摘要: 开发"检测法"油气微生物探测技术并与商业化的"培养法"技术对比发现,检测法具有经济、快捷和易于工业化优势。进而利用其在苏北盆地复杂水网地带开展已知开发油气田样品采集、测试分析和结果评价,与所谓鸡肋型构造采样测试结果对比,发现在检测法未开发区存在多处来自热成甲烷的异常,而在所谓鸡肋型构造区域获得的异常比在已开发油田区的异常高出10倍以上,表明培养法非鸡肋,具有勘探价值。结果表明,"检测法"油气微生物探测技术作为本土开发和理念先进的技术体系,具有重要的深层次应用开发潜力,可为今后取得新的油气田发现做出贡献。Abstract: The application of oil and gas microbial detection technology in the complex water net area, such as the Beihanzhuang Oilfield of the Subei Basin, has shown great advantages to the commercial culturing technology system. As a case study, we selected an oil developing area and an unknown area, where no oil shows have been found, for sample collection, analysis and evaluation. Methane anomalies are found in the oil developing area covered by the complex water net and the proxies in the unknown area without oil discovery are ten times higher than those in the oil developing area. It leads to the conclusion that the area without discoveries so far is not valueless, but has great potential for oil and gas accumulation. It also indicates that the microbial oil and gas detection technology is applicable and should be promoted in the studied region.
