Description
technical field [0001] The present application relates to the technical field of oilfield development, in particular to a method, device, storage medium and electronic equipment for forming a formation pressure prediction model, and a formation pressure prediction method, device, storage medium and electronic equipment. Background technique [0002] Formation pressure refers to the pressure acting on the fluid in the rock pores, which can also be called formation pore pressure. Formation pressure is an important formation parameter in the process of oil and gas exploration and development, reflecting the flow capacity of oil and gas in the reservoir. During exploration, formation pressure can be used to establish fluid migration models, judge the effectiveness of traps and find favorable areas for drilling. During the drilling process, the accurate prediction of the formation pressure, especially the abnormal high pressure, can not only ensure safe and fast drilling, but al...
