| 摘 要： | 断裂系统在油气地质及成藏规律研究中具有重要意义。对于勘探和研究程度较低或很低的地区,应拓宽思路,充分利用各个地区的有利条件,开展多样的勘探和研究工作。在充分依靠先进勘探技术的同时,还应重视地面地质调查,尤其是重视已发现的地表油苗价值的开发。江西弋阳盆地和浙江金衢盆地白垩系红色砂质岩层内广泛分布裂缝性含油、含沥青显示说明,其分布明显受区域性断裂系统的控制。断裂系统与孔渗性相对较好的砂质岩配置,可形成地表油苗相对富集。

| Abstract: | Fracture system plays an important role in researching petroleum geology and reservoir formation regularity.As for those areas where the exploration and research are low-level, we should widen thought trains to carry out varieties of exploration and research work with the full aids of favorable conditions in each areas.Advanced exploration technology must be fully utilized,meanwhile much attention should be also paid to surface geological survey,especially to the development significance of discovered surface oil seepages. Fissured oil-bearing and bitumen-bearing showings are widely distributed within Cretaceous red sandy rock strata in Yiyang Basin,Jiangxi province,and Jinqu Basin,Zhejiang province. It is shown that the distribution of these showings is under the control of regional fracture system.Surface oil seepages will be accumulated usually in the places where fracture system is accompanied with well porous and permeable sandy rock. |
