| 摘 要： | 用主频计算法对长庆气田主力储层中下奥陶统马家沟组马五1段碳酸盐岩的自然伽玛测井曲线进行了分析，得出其主要沉积旋回周期为100、57、36和26ka，基本与米兰科维奇旋回的地球自转偏心率和地轴倾角变化周期相一致，因崦，可以认为储层的沉积旋回是地球自转偏心率和地轴倾角变化引起气候周期性变化形成的，其中又以偏心率影响最大，表明主频计算法用于测井曲线进行分辩率较高的沉积旋回分析是可行的。

| Abstract: | This paper uses the main frequency arithmetic method to analyze the natural gamma logging curves of M 1 5,from Majiagou formation in Ordovician,the main reservoir of Changqing Gas Field,inferring that the main sedimentary cycles are 100,57, 36 and 26 ka,corresponding with the eccentricity cycle and the tilting cycle of Milanlovitch cycle.It is,therefore,reasonable to deduce that the reservoir cycle is controlled by climatic cycle,which is caused by the eccentricity cycle and the tilting cycle,showing that main frequency analysis is feasible to study the high-frequency sedimentary cycle with logging. |
