【摘要】：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。
[Abstract]:Reducing exploration cost and increasing exploration success rate are the development trend of oil and gas industry, in which geophysical and geochemical exploration means are particularly critical. In combination with continuous electromagnetic profiling and microorganism gene quantitative technique, it is found that the characteristics of "four concave and five convex" structures in the Sugan Lake basin, which has a low degree of research, have the reservoir cap conditions and migration channels to form oil and gas reservoirs. East Piedmont Permian, Carboniferous Sag, Middle and West Jurassic Sag may be hydrocarbon source area Guan2) the oil and gas display basin central sag, the eastern Piedmont depression periphery and the western depression periphery, the oil and gas indicator bacteria gene content increases, It can reach 1 order of magnitude, which indicates that the oil and gas of the two areas are more enriched than that of Huiguo 3) comprehensive judgment: East Piedmont Permian, Carboniferous sag, West Jurassic sag, there may be recoverable oil and gas reservoirs. The combination of geophysical and geochemical exploration methods is of great significance to the exploration of hidden reservoirs.
