岩石的低孔隙度低渗透率是中国油田都面临的问题,也是油田开发突破的重点,笔者从专业的角度分析了中国油田的低孔低渗的地质成因,主要是由物源和沉积环境、成岩作用、构造作用的影响。并且通过对鄂尔多斯盆地代表性地区储集层的分析,提出了评价方法。
The low permeability and low porosity of rock are the problems that Chinese oilfields are facing and also the breakthrough of oilfield development. From a professional perspective, the author analyzes the geological causes of low porosity and permeability in Chinese oilfields, mainly from the provenance and sedimentary environment, Diagenesis, tectonic effect. And through the analysis of representative reservoirs in the Ordos Basin, the paper puts forward the evaluation method.
