Amoco 公司使用连续油管(CT)完成一个模拟寻找油井落物的试验,并取出井下9500英尺处被卡钢丝(0.108英寸)。该技术被认为处于世界领先地位,它消除了通过传统的钢丝绳打捞作业取出被卡钢丝的风险性。该方法是打捞井下油管内被卡钢丝和电丝的可能的非传统方法。当井筒条件显示其他打捞方法安全系数不大时,用 CT 模拟求取井下被卡物是一种井下打捞 Amoco completed a test using a coiled tubing (CT) to simulate oil well litter removal and took out the stuck steel wire (0.108 in.) At 9,500 feet downhole. The technology is considered a world leader in that it eliminates the risk of removing the card wire by traditional wireline fishing operations. This method is a possible unconventional method of salvaging the steel wire and wire in the downhole tubing. When the wellbore conditions show that the safety factor of other fishing methods is not large, using CT simulation to obtain underground stuck objects is a kind of downhole salvage
