摘要：The relationship between ξ potential of near surface of rock and rock-breaking efficiency in recent years were reviewed. Based on the microscale of crystal lattice, the influence of cataclysmic change of induced dipole on ξ potential of near surface of rock core in the process of rock failure was investigated. The effect of changing potential on the hardness of near surface of rock was analyzed. The results indicated that ξ potential of near surface of rock could be changed suddenly by induced dipole from the crystal lattice of rock core caused by microfracture extension. In addition, the rock-breaking efficiency could be improved by changing ξ potential of rock surface. This study can be helpful for the design of novel additives for drilling fluids, and endow with economically and technically viable petroleum development and production processes.
