摘　　要：通过对国外微生物技术在页岩油气开发中的研究与应用进行调研,详细介绍了页岩油气藏内源微生物解堵技术、页岩地层地下DNA诊断技术的原理、工艺、应用情况,以及微生物提高页岩油气采收率、微生物改造页岩储层岩石等的原理和研究进展。研究表明,页岩油气藏中存在微生物,基于油藏微生物对大分子有机物的降解和对油藏特定微生物DNA的检测分析建立的页岩油气藏内源微生物解堵技术、页岩地层地下DNA诊断技术已经进入现场应用,并在提高页岩油气产能和高效储层描述方面取得良好效果。基于油藏微生物对原油渗流能力和储层岩石性质的改善而开展的微生物提高页岩油气采收率研究和微生物改造页岩储层岩石研究都展现了非常好的应用前景。中国页岩油气开发目前处于快速增长阶段,需要借鉴国外经验,探索符合中国页岩油气特色的微生物开发技术。By investigating the research and application of microbial technology in shale oil and gas reservoir development in other countries,the principle,technology,and application of plugging removal technology by indigenous microorganisms in shale oil and gas reservoirs and DNA sequencing diagnosis technology in shale formation are introduced in detail.At the same time,the principle and research progress of enhanced shale oil and gas recovery and transformation of shale reservoir rock by microorganisms are analyzed.The results show that there are microorganisms in shale oil and gas reservoirs.Based on the degradation of macromolecular organic matter by reservoir microorganisms and the detection and analysis of specific microorganism DNA in reservoirs,the plugging removal technology by indigenous microorganisms in shale oil and gas reservoirs and DNA sequencing diagnosis technology in shale formation have been applied in the field,and excellent results have been obtained in improving shale oil and gas productivity and high-efficiency reservoir description.Based on the improvement of crude oil flow ability by microorganisms in reservoirs and that of reservoir rock properties,studies on enhanced shale oil and gas recovery and transformation of shale reservoir rock by microorganisms have shown a very good application prospect.At present,the development of shale oil and gas reservoirs in China is in the stage of rapid growth,so it is necessary to learn from the experience of foreign countries and explore microbial development technology in accordance with the characteristics of shale oil and gas in China.
