Abstract: Pingqiao shale gas field in Fuling area,located in the fault anticline of Fenglai Syncline,has a narrow-abrupt slope belt.The proved geological reserves are 1 389.17×108m in the Wufeng-Longmaxi Formations,suggesting Pingqiao shale gas field possesses good potential for shale gas exploration.In order to study the features,major factors controlling the accumulation and high productivity and the reasons for production variance from different wells in Pingqiao shale gas field,the article makes a detail analyses of Pingqiao shale gas field based on drilling,logging,seismic and experimental data.The results show that:(1)The  thickness of Pingqiao shale gas layer(TOC≥1%) is 115-155m;the thickness of quality layer(TOC≥3%)at the bottom is 36-40m,the shale gas is featured by high reserves(reserve abundance 12.68×108m3/km2),high pressure of shale gas accumulation(pressure ratio 1.56),high production of wells(average testing production 21.99×104m3/d).(2)Deep shelf quality shales and the faults showing weak slipping,good sealing and no pressure-leaking area are found in surrounding area,being the main controlling factor to shale gas accumulating and high production in Pingqiao shale gas field.(3)Micro-fractures,structural location and depth are also key factors for various productions of wells in Pingqiao shale gas field under the similar accumulating circumstances.


Key words: Pingqiao shale gas field, Wufeng-Longmaxi Formations, Narrow-slip faulted anticline, Preserving conditions, Main controlling factors of shale gas accumulation
