Research on Diamond Drilling Theory

Abstract:

Drawn upon the experiment and the experience home and abroad, the drilling criteria which is based on the control of the bit penetration amount is proposed to achieve optimum drilling performance. According to the principle of increasing the penetration value, it is necessary and possible to develop quality large size PCDs so as to transcend the limitation of existing diamond drilling. The status quo of the technique is reviewed, and the significance of beefing up scientific experiment and research is emphasized.
