| Zusammenfassung: | The invention discloses a method and a system for measuring geometric parameters of fracturing fracture.The method for measuring the geometric parameters of the fracturing fracture.The method for measuring the geometric parameters of the fracturing fracture.The method for measuring the geometric parameters of the fracturing fracturecomprises the following steps: establishing a fracturing-containing stratum model by using a three-dimensional finite element method, and longitudinally arranging a multi-component induction logging coil system at a borehole in the fracturing-containing stratum model, constructing an induced electric field calculation model; calculating measurement signal values of coil systems in different receiving directions in the multi-component induction logging coil system when geometric parameters of the fracturing crack are measured; determining a coil system sensitive to geometric parameters of the fracturing crack; the geometric parameters of the to-be-measured fracturing crack are measu |
