| Abstract: | This paper deals with the development and distribution of crack system of carbonate rocks ofYangxin Series Permian in Dazu area, Sichuan Basin by using the methods of geology combining withgeophysics. Firstly, petrology of formation of crack system and reservoir characteristics are studied.Secondly, zones of developed crack system are considered. Thirdly, it is discussed in detail that how thegas-bearing crack system of Yangxin Series can be distinguished from seismic reflection data informa-tion. combining geologic data with seismic data, the writers analyze the rules of developoment and dis-tribution of crack system, and suggest the locations of wells for prospecting drilling. |
