钛管在深海石油天然气勘探中的应用优势及相关配件

[ 信息发布:本站 | 发布时间:2020-11-02 | 浏览:1905 ]

海上油气开采设备的工作环境相当恶劣,设备首先要与海水和原油、天然气接触,要经受高温氯化物、硫化物、氨等多种介质的腐蚀,最高腐蚀温度可达300℃。其次,设备要承受系统内部的工作载荷和海上风浪产生的冲击载荷。再次,深海油气勘探与开采设备的尺寸都很大,如提升管长达几百米,设备自重很大,对材料的强度、韧性、抗疲劳性能等均有很高的要求。所涉及的用钛装置主要有钻井立管、锥形应力接头、井下作业流送管、增压管道、钻具提升装置、海水管路系统、冷却系统、灭火系统等。所使用的材料有工业纯钛(Grade l、Grade 2) 、Ti-6Al-4V合金(Grade 5、Grade23、Grade28) 、Ti-0.15Pd(Grade7) 、Ti-3A-2.5V(Grade9、Grade 18) 及Ti-38644合金等, 许多钛部件是用大规格或超大规格钛管材制备的。
