摘　　要：CNPC implements the call of energy conservation and emission reduction, and promotes the application of new energy conservation and emission reduction technologies and new products to achieve production and reduce pollution. As China’s oilfields enter the period of high water cut development, corrosion problem and scale formation ordinary steel tubing are becoming more and more serious in oilfield application, which influence and restrict the production and development and bring about energy waste. FRP tubing has been widely used in oil and gas fields because of its excellent corrosion resistance, small friction coefficient and less wear. With the gradual popularization of FRP tubing in oilfields, failure cases also show a growing trend as threaded release, leakage, fracture and so on, which affect the normal production of oilfields. In this paper, a series of key performance properties affecting service performance of high-pressure FRP tubing are tested which took from common failure cases. The key properties of FRP tubing, such as unloading, anti-collapse, short-term failure pressure at high ambient temperature and high ambient temperature axial tension, are tested in the research. The article provides a scientific basis for applicability evaluation of FRP tubing. This research has important significance for energy saving, decreasing pollution and safe operation of tubing pipes. Several suggestions are put forward on material selection and design of FRP tubing.CNPC implements the call of energy conservation and emission reduction, and promotes the application of new energy conservation and emission reduction technologies and new products to achieve production and reduce pollution.
