Slant-hole drilling rig, which can be used to drill inclined well from the ground, is used widely. During designing and research, it is very important to meet working reliability and requirement under various loads and working conditions. As for the complex structure of slant-hole drilling rig, we cannot get the real analytical solutions at present condition. Therefore, the paper establish the three-dimensional finite element models which are about the lifting process and working conditions of slant-hole drilling rig, study the applied loads of each working condition and analyze the stress-strain regulation of slant-hole drilling rig and its influential factor. Based on the analytical results of deformation and stress, an improvement scheme for the slant-hole drilling rig’s structure can is put forward.
