MODELING THE INTERACTION OF HYDRAULIC RIPPING CRACKS IN COMPLEX CRACK SYSTEMS

摘要

1. The method of performing the hydraulic fracturing operation at the location of the well, the location of the well is in an underground formation having a borehole and a fracture system, the fracture system contains natural fractures, the location of the well is excited by pumping the injected fluid together with proppant into the fracture system, This method comprises the steps of: obtaining data on the location of the well containing parameters of natural fractures, and obtaining a mechanical model of the geological environment for I underground formation; form a picture of the growth of hydraulic fractures for a system of cracks over time, while the formation contains: the propagation of hydraulic fractures from the borehole and into the fracture system of the underground reservoir to form a hydraulic fracture system containing natural fractures and hydraulic fractures; determination of parameters of hydraulic fractures after propagation; determination of transfer parameters for proppant passing through a hydraulic fracture system leaf gap; determination of the size of hydraulic fractures based on certain parameters of hydraulic fractures, certain transfer parameters and a mechanical model of the geological environment; and performing voltage shading relative to hydraulic fractures in order to determine the mutual influence of stresses between hydraulic fractures; and repeat education on the basis of a certain mutual influence of stresses. 2. The method of claim 1, further comprising, if the cracks are hydraulic
