| 摘 要： | 水平井是提高油气井产量的一个重要工具,无论是水平油井还是水平气井,其产能分析方法都是油气藏工程研究的重要内容。利用解析式预测油藏水平井的产能公式比较多,但是对于气藏水平井产能的预测相对较少。本文从气体地下稳定渗流基本原理出发,利用保角变换建立了水平气井产能分析数学模型,并得到气藏水平井的产能公式。在此基础上,分析了水平井段长度、气层厚度等因素对水平气井流入动态曲线的影响。 |
| 关 键 词： | 气藏水平井 保角变换 产能 流入动态 |

| Abstract: | The method for analyzing horizontal oil and gas wells deliverability is an important content to reservoir engi-neering study.Analytic expression is rarely used to predict horizontal gas well deliverability.Based on the fundamental principle of subsurface steady seepage of gas,a mathematical model for analyzing horizontal gas well deliverability is es-tablished by conformal transformation,and horizontal well deliverability formula is also obtained.The effect of horizontal section length and gas reservoir thi... |
