of dendrite growth process for binary Ni-Cu alloy with anisotropy of strong interface energy YUAN Xun-feng, DING Yu-tian (State Key Laboratory of Gansu Advanced Nonferrous Metal Materials, Lanzhou University of Technology, Lanzhou 730050, China) Abstract:Based on the Wheeler model and the Eggleston regularization technique of the anisotropy of strong interface energy, the phase-field model......
during vertical and fast drilling. High WOB leads to well deviation out of control, and low WOB leads to low rate of penetration (ROP). So considering the rock physical properties, the anisotropy index... to other oilfields. Key words: double-driven bottomhole assembly; vertical and fast drilling; critical weight of bit; elliptic deformation ratio; bit anisotropy 1 Introduction With the sustained and rapid......
