| 摘 要： | 国内外关于水平井产能的研究成果已经非常丰富，但传统水平井模型的建立都基于无限大地层或椭圆形地层。传统模型对于实际气藏中如河流相沉积为主的储层则不适用，这类气藏更适合建立箱式封闭地层模型。根据已有的气体不稳定渗流基本微分方程，求解点源的不稳定渗流问题，通过积分叠加方法给出整个水平井段的压力分布，得到了在整个箱式封闭地层中拟稳态下水平气井的产能方程，为现场计算矩形无底水砂岩气藏中的水平气井产能提供了理论依据。 |

| Abstract: | The researches on the horizontal well productivity at home and abroad have been very rich, but the traditional model of horizontal wells marches for an infinite formation or oval formation. The traditional model is not fit for some actual gas reservoir such as channel sand, which can be described as a box - shaped drainage volume. Based on the existing fundamental differential equation about unsteady gas filtration, we gain a corresponding equation of gas production by integrations of the appropriate point sink functions in the whole horizontal well section. The equation proposed in the paper fills blank of study at home and abroad and provides a theoretical basis for the deliverability calculation of the horizontal gas well in a box - shaped sandstone drainage volume without edge water bottom water. |
| Keywords: | gas Well flow potential horizontal well a point -source solution a box -shaped drainage volume |
