摘要
Well JY1 is located in the east of Sichuan Basin. According to the analyses of the structure,formation combination,lithology,TOC,RO,and mineral contents,combined with regional geological data,following conclusions have been obtained: 1)structural and preservation conditions are the most important for shale gas to accumulate under the background of multiple structural evolutions and uplifts and erosions; 2)only the qualitative hydrocarbon rocks can play the role of detachment,and net-like fractures by multiple detachments and tectonic movements are key factors for shale gas abundance and high production; 3)the Upper Ordovician limestones take the role of sealing for the abundant shale gas in Longmaxi Formation; and 4)faults and uplifts made a few destructions to shale gas reservoirs.All implications above will have an exemplary meaning for shale gas exploration in southern China.
