美国ICT公司生产制造的拔套管机是一种全新的设备。在美国，用拔套管机起出报废井中、固井水泥返高以上的油层套管。常规情况下，油田在勘探、开发时均会产生部分报废井，但因井中套管被固住，因而无形中增加了油田的开采成本。目前，充分地使用拔套管新技术，对节省钢材，降低油田的开采成本均十分有效。 American ICT company’s production of pull-casing machine is a new kind of equipment. In the United States, the casing pipe is used to lift the casing of the oil well above the level of the cementing cement in the scrapped well. Under normal circumstances, the oil field will have some scrapped wells during exploration and development. However, due to the fact that the casing in the well is fixed, the production cost of the oil field is virtually increased. At present, the full use of the new technology of drawing pipe is very effective in saving steel and reducing the mining cost of the oil field.
