台北凹陷东部浅层油气勘探潜力分析

THE ANALYSIS OF OIL AND GAS EXPLORATION POTENTIAL IN THE SHALLOW STRATUMS OF EAST TAIBEI DEPRESSION

台北凹陷东部油气资源丰富,是吐哈盆地最重要的含油气单元之一。分析认为,台北凹陷东部中侏罗统以上的浅层油气显示活跃、油源充足、储盖组合发育、油气成藏条件极为优越。鄯勒构造带、鄯善弧形带发育众多浅层圈闭,勒11井在Esh试油已获商业气流,预示着东部地区浅层具备良好的油气勘探潜力,是吐哈盆地增加油气地质储量的现实领域。

The Taibei depression is an important oil bearing block in Tuha basin with rich hydrocarbon resources. It is concluded that the shallow stratums above the mid-Jurassic interval in east Taibei depression has great exploration potential, with abundant source rock, developed reservoir-seal assemblage and favorable conditions for reservoir creation. Many shallow traps have been discovered in Shanle and Shanshan structural belt, and commercial gas flow has been obtained in Well L11 in the Teriary strata. All these facts show that the shallow intervals in east Tuha basin have great exploration potential and are promising region to ircrease geologic reserve.
