南华北中区二叠系低孔渗砂岩的成岩作用

Diagenesis of Low Prosity and Permeability Permian System in South Northern China Middle Area

在大量的室内多种观察、测试分析的基础上，按砂岩成岩特征和孔隙演化受控于沉积环境的观点，提出与环境密切相关的岩石微相可直接影响砂岩的成岩作用和孔隙演化，并从成岩相角度，分析研究了区内砂岩的成岩作用和储集性。

Based on lots of indoor observation, tests and analyses, from the viewpoint of that the diagenetic characteristics of sandstone and the development of pore is submitted by the sedimentary envirnoment, this paper prompts that the litho-microfacies Which is closely related to the environment can directedly effect the diagenesis and develoment of pore of Sandstone. And it studies and analyses the diagenesis and reservoirs of sandstone in south Northern China middle area from the angle of facies of diagenesis.
