为21世纪开拓南方油气勘探新领域

SOUTH CHINA’S PETROLEUM EXPLORATION(8):OPENING UP A NEW FIELD OF PETROLEUM EXPLORATION FOR THE 21’ST CENTURY

根据石油地质学新进展,结合我国南方古生代海相碳酸盐岩发育区的地质特点,提出了促进本区油气地质综合研究的若干设想和建议。认为,应以板块构造理论、现代地层学、盆地模拟、含油气系统及流体封存箱等新概念、新技术、新思路为指导,结合传统技术方法,在区域性研究查明古洋壳型及古过渡壳型盆地的基础上,选择含油气远景较大的盆地,从较高的起点,对其深大断裂带或基底断裂活跃区、不调谐构造、生烃层系的有机质成熟度、油气成藏模型及其分布规律等加以逐一研究,以便为21世纪准备油气勘探新领域。

Based on the regional geologic characteristics of Paleozoic marine carbonate rocks in south- ern China,some envisagements and suggestions have been put forward to improve the comprehensive re- search of petroleum geology in the region.It is suggested that the research should be done involving the new technology,new concepts and new thoughts of the plate tectonics,contemporary stratigraphy,basin analogue,petroliferous system,fluid compartments and so on in combination with conventional technology and methods,to make certain where the ancient oceanic crust and transitional crust exist,and then select more prospective basins.From a higher starting point,researches may be put one by one on great deep- fracture zones or active basement fracture zones,disharmonious structures,organic matter maturity of source rocks,the models of reservoir formation,distribution regularity of hydrocarbon,types and distri- bution of source-reservoir-cap assemblages.
