摘　　要：近年来,我国对天然气的需求量逐年增加,目前的天然气产量已经无法满足人民生产生活需求。为了满足生产以及国民生活的需求,我国对天然气田的开发力度不断加大。随着天然气井开采年限的延长,解决气井积液问题成为各大气田提高产量的关键。解决气井积液的难点在于积液判断的准确性和临界携液流量计算的适用性不高,分析了气井积液机理,总结了气井积液的几种诊断方法,为判断积液问题提供了理论依据。对于水平井3个井段的临界携液模型的研究进行了分类和梳理,提高了模型计算的准确性,对目前模型存在的问题和未来的发展进行了总结。In recent years,my country′s demand for natural gas has increased year by year,and the current natural gas output has been unable to meet the people′s production and living needs.In order to meet the needs of production and people′s lives,my country has continuously increased the development of natural gas fields.With the extension of the exploitation period of natural gas wells,solving the problem of liquid accumulation in gas wells has become the key to increasing production in large gas fields.The difficulty in solving gas well effusion lies in the accuracy of effusion judgment and the low applicability of calculation of critical liquid carrying flow rate.The mechanism of gas well effusion was analyzed,and several diagnostic methods for gas well effusion were summarized,which provided information for judging effusion problems.The research on the critical liquid-carrying models of three sections of horizontal wells was classified and sorted out,which improved the accuracy of model calculations,and summarized the existing problems of the current model and future development.
