摘要
一个合理的三维网格是正确地质体模型的躯体和精髓,决定着地质模型的复杂程度和准确程度。针对储层精细构造模型保持地质特征的网格化技术研究对于中国陆相油气田二次开发剩余油认识具有重要意义。然而商业化建模软件和油藏数值模拟软件没有针对油藏中后期开发油藏精细描述的三维网格化的合理解决方案,建模及数值模拟的效果往往无法满足实际应用。以储层建模及油藏数值模拟软件最为常用的网格形式结构化网格作为主要研究对象,以老油田二次开发油藏精细描述为出发点,最大程度的保持地质特征来进行网格化。保持地质意义的网格化技术为储层精细建模和油藏中后期剩余油预测提供了技术保障。
A properly constructed three-dimensional grid is the body and the soul for a reasonable geological model,which determines the complexity and accuracy of the geological model. Research on the gridding technology of the fine reservoir structure model to maintaining the geological features is very important for residual oil development in the continental oil and gas fields of China. However,there is no reasonable solution for the fine description of reservoir in the middle and later period of reservoir development. The results of the modeling and numerical simulation are often unable to meet the practical requirements. Structured grid is the main research object,which is the most common grid form in reservoir modeling and reservoir simulation software. Based on the starting point of fine reservoir description for the second development of the old oil field,the gridding is done to maintain the geological features to the maximum extent. The method of keeping geological significance of the grid technology provides a technical support for better reservoir modeling and residual oil prediction in the reservoir.
