| 摘 要： | 将微生物勘探技术应用于大庆卫星油田油气成熟开发区,揭示了卫星油田工区内受断层控制的油气富集规律,将成熟开发区向西侧进行了拓展,且在未知区域发现了4个油气富集区。这4个油气富集区的总面积为16.08km2,占总研究区面积的19.7%,这表明研究区内的含油气远景不是十分理想。根据微生物异常区形态和面积、微生物异常最大值和平均值,将微生物异常区与断层的关系与已知含油气区进行了比较,对4个油气富集区进行了分级。其中:中部异常区为最有利的目标区块;其次是东南异常区。根据卫星油田油气微生物勘探结果,在工区内部署了10口评价控制井。钻井证实,其含油气性符合率达80%。这对于我国的复杂油气藏,特别是岩性油气藏的后期开发提供了一个新的技术支撑,将对我国的油气勘探尤其是在油田开发区寻找剩余油及扩边增储产生深远的影响。

| Abstract: | The microbial prospecting for oil and gas (MPOG) technology was applied to the mature development area in Satellite Oil-field of Daqing area. The accumulation regularity of hydrocarbon controlled by faults was interpreted with the MPOG technology. The mature development area was extended out to the western part in the studied area, and four favorable hydrocarbon accumulation zones were discovered in the unknown district. The total area of the four zones is 16.08 km2 and about 19.7% of the total studied area, which displays that those zones are unsatisfied in oil and gas potential. Based on the main shape and area of microbial abnormity zone and microbial abnormity maximum and even values, the relationship between microbial abnormity zone and faults was compared with that of the known developed zone in the studied area. The four favorable hydrocarbon accumulation zones were classified. Among them, the middle abnormal zone is the most favorable target for oil and gas exploration, and the southeast abnormal zone is better one. According to the results of MPOG, ten evaluation-controlling wells were planned and drilled in the studied area. The MPOG results were verified by the hydrocarbon-bearing conditions of the drilled 10 wells. The consistent rate of hydrocarbon-bearing is up to 80%. This technology can provide a new technical support for complicated reservoirs, especially for the late development of litho-reservoirs in China. |
