Geomodeling technology under multifactor control
Abstract
Abstract: 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 derived 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 lens 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. Key words: structure model, reservoir model, hydrocarbon distribution model, multifactor control, complicated boundary processing, fault processing
