摘　　要：随着国内老气区开发的不断深入,气井出水积液问题日益严重.为了对气井积液严重程度进行准确评估,并为气井排水采气工艺方式的选择及方案设计提供可靠积液量预测参数,在对原预测模型存在问题系统分析的基础上,综合考虑多种因素,建立了油管内积液量和环空积液量预测新模型.新模型理论依据充分,有效解决了原模型计算过程中由参数经验取值带来的不确定性.通过13口探液面气井的对比分析,新模型计算值与实测值吻合程度较好,计算精度较高.With the development of the old gas fields and blocks at home, the problem of loaded water production in the gas wells has become more and more serious. In order to accurately evaluate the degree of the loaded liquid problem and provide the reliable production-predicting parameters for the selection and program design for the tech- nical forms of water displacement and gas production of the gas wells, the new predicting models for the loaded pro- duction in both the oil tubing and annulus are established by considering the integrated factors and on the basis of the systematically analysis of the existed problems in the original predicting models. There are sound theoretical evi- dences in the old new models, the uncertainty resulted from the obtained values by the empirical parameters has been effectively solved in the calculation process of the original models. By the contrasts and analyses of detected liquid levels in 13 gas wells, the coincidence between the calculated and tested values is much better and further- more the calculation precision is also pretty higher in the new models.
