摘要
微生物油气检测技术通过采集地表土壤或海底表层沉积物样品,使用微生物学方法和地球化学方法检测样品中专属微生物的数量和群落结构,预测地下油气藏的存在、分布,具有多解性小、快捷、经济等特点。近年来通过持续研发,微生物现场快速检测技术、环境校正技术等关键技术取得重要进展,提高了技术的预测精度、可靠性和工作效率。新技术在准噶尔盆地深层构造、火山岩、岩性油气藏等多个领域得到应用,成功预测了GT1井、CT1井等多口风险探井的含油气性,为复杂地质和地表条件下的新区含油气性快速评价提供了新的方法和模式,在准噶尔盆地南缘下组合构造、西北缘石炭系火山岩、东部侏罗系和二叠系岩性油气藏勘探中具有广阔的应用前景,但技术的运用应避开基岩出露区、流沙区、轻烃缺失的稠油油藏等区域,在判断油气藏深度和层位方面也存在不足。
Microbial oil and gas detection technology can predict the occurrence and distribution of oil and gas reservoirs,which has the characteristics of less multi-solution,fast and economic.This technology adopts microbiological and geochemical methods to detect the number and community structure of exclusive microorganisms of sediment samples collected from surface soil or seabed.In recent years,key technologies such as the rapid on-site microbial detection and environmental factor correction have made important progress through continuous research and development,improving the prediction accuracy,reliability,and exploration efficiency.It has been applied in many fields in the Junggar Basin,such as deep structure,volcanic rock,and lithologic reservoir,which successfully predicted oil and gas bearing potential of several risk exploration wells,i.e.,Wells GT1 and CT1,providing a new method and model for rapid evaluation of oil and gas bearing potential in new areas with complex geological and surface conditions.Therefore,it has broad application prospects in the exploration of structural reservoirs of lower assemblage in the southern margin,Carboniferous volcanic reservoirs in the northwestern margin,and Jurassic and Permian lithologic reservoirs in eastern margin of the Junggar Basin.However,the application of this technology has deficiency in bedrock exposed area,quicksand area,heavy oil reservoir with lack of light hydrocarbon and other areas,as well as in identifying the depth and horizon of oil and gas reservoirs.
