| Abstract: | When the course of drilling a borizontal well with the downhole motor, under the axial force and deadweight, the lateral uniform distributed load and the original bending were simultaneously act upon the bottom - hole assembly. The state matrix method is proposed to solve the complex problem of mechanics in this paper. Its result is agreed with other methods and corresponded to practise. |
