

摘要:

坚硬“打滑”地层钻进一直是钻进工作的一项难题，深入分析了钻进碎岩机理，确定影响钻进速度的因素，进而提出钻头设计应考虑的因素，并通过野外试验验证了所提观点。

Abstract:

Drilling in hard and slipping formation has been difficult, the paper analyzed drilling fragmentation mechanism to determined the factors affecting drilling rate, and put forward the factors that should be considered in bit design with field tests.
