摘要
油田注水开发过程中 ,储层物性、微观孔隙结构和非均质性都会发生动态变化。建立反映储层性质动态变化的四维地质模型对于深化高含水期油田地质特征的认识、预测剩余油的分布规律、提高油田开发效果具有十分重要的地质意义。论文立足于油田开发过程中储层的动态变化 ,以冀东高尚堡沙三段储层建模为例 ,综合不同开发阶段的井网及相应的取心、测井和实验测试资料 ,研究注水过程中储层参数的变化规律 ,应用随机建模方法建立了不同开发阶段的储层三维地质模型 ,对储层四维地质模型的建立进行了有益的尝试 。
During the development of oil fields, the physical properties of reservoirs, microscopic pore structure and heterogeneity are changed with the development of water injection. It is of importance to build a 4 D geological model reflecting the dynamic variation of reservoir properties for recognizing reservoir geological characteristics, predicting the distribution of remaining oil and raising effectiveness in the exploitation of oil fields. Using core, logging and lab analytic data, and taking the reservoir model of member 3 of the Shahejie Formation in eastern Hebei Province for example, this paper studies the variation rule of reservoir parameters during the course of water injection, builds a 3 D reservoir geological model for different development stages by means of stochastic simulation, and makes a useful trial for building a 4 D reservoir geological model, which has gained good effects in practical application to oil fields.
