摘要
针对稠油热力开采时井底温度、压力监测过程中连续管与井口部位的悬挂密封问题,开展了紧凑型连续管井口悬挂密封器的研究,设计了连续管井口悬挂机构,并采用二次序列规划法及田口优化法,对其关键部件卡瓦进行优化设计,通过对比分析两种优化方法确定出卡瓦的最佳结构尺寸。同时通过预制载荷对卡瓦进行室内试验,结果表明,经田口优化方法确定出的卡瓦结构具有较高的可靠性,为紧凑型连续管井口悬挂密封装置现场作业的安全提供保障。
Aiming at the problem of hanging and sealing between the coiled pipe and the wellhead during the monitoring of bottom hole temperature and pressure in heavy oil thermal recovery,the research on the compact coiled pipe wellhead hanging and sealing device was carried out,and the coiled pipe wellhead hanging mechanism was designed.The key components of the coiled pipe wellhead hanging and sealing device were optimized by using the quadratic sequence programming method and the field optimization method.Through comparative analysis of the two optimization methods the optimum size of the outlet slip was determined.At the same time,the prefabricated load is used to test the slip in the laboratory.The results show that the slip structure determined by Taguchi optimization method has high reliability,which provides a guarantee for the safety of the field operation of the hanging and sealing device of the compact continuous tube wellhead.
