液氮,作为一种有效的助排剂,正在越来越广泛地应用于试气工艺中。近年来,随着天然气勘探形势的不断发展,液氮助排工艺的应用更为频繁。本文试图通过对几个实例的分析,进而导出在酸化设计中助排剂液氮的用量计算公式,以供参考。实例分析实例1:某井1991年5月酸化时,平均泵压
Liquid nitrogen, as an effective drainage aid, is being used more and more in test gas processes. In recent years, with the continuous development of natural gas exploration, the application of liquid nitrogen drainage technology is more frequent. This paper attempts to analyze several examples, and then derive the amount of liquid nitrogen in the acidification design aid formula, for reference. Example Analysis Example 1: A well was acidified in May 1991, the average pump pressure
