Abstract
Shale gas "sweet spot" usually refers to an area that contains high total organic carbon content (TOC) and has high brittleness, relatively developed fractures and thick favorable shale, high core pressure. High TOC ensures a high gas content of shale gas, and high brittleness and fracture development guarantees that an effective stimulated reservoir volume (ESRV) can form after fracturing, thus achieving fracture network communication. In this paper,we using seismict attribute to identify shale sweet spot.By elastic parameters crossplots analysis,we established the relationship between the TOC, brittleness and elastic parameters, and extrapolated to a three-dimensional block, we can getting the brittleness and TOC distribution.we can defined different sweet spots by how much the content of TOC&brittleness& pore pressuer.finally,we jointed all parameters by seismic attributes fuse method to identify shale sweet spot.
