众所周知，一些近井筒物理现象，如地层损伤、酸刺激或近井储层非均质性会对油井产能产生重大影响。来评估这种影响。近井筒数值模型已经开发出来，可以使用非常精细的网格块来模拟近井筒物理现象。然而，近井模型通常是独立开发的，并且与油藏模型分离。使用不考虑生产场景的独立近井模型不允许我们正确预测油井注入量或产能。在本文中，我们提出了一种以简单且一致的方式耦合模拟近井流动模型和油藏模型的技术。该方法适用于 3D 异质介质中的多相流。在这种方法中，这两个模型之间的数据通过近井模型的边界条件和油藏模型的数值产能指数（PI）进行更新。非均质介质两相流实例、多层油藏钻井诱发地层损伤模拟、水平井堵水处理等实例表明，该耦合模型给出了令人满意的结果。 (C) 2011 Elsevier B.V. 保留所有权利。
It is well known that some near-wellbore physics such as formation damage, acid stimulation or near-well reservoir heterogeneity can have a big impact on well productivity. To evaluate this impact. near-wellbore numerical models have been developed to simulate near-wellbore physics using very fine gridblocks. However, near-well models are usually developed standalone and are decoupled from reservoir models. Using a standalone near-well model, which does not take into account production scenarios, does not allow us to correctly predict well injectivity or productivity.In this paper, we present a technique for the coupled simulation of a near-well flow model and a reservoir model in a simple and consistent way. This approach is applied to multiphase flow in 3D heterogeneous media. In this approach, data between these two models are updated through boundary conditions for the near-well model and numerical productivity indices (PI) for the reservoir model. Examples, including an example of two-phase flow in heterogeneous media, simulation of drilling induced formation damage in multi-layered reservoir and water shut-off treatment for a horizontal well, show that this coupled modelling gives quite satisfactory results.
