摘　　要：在地热井开发过程中,解决结垢问题的常用方法是使用化学阻垢剂。对地热井中结垢的分布和厚度进行研究,对于确定井的结垢速率和结垢厚度有重要意义。采用Pipesim和Oil ScaleChem软件进行模拟计算,通过调整温度、压力、流量等变量以获得结垢速率和厚度的数据。通过使用数据分析和拟合技术确定了反应动力学参数的值,并建立了井筒结垢厚度预测模型。基于该模型开发的预测软件能够提供一年以上的结垢厚度和速率预测,为制定相应的阻垢策略提供便利。对四口地热井的结垢厚度预测的准确度都达到了90%以上,在地热井开发领域具有很高的理论和实践价值。In the process of geothermal well development,chemical scale inhibitors are commonly used to solve the problem of scale forma-tion.It is of great significance to study the distribution and thickness of scale formation in geothermal wells for determining the scale formation rate and thickness of wells.Pipesim and Oil ScaleChem software were used for simulation calculation,and the scaling rate and thickness data were ob-tained by adjusting temperature,pressure,flow rate and other variables.The values of reaction kinetics parameters were determined by using data analysis and fitting techniques,and the prediction model of wellbore scaling thickness was established.The prediction software developed based on this model can provide more than one year's prediction of scaling thickness and rate,and facilitate the formulation of corresponding scaling preven-tion strategies.The accuracy of predicting the scale thickness of geothermal wells is more than 90%.This research has high theoretical and practical value in the field of geothermal well development.
