苏干湖盆地连续电磁剖面和微生物基因定量油气勘探
降低勘探成本、提高勘探成功率,是油气行业发展之趋,其中物化探手段尤为关键。联合应用连续电磁剖面法和微生物基因定量技术,在研究程度较低的苏干湖盆地油气勘查得到积极发现：（1）盆地＂四凹五凸＂构造特征具备形成油气藏的储盖条件及运移通道,东部山前二叠、石炭系凹陷,中、西部侏罗系凹陷可能为烃源区;（2）相对钻孔揭示有油气显示的盆地中部凹陷,东部山前凹陷周缘和西部凹陷周缘,油气指示菌基因含量增大,可达1数量级,预示该两区油气更富集;（3）综合判断：东部山前二叠、石炭系凹陷,西部侏罗系凹陷,可能存在可开采油气藏。物化探方法联用对隐蔽性油气藏勘探有重要意义。...

| Bibliography: | How to reduce costs and improve success rate of exploration is one of the focused issues in oil and gas industry. To solve this problem,application of geophysical and geochemical methods is crucial. Using continuous electromagnetic profiling and quantitative detection of gene technique,an oil and gas exploration was conducted in the Sugan Lake basin with few available data. The results show that the structure of＂four uplifts and five depressions＂of Sugan Lake basin has reservoir conditions and migration pathways for generation of hydrocarbon reservoirs. The Sinian and Paleozoic depressions of the eastern piedmont,and Jurassic depressions of the central and western basin may be source areas. The content of genes indicating potential oil and gas in the edges of the eastern piedmont and western depressions is larger by one magnitude of order than that in the central depression where drilling logs reveal oil and gas,predicating these areas are more likely the localities with oil and gas accumulation.
