the inclined slip fault is an important structural deformation in the oil-gas-containing basin. The presence of pre-existing faults is an important reason for the widespread development of the cross-sliding faults, even in homogeneous rocks, when the horizontal principal stresses run diagonally to the pre-existing faults. When a large fault of a mountain making zone and a land boundary or a high-angle fault in a basement moves in the later period, the motion direction or the stress vector of the land and the boundary fault are always in an oblique rather than orthogonal relation. Oblique sliding is a common form of boundary-type fault or paleofracture resurgence and causes oblique fracturing of the basin. At present, due to the limitation of experimental conditions, the simulation of fracture multi-stage superposition deformation mostly focuses on exploring the control effect of the late stage slip effect on the deformation of the upper disc of the movable pre-existing fault, but the important influence of the late stage slip effect cannot be reduced.
