一种适用于动力定位装置的新型深水测试管柱

A Kind of New Deep Water Well Testing String Being Suitable for Dynamic Positioning Device

对于动力定位的深水作业平台,在海上始终处于动态稳定过程,而一旦定位失效,隔水管则需解脱,以便平台能够自由漂移。隔水管的解脱要求其内部的作业管柱也能解脱,由此对深水测试管柱提出了要求,相对于常规测试或浅水测试,深水测试管柱最大的不同点是使用了快速响应的深水水下树。正是由于深水水下树的使用,以及深水的自身特点,深水测试管柱在功能要求、安全要求、可靠性要求等方面都有所提升,独具特色。

Platform for dynamic positioning of deepwater operations,remains stable at sea,and when it is failure,riser is needed relief so that platforms are free to drift. Release of the Riser requires its internal operation string can be free,which presents some demands to testing string in deep water. Relative to the conventional testing or shallow water testing,the biggest difference for testing string in deep water is the use of quick response of deepwater subsea trees. Just because of usage of it,as well as the characteristics of deep water,testing string of the deep water in areas such as functional requirements,safety requirements,reliability requirements have been improved and are unique.
