摘要 七里村油田的主力油层为长6油层,目前对长6储层的地质特征以及油藏特征都取得了一定的认识。近年来,我们发现了七里村油田长4+5油层,但对其还缺乏一定认识,本文对七里村油田长4+5的沉积微相进行研究,从而为其开发提供一定的理论依据[1]。本文对长4+5储层地质特征及影响因素进行分析并取得了以下认识:研究区岩石类型以细砂岩为主,属于中、低孔、低渗储层;机械压实、溶蚀等成岩作用是影响其储层物性的主要因素。 Main reservoir in Qilicun oilfield is Chang6 oil layer; certain understanding of geological characteristics and reservoir characteristics of Chang6 reservoir has been achieved. In recent years, Chang 4+5 oil layers in Qilicun oilfield was found, but it was still not understood. In this paper, Chang 4 + 5 reservoir sedimentary microfacies was studied to provide a theoretical basis for its development. Geological characteristics and influencing factors of Chang 4 + 5 reservoir were analyzed. The results show that: rock types in the study area siltstone, it belongs to middle and low porosity and low permeability reservoir; mechanical compaction, erosion and other diagenesis are main factors affecting reservoir properties.
