| 摘 要： | 在水平井开发可行性论证及水平井优化设计中，水平井产能预测是决策方案的重要依据。实际计算分析表明，目前常用的水平井产量公式计算结果偏高，与实际值相差较大；具原因在于公式推导中假定地层是均质的、流体做单相流动等。通过考虑储层表皮系数、非均质性、多相流等影响水平井产量的因素，提出了校正产量公式的方法，校正后公式的预测结果与实际值接近，提高了水平井产能的预测精度。

| Abstract: | The horizontal well productivity prediction is an important basis in the feasibility demonstration of horizontal well development and its optimizing designing. The actual calculated results indicate that the calculated productivity using the commonly used prediction equation is higher than the actual value by a huge difference. The reason is that the derived equation assumes the formation is homogeneous and fluid flow is single phase. Through considering formation skin factor, heterogenousity and multi phase flow etc, a modified productivity equation was proposed in this paper. The predicted productivity using the modified equation is closer the actual value and the prediction precision of horizontal well is improved. |

| Keywords: | horizontal well multiphase flow productivity forecast accuracy |
