利用三维地震资料分析胜北构造带构造演化与油气聚集

在三维地震资料解释的基础上利用时间厚度法，详细分析了吐哈盆地台北凹陷胜北构造带主要目的层三间房组在燕山中，晚期及喜马拉雅期的构造演化特征，认为胜北２号构造是燕山期古构造，且在喜马拉雅期继承性发育。

Analysis of structural evolution and hydrocarbon accumulation in Shengbei Structural Zone using 3-D seismic data

Based on the interpretation of 3-D seismic data from the Shengbei Structural Zone,Taibei Depression, Tuba Basin, the authors employ the time-thickness method to analyze thestructural evolution of the main target Sanjianfang Formation in the Yenshan and Himalaya Age.It is thought that the Shengbei-2 structure is a paleostructure of Yenshan Age, developinginheritedly in Himalaya Age. Its structural development is well matched with the hydrocarbongeneration and drainage peak of the Shengbei source rocks. Spatially, the Shengbei-2 structure liesat the high position of the slope of oil-generating depression, which is a predominant direction ofhydrocarbon migration. It has a beneficial condition of forming reservoir in two ages andpreserving hydrocarbon. The Shengbei-3 structure is formed in the early Himalaya Age, locatingin the uplift area within depression. Its reservoir-forming time is during the Himalaya Age.
