摘要

The geological condition of hydrocarbon accumulation in Upper Triassic Xujiahe Formation of Western Sichuan depression is very complicated. The gas reservoir has characteristics of super-deep, super low porosity and permeability, super high pressure, super tight, and so on. Seismic exploration in Xujiahe Formation faces three difficulties, that is, effective prediction of reservoirs, fracture prediction and gas-bearing detection. Recently, wide-azimuthal, large offset and three-component three-dimensional seismic data are the main measures, and deep researches have been made on the characteristics of the multi-wave attribution seismic response of the gas-bearing formation.
