摘　　要：在总结大庆油田西部地区姚一段石油地质条件的基础上,采用油气成藏动力学研究方法,利用盆模技术模拟了盆地的演化过程和烃源岩生、排烃史,恢复了明水期末—依安期初烃源岩的供烃量和姚一段顶面油气运移的动力条件;根据对各类输导通道的分析,建立起该时期以砂岩输导层为主的输导格架。采用以逾渗理论为基础的油气运聚模拟方法,对供烃量、运移动力和输导格架进行了耦合分析,获取了姚一段油气运移路径的特征、分布及运移量。再结合其他油气成藏的控制因素,预测敖南鼻状构造、大安鼻状构造、英台鼻状构造、他拉哈地区及巴彦查干北部的低幅度构造为有利的勘探远景目标区。The petroleum geological conditions of the first member of Yaojia Formation in the west of Daqing Oilfield were analyzed.The evolution history of the basin and the hydrocarbon generation-expulsion history of source rocks were simulated,and the dynamic conditions for hydrocarbon migration were successfully reconstructed using the basin modeling techniques.The characteristics of sandstone,unconformity and faults carriers were investigated,and a hydrocarbon carrier framework model was constructed.The coupling analysis on migration dynamics and pathways was made using the hydrocarbon migration and accumulation modeling methods as well as the percolation theory.The distribution of hydrocarbon pathways,migration directions and migration quantity of the first member of Yaojia Formation in Daqing Oilfield were obtained.Those study results combined with other petroleum geological conditions were used to prospect the target zones.Some favorable exploration zones such as Aonan nose structure,Da＇an nose structure,Yingtai nose structure,Tahala area and the structure in the north of Bayanchagan were identified.
