摘要
固井是一项复杂的系统工程,合理控制固井施工参数是固井施工成功的关键。在固井施工过程中,对注水泥过程的动态参数进行实时监测有助于及时了解井内实际情况,完善施工技术措施,提高固井质量。建立了注水泥过程中环空动压力的计算模型,介绍了其求解过程;开发了具有数据存储、数据处理、数据显示与异常报警功能的固井实时监测系统。通过现场的实际应用,结果表明,整个系统所建立的模型是正确的,功能是有效的,误差较小。
Well cementation was a complex systematical engineering, rational controlling the well cementation parameters was the key of success. In the process of well cementation construction, real-time monitoring the dynamic parameters of the cementing process scan help find out the practical situation,perfect the cementation technical measures,improve the cementation quality. A spatial dynamic pressure computation model was established, its solution process was introduced, a cementation real-time monitor system with the data storage, processing, demonstration and the warning function was developed. Practical applications result indicates that the model of overall system is correct, the function is effective,the error is small.
