| 摘 要： | 甘谷驿油田北部长6储层主要为细粒长石砂岩为主，次为粉细砂岩。通过对该区40余口探井的钻井、录井、测井以及化验分析资料，对研究区的沉积相以及其与油气的关系展开了研究。研究发现，该区长6砂体主要为湖泊三角洲沉积体，发育三角洲前缘与前三角洲亚相及多种微相类型。其中水下分流河道和河口坝砂体对油气的聚集起着主导作用。

| Abstract: | The oil - bearing strata in North of the Ganguyi Oilfield is mainly the fine grained Arcose, next is silt-fine sandstone. According to the analysis of well drilling, well logging, testing data of more than 40 of wells, research of sedimentary facies in this area and its relationship with petroleum accumulation and distribution have been completed, it can be concluded that the sand bodies of the Chang 6 oil-bearing unit are mainly lacustrine delta deposits, including delta plain and delta front. Microfacies of distributary channel and mouth bar are dominant factors for Petroleum accumulation of this area. |
