中文摘要:通化盆地是发育在中生代基底之上的断陷盆地,勘探程度低,在该盆地三棵榆树凹陷钻探的通地1井发现油气显示,但油气来源尚不清楚,制约着盆地后续油气资源勘探部署工作。本文通过对通地1井原油和岩心烃源岩生物标志化合物的特征分析对比,发现通地1井原油与下白垩统下桦皮甸子组和亨通山组黑色泥质烃源岩具有类似的生物标志化合物分布特征,推测三棵榆树凹陷原油主要来自下白垩统下桦皮甸子组烃源岩,也可能来自亨通山组烃源岩,这一成果扩展了通化盆地及周缘油气勘探领域,为通化盆地下一步油气基础地质研究和勘探部署提供重要依据。

A STUDY ON THE OIL AND GAS SOURCE OF TONGHUA BASIN, EAST PERIPHERAL BASIN OF SONGLIAO:NWE EVIDENCE FROM TONGDI WELL 1
Abstract:Tonghua basin is a faulted basin developed on the Mesozoic basement with a relatively low exploration degree. Oil and gas was found in Tongdi well 1 in the Sankeyushu sag of Tonghua basin, however, the source of the oil and gas is not clear, which restricts the exploration and development of oil and gas resources in Tonghua basin and its peripheral basins. Based on the comparative analysis on the features of the crude oil in Tongdi well 1 and the biomarker of the core hydrocarbon source rock, it is found that the biomarker distribution features are similar between the crude oil in Tongdi well 1 and black muddy hydrocarbon source rocks of the lower Cretaceous Xiahuapidianzi formation and Hengtongshan formation. It is drawn the conclusion that the crude oil in the Sankeyushu sag is basically from the hydrocarbon source rocks of low Cretaceous Xiahuapidianzi or Hengtongshan formation. This finding broaden the oil and gas exploration filed in Tonghua basin and its surrounding basins, which also provides a great basis for the further study of the basic geological research and exploration of oil and gas in Tonghua basin.
