Partitioning Algorithm of Reservoir Numerical Simulation Grid for the Complex Structure
摘要
Abstract
As the continuous exploration and development of oil and gas resources,the geological structure of target oil and gas field become more and more complicated. However,the commercial modeling softwares are not ideal,most of which simplify the complex structure and then model it,having a large error. Based on the Cookie-cutter and Stair-Step algorithm,a new hexahedron grid was proposed. This approach introduced the infinite tangent plane,and expressed the geological interface with"near Stair-Step". On one hand,almost all the complex structure can be modeled,including reverse fault,blind fault,multi-Y faults, multi-λfaults,pinch-out and so on. On the other hand,cells preserve hexahedron and have a good orthogonality,which is favor?able to calculate. Further more,the geological interfaces of fault,layer and unconformity are treated with the same method,lowing the algorithm complexity and easy to implement. The algorithm was verified with the local data of complex structure. The results are in line with expectation and meet the requirement.关键词
