| 摘 要： | 通过对塔里木盆地塔中隆起及其北坡两顺地区志留系油气成藏地质条件分析,认为两顺地区志留系具备形成工业油气藏的条件。志留系油气显示层段储层包裹体的均一化温度和含盐度测定结果显示存在两个成藏期:早期和晚期。早期油藏遭受部分或全部被破坏,其中塔中地区已演化为沥青砂岩,两顺地区破坏程度相对较低;晚期成藏基本未被破坏,既可单独形成新的油气藏,也可对早期(残余)油藏进行再充注。对S1井油气钻井资料综合分析发现,两顺地区早期油气藏并未形成沥青砂岩,而是形成残余油藏并接受了晚期成藏阶段的油气再充注,推测从S1井到满加尔坳陷方向,存在志留系早期原生油气藏的可能性。 |
| 关 键 词： | 两顺地区 志留系成藏 成藏期 早期残余油藏 晚期油气再充注 |

| Abstract: | Based on the analysis of geological conditions of the Silurian oil and gas reservoir in the Liangshun area of Tazhong uplift,Tarim Basin, it is suggested that the Silurian of Liangshun area is of the conditions of forming commercial reservoir. The homogeneous temperature determined by the analysis of inclusions and salinity reveals that there are two accumulation stages, the early and the late stage.During the early stage, the reservoirs is suffered partly or completely destruction,characterized by the formation of asphalt sandstone in the Tazhong area,while Liangshun region is subjected to relatively low level of destruction.The pool accumulation of the late stage is basically undisturbed.It either forms new gas and oil reservoir or refills the early reservoir.Comprehensive analysis of geological data of the Well Shun1 indicates that the early gas and oil accumulation is characterized by residual reservoir,which is refilled by gas and oil during the late stage,instead of the formation of asphalt sandstone. It is likely that there is primary gas and oil reservoir from the well S1 to Manjiar depression. |
| Keywords: | Liangshun region Silurian pool forming oil-forming period early residual pool late oil and gas recharge |
