根据辽河油田J16区块实际资料，建立了30 cm × 30 cm × 1.5 cm 的平面非均质和30 cm × 15 cm × 10 cm 的纵向非均质水平井化学驱物理模型。通过开展水平井化学驱物理模拟与数值模拟综合研究， 初步分析了水平井化学驱的驱油机理与生产动态，并提出注采水平井方向应尽可能平行于河道走向，采 用平面上注入井布在高渗带、采油井布在低渗带，纵向上底层注顶层采的布井方式以及二元驱的驱油方 式开发效果最好。

Based on actual data from J16 block in Liaohe Oilfield, this paper established physical models of 30 cm× 30 cm×1.5 cmareal heterogeneity horizontal well and 30 cm×15 cm×10 cmvertical heterogeneity horizontal well. We carried out physical simulation and numerical simulation of horizontal well chemical flooding, and analyzed the oil displacement mechanism and production performance of horizontal well chemical flooding. It is concluded that the direction of horizontal well should be paralleled with the river channel trend, horizontal injection well should be deployed in the high permeability zone and horizontal production well should be deployed in the low permeability zone in plane, horizontal injection well should be deployed in lower location and horizontal production well should be deployed in higher location in vertical, and polymer and surfactant combination flooding is recommended.
