    摘要:

    近年来长9优质烃源岩的发现,及相邻的长8、9、10储层中好的油气显示和工业油流的获得,表明长9可能是一套重要的潜在烃源岩。对此本文对鄂尔多斯盆地长9烃源岩生烃潜力进行了定性和定量评价。结果表明,鄂尔多斯盆地长9优质烃源岩主要集中在志丹、英旺地区,计算得出鄂尔多斯盆地长9烃源岩油气资源量分别为(2.09~4.17)?08t和(0.06~0.12)?011m3。由于英旺地区排烃效率较低,资源量主要集中在志丹地区。因此,在志丹地区进行油气勘探时应考虑长9烃源岩的贡献。

    Abstract:

    In recent years, the discovery of Chang 9 Member high-quality hydrocarbon source rocks and the good hydrocarbon show and the gain of commercial oil flow in Chang 8, 9, 10 Reservoir , which indicate Chang 9 Member may be a set of important potential hydrocarbon source rocks. Therefore the hydrocarbon generation potential of hydrocarbon from source rock of Chang 9 Member was researched qualitatively and quantitatively in this paper. The result indicated that the quality source rock of Chang 9 Member, Yanchang Formation, Ordos Basin is mainly distributed in Zhidan and Yingwang areas. Hydrocarbon resources from source rock of Chang 9 Member in Ordos Basin are (2.09~4.17)?08t and (0.06~0.12)?011m3 . Because of the low expulsion efficiency of hydrocarbon in Yingwang area hydrocarbon resources mainly concentrate in Zhidan area. Therefore, hydrocarbon resources from source rock of Chang 9 Member should be considered when oil and gas exploration is conducted in Zhidan area.
