三维地质模型的建立——以阿尔及利亚Zarzaitine油田为例

ESTABLISHMENT OF THE THREE-DIMENSIONAL GEOLOGIC MODEL:TAKING THE ZARZAITINE OIL FIELD FOR AN EXAMPLE

对阿尔及利亚Zarzaitine油田储层岩芯进行观察与描述,在沉积特征综合分析的基础上,结合岩芯的分析化验资料、测井和区域地质背景资料,根据沉积微相和电相之间的对应关系研究,划分出了各小层沉积微相。从沉积微相的分布特点,分析了该区储层(F4)沉积微相的空间演化规律,进而建立了该油田储层(F4)的三维地质模型。

Based on the multidisciplinary analysis of the sedimentary features and combined with the analysis and test data of the cores, logging and regional geologic setting data, and observation and description of the reservoir cores of the Zarzaitine Oil Field of Algeria have made. A study of the corresponding relation between sedimentary microfacies and electrical facies has resulted in a division into sedimentary facies of small lapers. According to the distribution features of the sedimentary facies, the space evolutional laws of the sedimentary facies of the reservoir(F4) in this area was analysed and a three-dimensional geologic model was established for the reservoir (F4) of the oil field.
