湖南省涟源凹陷泥盆纪佘田桥组页岩储层测井评价

Logging Evaluation of Shale Reservoir in Devonian Shetianqiao Formation in Lianyuan Sag, Hunan Province

湘中地区涟源凹陷泥盆纪佘田桥组(D3s)富有机质页岩发育,区内参数井-湘新页1井(XXY-1)已在该组钻遇良好页岩气。为研究该套储层特征,依托湘新页1井的岩心和测井资料,通过数控测井系统的综合测井曲线响应特征和数据处理结果对该套储层进行了评价。结果表明,湘新页1井泥盆纪佘田桥组底部为优质页岩发育段,厚度达81.1 m,页岩TOC、物性均较好,具有较大资源潜力。

The Devonian Shetianqiao Formation(D3s)in Lianyuan sag,central Hunan Province is rich in or-ganic shale,and has been encountered good shale gas in the parameter well XXY-1.The core and logging data of the XXY-1 well were used to study the shale reservoir characteristics of Devonian Shetianqiao Formation in Lianyuan sag,and the reservoir was evaluated through comprehensive logging curve response and data pro-cessing results of NC logging system.The results show that the bottom of the Devonian Shetianqiao Forma-tion of XXY-1 well is a 81.1 m thick high-quality shale section with high TOC and good physical properties,and has great resource potential.
