Abstract

An important task in reservoir simulation is to take into account the effect of a hydraulic fracture on the well’s performance. The upscaling method allows efficiently computing the inflow into a well with a fracture on a coarse grid. A numerical near-well upscaling procedure for hydraulic fractures on an unstructured Voronoi grid is proposed. The upscaling procedure is shown to be significantly more accurate than the classical EDFM method.

近井放大模拟水力压裂井

摘要

储层模拟中的一项重要任务是考虑水力压裂对油井性能的影响。放大方法允许有效地计算流入具有粗网格上的裂缝的井的流入量。提出了非结构化Voronoi网格上水力压裂的数值近井放大方法。事实证明，升级过程比经典的EDFM方法要准确得多。
