| 摘 要： | 倪丘集凹陷是在中、古生界基础上于早第三纪成生发展起来的陆相沉积小盆地。具有地质结构复杂、断块发育、非均质性强、含油层系多、油气显示活跃、原油多源等特点。有一定油气前景，但勘探难度较大，不适用常规的勘探开发程序。下一步勘探开发应以小型断块油气藏为主要类型，采用多学科综合研究、多因素综合考虑、多手段协同作战的综合勘探方法，在综合评价的基础上优选有利区块，实施滚动勘探与开发。

PETROLEUM GEOLOGICAL CHARACTERISTICS AND KNOWLEDGE OF EXPLORATION THINKING IN THE NIQIUJI SAG |
| |
| Abstract: | The Niqiuji sag was a small coutinental depositional basin of contemporaneous growth in Eogene period on Mesozoic and Palaeozoic formations, which has the characteristics of complex geologic configuration, fault-block development, strong anisotropism, multiple oil measures, frequent showing of oil and gas, multiple oil source,and has certain oil gas exploration prospect, but the exploration are very difficult and the routine exploration and development methods are unsuitable. The next exploration should take the smal fault-block oil-gas accumulation as the dominant, and adopt comprehensive survey by a miscellaneous investigations with multiple subjects, synthetical thinking with multiple factors, fighting in coordination with multiple methods, optimize advantageous target areas and carry out rolling prospecting and development. |
