复电阻率测井评价富有机质页岩储层的理论研究

Theoretical study of complex resistivity well logging evaluation on organic-rich shale reservoirs

复电阻率测井相对于常规测井在评价水淹层,识别油水层有其独特的优势。页岩复电阻率在低频阶段表现出强激发极化效应,这与其优质页岩储集层中含有黄铁矿以及沉积环境等有关。

The complex resistivity logging has advantage in water flooded layer evaluation and water layer identification thanconventional technologies.The complex resistivity of shale at low frequencies exhibits strong induced polarization effect,whichdepends on its high-quality shale reservoirs layer containing pyrite and sedimentary environment.
