硬岩钻进用石油钻头研究现状及发展趋势
Current Status and Tendency of Research on Oil Bits for Hard Rock Drilling
摘要
Abstract
Continued safe supply of energy and mineral resources is a guarantee for rapid economic growth, while hard rock drilling limits the development of deep oil drilling. In geological drilling, diamond bits are usually employed to solve this problem; and in oil and gas drilling, polycrystalline diamond compact (PDC) bits have been used in recent years besides conventional roller bits and diamond bits. This paper presents the applications of roller bits, diamond bits, PDC bits and percussion — rotary bits for hard rock drilling Thereinto, studies of roller bits mainly focus on improving the bearing seal performance , distribution and strength of cutters, and that of diamond bits focus on rock broken mechanism, diamond parameters & matrix performance, and bit structure. We propose the research direction and tendency for each kind of bits to provide references for the development of hard rock drilling technology.关键词
