Abstract: This paper formulates the change of dynamic parameters during cementing displacementthrough analysing and studying the dynamic process of cementing. On this basis,computersimulation and computer aided design software of a cementing process are developed.The development of the software provides a powerful supporting tool and means for making cementing design and guiding the cementing operation. Through testing and verifying in severalwells on site,the simulation and measurement results are almost identical.

摘要： 本文通过对注水泥动态过程的分析研究,建立起了描述这一动态过程的模拟模式;在此基础上研制开发了注水泥动态过程计算机模拟与辅助设计软件。从而为指导固井施工和固井设计提供了有力的支持工具和手段。通过数口井的现场验证,模拟结果与实测值的相符程度很高。
