摘要

井筒积液是伴随气井生产的常见现象，积液会导致气井产量降低，严重时甚至会使得气井停产。精确的积液预测有助于及时采取措施以减少积液带来的危害，而临界气体流速是气井积液预测的关键。回顾了气井积液预测的相关研究，指出了最小压降模型、液滴模型的局限性，基于现有实验观察认为液膜模型有较好的适用性。考虑到斜井中液膜周向不均匀分布及气相核心中液滴夹带，提出了更符合实际的环雾流模型用于不同管径、不同井斜角下的气井积液预测。基于以往室内实验数据和现场生产数据，将新模型与现有6种积液预测模型进行对比评价。综合考虑模型预测结果正确率及预测误差，认为新的环雾流模型较其他模型预测结果更优，可准确方便地对气井积液进行预测。

Abstract

Liquid loading

which can reduce the gas rate and even kill the gas well

is a common phenomenon associated with gas well production. Accurate prediction of liquid loading will help operators take measures in time to reduce the hazards

and the critical gas velocity is the key parameter to predict the liquid loading in gas wells. The related researches on the prediction of liquid loading in gas wells are reviewed

and the limitations of the minimum pressure drop model and the liquid droplet model are pointed out. Based on the experimental observations

it is considered that the liquid film model manifests better applicability. Considering the droplet entrainment in gas core and the uneven film distribution along the circumference of the tubing in deviated gas wells

a more practical annular mist flow model is proposed to judge the liquid loading of gas wells with different tubing diameters and inclination angles. The previous indoor experimental and field operating data are used to compare the new model with the six existing prediction models for liquid loading. Considering correctness and prediction error of the model prediction results

it is considered that the new annular mist flow model is better than other models

and can be used to predict liquid loading in gas well accurately and conveniently.
