我国大多数主力油田都属于陆相河流—三角洲沉积储层，如大庆的喇嘛甸、萨尔图和杏树岗等油田，这些油田基本上均已进入高含水后期开采阶段，尤其是以河流相发育为主的主力油层综合含水已达到90%以上，由于多油层砂岩油田存在层间的非均质性，油田的剩余油潜力主要集中在以三角洲前缘相发育为主的薄、差油层中，因此研究三角洲前缘相沉积储层的物性参数解释方法，深化其沉积模式及沉积特征的认识，进而落实油田开发调整潜力，优化调整挖潜方式，对提高老油田最终采收率具有重要的指导意义。

Results show that radial basis function and point interpolation methods possess Kronecker Delta function property, but the robustness is poor in some cases; the MLS approximation function does not possess Kronecker Delta function property, but it has good robustness. Differences among the three discretization schemes of meshless method are as follows:the collocation method requires no numerical integration and very little computational time while its robustness is poor; Galerkin method is not a truly meshless method due to the background meshes required for integration; the Petrov-Galerkin method is a truly meshless method and need numerical integration in each sub-domain, so it needs more computational time.
