| 摘 要： | 运用岩心观察、粒度分析、地震及测井曲线形态分析等资料，结合单井相、剖面相分析，对永安镇油田沙三段上亚段一沙二段下亚段沉积特征进行系统研究，确定其发育河流一三角洲相沉积和湖泊相沉积。三角洲相沉积在该地区发育三角洲平原亚相和三角洲前缘亚相。湖泊相发育滑塌沉积。系统研究了储集砂体的时空演化、展布规律及砂体发育的控制因素，分流河道微相和河口坝微相是该区最有利的储集砂体，对下一步石油地质勘探研究具有重要的地质意义。

| Abstract: | This paper deals with sedimentary characteristics of the upper of 3rd Member to the lower of 2nd Member of the Shahejie Formation in the Yonganzhen Oilfield based on core observation, granulometric analysis, seismic and logging data in combination with the facies analysis of single wells and profiles. The results indicate that they belong to river delta and lacustrine facies. The river delta facies may be divided into delta plain and delta front subfacies. Olistostrome was developed in lacustrine facies. The space-time evolution and controlling factors of sandbodies have been systematically studied. The distributary channel and distributary mouth bar microfacies are the best favorable reservoir sands in this area. |
