无立管轻型井修井 (RLWI) 相较于基于立管的修井方式具有诸多优势。传统上,无立管模式下只能进行电缆作业和钢丝作业。因此,如果需要连续油管 (CT),通常需要切换到基于立管的修井方式。无立管连续油管 (RLCT) 的引入解决了这个问题,增强了各种作业的能力。

Riserless light well intervention (RLWI) offers several advantages over riser-based intervention. Traditionally, only wireline and slickline services could be performed in riserless mode. Thus, if coiled tubing (CT) were required, typically it was necessary to switch to a riser-based intervention. The introduction of riserless coiled tubing (RLCT) addresses this issue, enhancing capabilities for a wide range of operations.
