Study on Wavelet Analysis in Metal Magnetic Memory Forecasts the Fault of Borehole Casing Well


Nearly 70% casing damaged well in complicated fault oil and gas field were caused by geology and engineering. These two factors cause the casing plastically imbalanced by ununiform load that applies on, thus the imbalanced section where stress is concentrated makes casing bending, deformation or breaking. Metal magnetic memory technique was an effective… (More)
