Abstract
The application discloses a kind of clastic rock fracture sweet spot identification method, device and equipment, the method comprises: based on the physical property parameters and geometric parameters of fracture, associated fracture zone and fracture zone in study area, construct the fracture system model of study area;With the fracture data obtained by seismic data interpretation in study area and / or part of fracture system model not constructed fracture data as constraint condition, the fracture system model is interpreted, to obtain the fracture system three-dimensional space data of study area;Based on the corresponding seismic attribute of stratum in study area, and the quantitative identification chart of pre-constructed rock physics-log data, determine the distribution area of clastic rock effective reservoir in study area;Based on fracture system three-dimensional space data and the distribution area of clastic rock effective reservoir, the development area of clastic rock fracture sweet spot is identified.The method greatly improves work efficiency and clastic rock fracture sweet spot identification precision, and has practical guiding significance for clastic rock fracture sweet spot exploration.
