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(O_(2-3)—D_2);其上沉积了晚古生代(D_3—P_1)碰撞前陆型的海相、海陆交替相和陆相沉积及古生代末—新生代(P_2—Q_1)多期发展的碰撞山前陆相沉积,从而形成了多套油气源,并具备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。
Santanghu Basin is of oil and gas prospect. The authur discussed the evolution, type and oil-bearing possibilityof the basin, based the analysis of the geological and geophysical data collected during the past 30 years. The base-ment of the basin is a trench-arc-basin marginal marine sediment system on the frontal active continental margin ofthe Siberia antient land. The metamorphic basement(O_(2-3)-D_2) was formed by folding movement and igneous intru-sion of the system in later period. On the basement deposited the late Palaeozoic(D_3-P_1)collision foreland marine,paralic and continental sediment,and the late Palaeozoic - Cainozoic (P_2-Q)multi-stage collision piedmont conti-nental sediment. Therefore several hydrocarbon sources were formed. The basin has the geotectonic condition forforming non-biogenic sources. It is a medium-scale basin with relatively rich oil and gas resource. Recomendationsconcerning the oil and gas prospecting in the basin are proposed.
