摘要

摘要: 对塔里木盆地新和地区油气微生物异常特征进行了研究，为该地区油气预测和油气微生物勘探技术的推广和应用提供依据。主要采用平板培养计数法、16SrRNA基因克隆文库法与高通量测序法对土壤样品中的油气微生物进行定量检测，利用这些方法研究了新和地区油气微生物种群构成及数量异常情况，构建出研究区油气区的油气微生物异常模式。以此为依据，对新和及三道桥地区低幅度圈闭线索区域的油气微生物进行检测，根据油气微生物异常特征预测油气有利区。最终识别出5个微生物异常区，并结合构造圈闭认识结果及油气微生物数量异常，优选出5个潜在的有利勘探目标区。

Abstract: The Microbial Prospecting for Oil and Gas (MPOG) is an exploration method based on the seepage of light gaseous hydrocarbons from oil/gas reservoirs to the surface and their utilization by hydrocarbon oxidizing bacteria. By studying the abnormal characteristics of oil and gas microorganisms in Xinhe area of the Tarim Basin, this project provides a solid scientific basis for oil and gas prediction and the validation and application of oil and gas microbial exploration technology in this area. Soil samples were collected to investigate prospects for hydrocarbon exploration. The amount of cultivable soil microorganisms in different soil samples were analyzed using the agar plating method. High-throughput sequencing has been used directly to study the composition of microbial population in soil samples. Based on the data from Xinhe area, an abnormal pattern of oil and gas microorganisms has been established. By using this pattern, five abnormal microbial areas were identified in the Xinhe and Sandaoqiao area. Combined with the results of structural traps and the abnormal number of hydrocarbon microorganisms, five potential favorable exploration target areas were identified.
