摘要 开发了一种模型来预测石油和天然气管道的内部点蚀。该模型基于在实验室高压、高温下油气管道运行条件下进行的实验。有两种输入：施工（管道直径、管道壁厚和管道倾角）和运行（油、水、气体、固体、温度、总压力、硫化氢 [H2S] 和二氧化碳 [CO2] 的分压、硫酸盐、碳酸氢盐和氯化物的浓度）。该模型考虑了点蚀的统计性质，根据现场容易获得的操作参数预测内部凹坑的生长，包括由模型中未包含的变量驱动的凹坑生长速率，考虑点蚀速率随时间的变化，并确定预测中的误差。使用从...获得的数据检查了该模型的有效性。
Abstract A model has been developed to predict internal pitting corrosion of oil and gas pipelines. This model is based on experiments carried out in the laboratory at high pressure and high temperature under the operating conditions of the oil and gas pipelines. There are two kinds of inputs: construction (pipe diameter, pipe wall thickness, and pipe inclination) and operational (production rates of oil, water, gas, solid, temperature, total pressure, partial pressures of hydrogen sulfide [H2S] and carbon dioxide [CO2], concentrations of sulfate, bicarbonate, and chloride). The model accounts for the statistical nature of the pitting corrosion, predicts the growth of internal pits based on the readily available operational parameters from the field, includes the pit growth rate driven by variables not included in the model, considers the variation of the pitting corrosion rate as a function of time, and determines the error in the prediction. The validity of this model was checked using data obtained fro...
