陆梁油田陆9井区白垩系呼图壁河组薄层底水油藏是目前国内外比较特殊的油藏类型，底、边水分布范围大，储层厚度不大，对此类油藏产量的递减分析鲜有报道。文章回顾了Arps模型的使用情况，针对陆梁油田薄层底水特征介绍了Orstrand—Weng模型和T模型两个水平井产量递减分析的新模型，并对该油藏的水平井产量递减阶段进行了对比分析。比较得出，三个模型均可用于预测该油田产量，其结果与实际数据符合，且新模型较之Arps模型不需要分类讨论。

Hutubihe bedset reservoir at Luliang oilfield Lu 9 area is a special bottom water reservoir in domestic and broad. Edge water and bottom water are widely distributed with complex changes of oil bearing, analysis of such a production is significant special. This paper look back to Arps model and introduces Orstrand-Weng and T model for decline analy- sis of horizontal wells in Luliang oilfield. The result suggests new models are suitable for predicting the performance of the wells in Luliang. It is in accord with the actual data from the oilfield and be more convenient to applied with.
