水平气井产能敏感性因素分析

Analysis on Sensitivity Factors of Horizontal Well Productivity

随着越来越多的水平井应用于天然气藏,选定准确预测水平气井产能公式意义重大。本文从水平井长度和宽度两个方面对水平气井产能计算的敏感性进行了分析,建议根据敏感性因素选择适合本地区的产能计算公式。

As more and more horizontal wells are used in the development of gas reservoirs,how to select proper formula to predict horizontal wells productivity is great important.In this paper,the sensitivity of productivity calculation for horizontal wells was analyzed from two aspects of horizontal well length and width.It was recommended that productivity formula should correctly be chosen by the sensitivity factors.
