| 摘 要： | 在对录井、测井、分析测试等资料综合分析的基础上，结合模拟实验对博兴油田沙四上亚段滩坝砂岩储层非均质性特征及其对油气成藏的影响进行了分析。结果表明:研究区滩坝相储层主要为砂泥薄互层状分布，储层非均质性强；油气分布呈严重不均一性，不同井区、不同砂组含油特征迥异；成岩作用导致该区储层质量差异较大，储层质量与含油气性有较好的正相关性，空间储层非均质性控制了油气充满度及宏观分布特征。模拟实验显示，成藏动力和成藏阻力的配置关系会影响油气的富集特征，并在一定程度上弱化储层非均质性对油气成藏带来的影响。

| Abstract: | Based on the analyses of logging data and experiment, it is discussed in this paper the reservoir bed heterogeneity and its effects on hydrocarbon accumulation in the upper fourth member of Eocene Shahejie Formation of the Boxing oilfield. The result shows that the beach-bar reservoir bed with thin interbedded sandstone has strong heterogeneity. Hydrocarbon distribution and property are extremely uneven. Influenced by diagenesis, beach-bar sandstone shows strong heterogeneity, leading to different reservoir bed qualities in different areas. Reservoir bed quality has a good correspondence with hydrocarbon-bearing property, and reservoir bed heterogeneity controls the accumulation and distribution of hydrocarbon as well as oil saturation. Simulated experiment indicates that the relationship between driving force and resistance has effects on hydrocarbon accumulation feature and weakens the control of hydrocarbon accumulation by reservoir bed heterogeneity to a specific extent. |
