【Abstract】 A mathematical model and a method to design the bit walk path for a slant well are presented in this paper. The designed results not only give a leading angle of azimuth at the well head, but also provide the planned values of all parameters at any point on the bit walk path. The research results show that rate of bit walk has different effects on every parameter. The examples are also provided to test and verify the correctness and universal applicability of the theory presented in this paper.更多还原
