Safety Evaluation and Prediction of Corrosion Status of the Inner Wall of Oilfield Pipeline Based on Monte Carlo Method
With the long-term operation of the pipeline,the inner wall of the oil&gas pipeline encounters with different corrosions,concave points,cracks,scaling,abrasion and other defects,which need to be repaired or replaced in time.In this paper,a new pipeline safety evaluation model based on Monte Carlo method was proposed,in which,having the target pipeline inspected by the in-pipe detector to obtain spe-cific data of related defects,and then,on the basis of analyzing these data,the growth law of corrosion defects was predicted and finally,based on the safety warning model,the internal corrosion of the pipeline was evaluated and its failure time was predicted.
