利用“四性”关系识别建南构造东岳庙段页岩气储层

建南构造侏罗系下统自流井组东岳庙段泥页岩发育,邻井多口井在该段普遍见良好的油气显示。页岩气储层为自生自储型油气藏,属于泥岩性质储层,具有低孔隙、超低渗透率的特点。对建南构造自流井组东岳庙段页岩气储层岩性、物性、电性、含气性特征及储层"四性"关系的研究,结合岩心、气测录井、试气等资料统计分析出页岩气储层的物性和电性下限值,进一步建立有效厚度解释图版,可定量得出页岩气层的解释下限标准。

On Distinguishing Shale Gas Reservoir of Dongyue Temple Section by Means of "Four Properties" Relations

Mud shale distributing in Ziliujing Formation Dongyue Temple Section of lower Jurassic system with Jiannan structure grows well and many adjacent wells display oil and gas.Shale gas reservoir is auto-generation and auto-storage type which belongs to mudstone-based reservoir with the characteristics of low porosity and low permeability.The minimum standard for interpreting shale gas reservoir can be obtained quantitatively with the help of research on "four properties"(rock property,physical property,electrical property and gas-bearing property)of shale gas reservoir in the section and their relations,analysis of the minimum value of its physical and electrical properties combined with the data of rock core,gas-logging and gas testing and further building the plate to interpret effective thickness.
