Application of Carbon Fiber Continuous Rod in Block X
摘要
Due to the increase in the proportion of eccentric wear of pumping rods and tubing, the shortening of pump inspection period and the high maintenance operation cost of lifting technology, the field application test of carbon fiber continuous rod was carried out. Carbon fiber continuous rod is a new type of material with low density, high strength and good wear resistance. It can reduce the suspended point load, improve the wear resistance, tensile strength and corrosion resistance of the rod string, reduce the energy consumption of the pumping well, and realize the efficient and low-cost operation of the pumping well. In the field test of Block X, 6 Wells were applied, and the suspended point load was significantly reduced: The maximum load decreased by 11.89 kN on average, the minimum load decreased by 10.34 kN on average, the system efficiency increased from 34.11 to 38.47%, the power consumption of 100 m tons decreased from 0.94 to 0.68, the power saving effect was obvious, and the average power saving rate reached 27.1%, providing a new technical way for the energy saving and efficient lifting of the pumping unit.
