摘要： 三塘湖盆地是一个有含油气远景的盆地。本文作者在对该盆地30多年来所累积的地质—地球物理资料进行分析的基础上,探讨了盆地的演化,类型及含油气性。认为盆地的基底属西伯利亚古陆前缘主动型大陆边缘的沟—弧—盆边缘海沉积系统,经后期褶皱运动和岩浆侵入活动形成盆地的变质基底(O2-3-D2)其上沉积了晚古生代(D1-P1)碰撞前陆型的海相,海陆交替相和陆相沉积及古生代末一新生代(P2-Q1)多期发履的碰撞山前陆相沉积,从而形成了多套油气源,并具奋形成非生物成因油气源的大地构造条件,是一个油气资源比较富集的中型盆地。作者并对盆地的油气勘探工作提出了建议。

Abstract: Santanghu Basin is of oil and gas praspeet.The authur discussed the evolutan,type and oil-bearing possibility of the basin,based the analysis of the geoiogical and geophysical data ollected during the past 30 years. The basa-ment of the basin is a trench-arc-basin marginal marine sediment system on the frontal active continental margin of the Siberia antient land. The metamorphic basement (O2-3-D2) was formed by folding movement and igneous intru-slon of the system in later period. On the basement deposited the late Palaeozoic (D1-P1) collision foreland marine, paralic and contincntal scdiment, and the late Palaeozoic—Cainozoic (P2-Q) multi-stage collision piedmont conti-nental sediment. Therefore severai hydrocarbon sources were fomed. The basin has the geotectonic condition for forming non-biogenic sources. It is medium-scale basin with relatively rich oii and gs resource,Recomendatioans concerning the oii and gas prospecting in thc basin are propased.
