摘　　要：在松辽盆地西部杜75块应用油气微生物勘探,结合区域沉积相分析,对研究区进行了分流河道砂体、河口砂坝以及远砂坝等有利储集砂体的预测。根据油气微生物异常分布特征,明确了研究区的油气富集规律,即油气基本上分布于构造较宽缓的平台区域,或是具有微幅鼻状构造处,或是在水下分流河道分流处,为现场勘探提供了可靠的决策依据。同时,对研究区乃至整个松辽盆地西斜坡的岩性油气藏勘探奠定了基础。Microbial prospecting has been applied along with regional sedimentary facies analysis to the Block Du75 in western Songliao Basin for prediction of favorable reservoir sand bodies such as distributary channel,mouth bar and distal bar.The distribution features of microbial anomaly represent hydrocarbon enrichment pattern in the study area,i.e.oil and gas mostly occur in gentle flat structures or slight nose structures or the shunting place of distributary channel.The study results have provided reliable basis for decision making in field exploration and laid a foundation for the exploration of lithologic reservoirs in the study area and the entire western slope of Songliao Basin.
