压裂充填井产能预测的分析方法
An Analytical Model for Predicting Prudctivity of Frac and Packed Completion
-
摘要: 在压裂充填井表皮因子的组成基础上, 提出了压裂充填井产能预测的拟表皮系数分析方法, 该方法考虑了裂缝伤害、环空砾石和射孔砾石充填对井产能的影响。运用新模型进行了实例计算和分析, 结果表明该模型可满足工程需要。瓶颈裂缝可引起井产能急剧下降, 压裂液滤失也对井动态有一定的负面影响。Abstract: Based on the composition of frac & pack completion skin factor, an analytical model is presented for predicting the productivity. The model takes into account effects of fracture damage, gravel in screen_case annulus and perforation. The results indict that choked fracture and leak off of fracture fluid had a negative effect on well productivity.
