| 摘 要： | 地层水水化学性质与油气成藏具有重要关系，在东营凹陷地层水水化学数据及地质资料分析基础上，明确其古近系地层水水化学具明显的平面分区性及垂向分带性。地层水水化学变化除受原始沉积环境及气候影响外，还受到后期压实排水、外来流体及断裂活动等因素的制约，同时成岩过程中矿物转化脱水和耗水对其也有重要的影响。

| Abstract: | There is an important relationship between the hydrochemical features of local water and oil accumulation. On the basis of the analysis of local water hydrochemical features and geological data of Dongying Sag, the planar division and vertical zonation of paleogene local water was revealed. The local water hydrochemical feature is controlled by later compaction and drainage, foreign fluid and fault activity except the primary sedimentary environment and climate condition. The dehydration and consumption of water because of mineralogic changing during diagenetic process are also important influencing factors. |
