| 摘 要： | 利用测井资料对比分析了阿雷斯油田和南阿雷斯构造的地层特点，并确定了4 个标志层，认为白垩系和上侏罗统的阿克萨布拉克组的地层分布比较稳定，层内小层地质特征可对比性高，该组与下伏侏罗统地层为不整合接触关系; 库姆科尔组应为中下侏罗统残余地层。详细分析了其南侧的南阿雷斯构造相应层位之间的地层关系，认为阿克萨布拉克组与库姆科尔组之间不整合特征明显，阿雷斯油田的阿克萨布拉克组与其下伏侏罗系地层存在不整合关系。基于上述不整合地层关系的认识，认为阿雷斯油田中下侏罗统油藏类型为多个地层不整合油藏。目前钻遇基底的出油井为单独成藏，受古隆起控制。

| Abstract: | Analyzing the stratigraphic characteristics of the Arys oilfield and South Arys structure,the authors identified four marker beds based on the logging data,and considered that the Akshabluk Formation was distributed in a relatively stable conditions in Cretaceous and Late Jurassic,which was used detailed comparison of geological characteristics in sublayers level.Meanwhile,the authors considered that the Akshabluk Formation was unconformable with its underlying Kumker Formation,which should be the residual formation of Middle-Lower Jurassic.Moreover,the authors analyzed the stratigraphic relation of the corresponding layers of the South Arys structure,which showed that the unconformity was existed between the Akshabluk Formation and Kumker Formation,indicating the fact of unconformity between the Akshabluk Formation and its underlying Jurassic strata in Arys oilfield.On the basis of the recognition of unconformable relationship,the reservoirs of the Arys oilfield in Lower Jurassic were the multiple stratigraphic unconformity reservoirs in type.Present oil wells of the basement were independent reservoirs controlled by paleo-uplift. |
