摘要
高邮凹陷花庄油田阜三段为低渗、特低渗油藏,综合运用岩心砂岩薄片、铸体薄片、扫描电镜、X-衍射分析等资料,对储层非均质性从层内、层间、平面和微观非均质性进行了分析。研究表明,花庄油田阜三段储集层非均质性较强。分析了非均质性的影响因素,认为其非均质性主要受控于储层的沉积微相及成岩相,埋深对储层非均质性也有一定的影响。
The Fu3 reservoir in the Huazhuang oilfield of the Gaoyou depression features low and extra-low permeability.This paper studies the reservoir heterogeneity in respects of inter-layer,intra-layer,plane and microscopic heterogeneities by integrating data of sandstone core section,cast thin section,scanning electron microscope and X-diffraction analysis.The study shows that the Fu3 reservoir in the Huazhuang oilfield is severely heterogeneous.The influence factors of the reservoir heterogeneity mainly involve sedimentary microfacies and diagenesis,as well as burial depth which also had a certain influence on reservoir heterogeneity.
