摘要
As the main consumables, huge amount of tubing and sucker rods are abandoned annually. The current remediation technology could only enable part of abandoned tubing and sucker rod to be reused in a degraded way, leading to a big resource waste. The production, use and remediation methods of tubing and sucker rod are analyzed here. Remanufacturing technology of abandoned tubing based on self-propagating high temperature synthesis (SHS) is proposed. Economic, environmental and social benefits of large scale application of this technology are evaluated. And then various factors that restrict the popularization of remanufacturing technology in the petroleum industry are studied and suggestions are given in the end. The results indicate that unlike conventional remediation methods, remanufacturing technology can extend the service life of abandoned tubing to reach or even exceed that of a new one. Meanwhile it can also reduce the cost effectively, and achieve significant economic and social benefits. We should expand remanufacturing technology areas in the petroleum industry and achieve stable, healthy development in the low oil price situation. The scientific standards for remanufactured products should be enacted, and new management mode of the remanufactured products should be developed.
