摘要
近年来随着对深水钻井技术不断的探索研究,喷射导管钻井技术越来越得到广泛的应用。目前对喷射导管的研究中,由于时间效应的复杂性,其安装后实时承载力未能得到很好的解决。为此,本文利用有限元数值模拟方法对深水喷射导管的实时承载力进行分析,对现有的经验计算公式进行了改进,结合塑土的强度恢复试验,实现了导管实时承载力的计算。
In recent years, the technology of deep-water jetting drilling is being used more and more widely with the unceasing research of deep-water drilling technology. On current research of the jet pipe, due to the complexity of time effect of bearing capacity, the research have not a very good solution for the real-time bearing capacity. Therefore, in this paper the finite element numerical simulation method for the capacity of deep-water jetting has been used, the existing experience calculation formula for the ca- pacity of jet pipe has been improved, and the calculation of through the recovery strength test of the remoulded soil. bearing capacity with time has been solved
