基于地震等时格架的倾角导向储层静态建模方法
A method of dip steering reservoir static modeling based on seismic isochronal stratigraphic framework
摘要
Abstract
When dividing vertical layer is not isochronal and the oil field has sparse well pattern,the accuracy of reservoir parameter prediction in reservoir static modeling will be reduced.Especially in the offshore oil field with a little drilling,it is difficult to establish the reservoir parameter model with high accuracy based on geological statistics method.In order to establish a better isochronous stratigraphic framework and improve the accuracy of reservoir parameter prediction,the method of dip steering reservoir static modeling based on seismic isochronal stratigraphic framework is studied.For the method we establish three-dimensional strata model by dividing vertical layers under the steering of seismic dip cubes,predict reservoir spatial variation from sensitive seismic attributes and combine with well data to establish three dimensional model of reservoir parameters.Comparing with conventional structural modeling methods,stratigraphic framework model under the steering of seismic dip cubes is established in the method.At the same time,the transfer function calculated from seismic attributes to establish reservoir parameter model,which is different from geological statistics method that takes variation function to build reservoir model.And the method can improve the accuracy of reservoir model when the oil field has sparse well pattern.The practical application of an offshore oil field with sparse well pattern shows the method establishes a more isochronous stratigraphic framework than conventional modeling method and further improves the accuracy of the geological modeling.关键词
