| 摘 要： | 以鄂尔多斯盆地ZH40区块水下浊积扇沉积体系为例,根据储层物性、铸体薄片鉴定、扫描电镜和X-衍射分析等资料,定量研究水下浊积扇沉积体系沉积微相对物性和成岩的控制作用。分析表明:从水下扇的扇根到扇中,再到扇缘,矿物成分成熟度呈先增加后降低的趋势,扇中微相的长石砂岩最为发育,成分成熟度和结构成熟度最好;在水下扇浊积体系中,扇中微相砂体的溶蚀作用和次生孔隙最为发育;扇根、扇中和扇缘微相砂体机械压实作用引起的孔隙度损失程度接近,而扇根和扇缘微相砂体的胶结作用强烈。储集层成岩作用研究和孔隙度预测中,必须考虑沉积微相的控制作用。 |

| Abstract: | The controls of the sedimentary microfacies of turbidite fan on the physical property and diagenesis in the Zhuang 40 area of Xifeng Oil Field are discussed quantitatively based on porosity data,thin sections,blue epoxy resin-impregnated thin sections,SEM,and XRD data.The results show that mineral maturity of sandstones increases from the inner to middle fan,and decreases from the middle fan to fan front.Both mineral and textural maturities of the medium fan sandstones are higher than the neighboring microf... |
