Reservoir iterative modeling constrained by dynamic data

Key words:  reservoir model  reliability  history matching accuracy  matching contradiction between static and dynamic data  iterative modeling

Abstract:

Based on reservoir geological modeling and numerical simulation technology, a reservoir modeling method constrained by dynamic data was researched and applied to the south area of the upper member of Cuantao formation, Chengdao Oilfield. The results show that the presented reliability characterizing method of reservoir model can accurately describes the reliability of overall and local model in a quantitative form. The cause of reservoir model unreliability can be confirmed quickly by using exclusive method and analyzing matching contradiction between static and dynamic data. The reservoir model can be constrained and modified by using iterative method. The mutual infiltration and effective integration between geological modeling and numerical simulation technology are realized. The reliability of ihe reservoir model can be greatly improved.
