Method for calculating influence value of fault and denudation line on formation pressure

The invention discloses a method for calculating an influence value of a fault and a denudation line on formation pressure. The method comprises the following steps: a, collecting data; b, the fault fall and the fault upward disappearing horizon serve as grading parameters to grade faults in the area, after grading, the influence coefficient of each stage of fault on the formation pressure is preset according to the fault grade, and meanwhile, the influence coefficient of a denudation line on the formation pressure is preset; c, establishing a calculation model of the influence value of the fault and the denudation line on the formation pressure; d, adjusting the preset influence coefficient of each stage of fault on the formation pressure and the influence coefficient of the denudation line on the formation pressure in a grading manner; and finally, substituting the influence coefficient adjusted when the correlation coefficient is the highest into the calculation model to obtain a calculation ...
