霸县凹陷是冀中拗陷生油凹陷之一。本文用微量元素对比的方法,对凹陷中各层分布特征、油气运移、油源对比等问题进行探讨。首先选用71口井75个原油样品、48口井水样和29口井60个生油岩岩样,用发射光谱测定了V、Ni、Fe、Mn、Cu、Zn、Cr、Ba、B、Ga、Pb、Al、Ti、Zr、Mo、Co等微量元素的含量。引用原有的75个原油样品物性数据和8口井300个岩石样品微量元素数据。1。元素在不同层位中的分布及在分层中的应用(1)不同层位原油中微量元素分布特征。Ni、V、Ga、Pb在第三系原油中的含量大体
Baxian depression is one of the oil-producing sags in the Jizhong depression. In this paper, the micro-element contrast method, the depression in the distribution characteristics of each layer, hydrocarbon migration, oil source contrast and other issues are discussed. First of all, 75 crude oil samples of 71 wells, 48 wells of water samples and 60 raw oil rock samples of 29 wells were selected. The emission spectra were used to determine the contents of V, Ni, Fe, Mn, Cu, Zn, Cr, Ba, Ga, Pb, Al, Ti, Zr, Mo, Co and other trace elements. The original data of 75 crude oil samples and the trace data of 300 rock samples from 8 wells were quoted. 1. Distribution of elements in different horizon and its application in stratification (1) Distribution of trace elements in crude oil of different horizon. The content of Ni, V, Ga, Pb in Tertiary crude oil is roughly
