Abstract: The mechanical analysis of bottom hole assembly(BHA) is the basis of BHA's design and well-path control in oil and gas drilling engineering. ``Beam-column theory'' is a typical and effective method in practice, but its application is limited for not solving the initial bending problems. A method, as known as equivalent loading method, for solving beam-column with initial bending is discussed in this paper. The method has been used successfully for solving practical problems in drilling engineering and provides theoretical foundations for downhole tool design and well-path control. Conclusions are given in this paper.
