| 摘 要： | 基于势叠加原理和微元线汇理论,建立了薄互层油藏中阶梯水平井生产段向井耦合流动模型,模型中考虑生产段油藏渗流与井筒变质量管流耦合作用和分支之间的干扰,并形成了考虑生产段耦合流动的阶梯水平井产能评价方法.采用所建立的耦合模型计算的双台阶水平井产能为64.26 m3/d,采用水平井解析公式计算的平均产量为76.27 m3/d.与该井60.19 m3/d的实际日产油量对比,耦合模型的计算误差为6.76%,而采用水平井解析解公式所产生的计算误差则高达26.71%.

| Abstract: | On the basis of the potential superposition, a coupling flow model of the pay zones in stepped hprizontal wells in thin interbeded reservoirs is estabished, and in the model, the interference between reservoir flowing through porous media of pay zones and pipe flowing coupling and branching in well bore is considered, the productivity evaluation method for stepped horizontal wells considering coupling flowing of pay zones is put forward. The dual stepped horizontal well productivity calculated with the established coupling model is 64.26 m3/d, comparing with 60.19 m3/d of the practical productivity of thewell, the calculation error of the coupling model is 6.76%, and the error calculated with horizontal well solution equation is as high as 26.71%. |
