摘要
多条件约束地质建模技术就是在二维或三维空间建立某种地质属性模型的过程中,不但要考虑该属性数据之间的相互影响,还要考虑其他相关属性数据对该属性数据影响的一种数据处理方法。该技术中的"多条件约束"包含3种基本含义:属性空间约束;属性转换约束;属性校正约束。多条件约束建模的关键技术包括断层封挡技术、多边界技术及标志层约束下的单砂体微构造技术等。对中国不同类型油气田的建模实例表明,充分利用与建模对象有关的静态信息及动态资料,将这些资料作为建模的原始数据或约束条件,灵活应用多条件约束地质建模技术,可较好地解决各种各样的复杂地质建模问题,建立置信度较高的油气藏地质模型。
Geomodeling technology under multifactor control is one kind of data processing for certain attributes modeling, which considers both the attribute data interaction and the other related data influences. So-called multifactor control includes three meanings: the attribute space formed by restrictions from other attributes; attribute deriving from other related attributes; attribute model adjustment by more reasonable models of other attributes. The key points of the modeling technology are processing of all kinds of faults, analysis and processing of complicated boundaries, structure calculation of certain small len formations controlled by structures of typical and large layers nearby etc. Model cases from different types of reservoirs in China indicate that it's easy and efficient for geologists to build delicate and reliable geological attribute models using the technology and by integrating all kinds of data related to the attribute models from static information to performance data into the original data or restriction data for geological modeling.
