摘　　要：鄂尔多斯盆地长4+5油组是长庆油田近年来油气勘探发现的新的含油气储层,目前主要勘探重点集中于盆地内姬塬地区。该区长4+5组油气储层孔渗性极差,为超低渗储层。应用铸体薄片、扫描电镜、阴极发光、X-衍射等分析手段,研究了长4+5组超低透储层的各种成岩现象,确定了储层的成岩阶段,划分了储层成岩相,探讨了储层成岩作用对孔隙演化的控制和影响性,指出了有利的储层成岩相及对含油气性的影响。因此本次研究对长庆油田超低渗透油气藏勘探有积极的指导作用。Ordos Basin oil group Chang 4 ＋5 Changqing Oilfield discovered in recent years,new oil and gas exploration oil and gas reservoirs,currently the main exploration focus on the basin Jiyuan area.The District 4＋5 group of oil and gas poor reservoir porosity and permeability,ultra-low permeability reservoir.Thin casting,scanning electron microscopy,cathodoluminescence,X-diffraction and other analytical tools to study the long 4＋5 group of ultra-low permeability reservoir diagenetic phenomena,to determine the reservoir diagenesis,diagenetic reservoir divided phase of the reservoir diagenesis on porosity evolution of control and influence of that favorable diagenetic reservoir facies and hydrocarbon potential impact on,so study to ultra-low penetration of Changqing Oil Field oil and gas exploration has a positive guidance.
