Abstract

ABSTRACT This investigation focuses on the ranking of pipeline leakage susceptibility of two categories of pipeline systems. One consists of three oilfield water-handling pipeline systems and the other consists of five dry crude systems. Online corrosion monitoring (OCM) method was used for both systems, forthermore, in-line inspection (ILI) method, with Magnetic Flux leakage (MFL) tool, was also used for the dry crude systems. The OCM leakage susceptibility potential is derived from the combined severity of general corrosion, pitting corrosion, fluid corrosivity and sessile bacteria population density in the process streams. The ILI leakage susceptibility potential is derived from the average number of corrosion anomalies greater than 10% of the wall thickness and the maximum depth of the anomalies (as percentage of the wall thickness). In spite of such distinctions, the ranking of pipeline leakage susceptibility for the five dry crude pipeline segments turned out to be identical for the two methodologies.

油田管道内腐蚀泄漏敏感性排序方法

摘要本文研究了两类管道系统的管道泄漏敏感性排序。一个由三个油田水处理管道系统组成，另一个由五个干原油系统组成。两套系统均采用在线腐蚀监测(OCM)方法，干原油系统采用漏磁检测(MFL)工具在线检测(ILI)方法。OCM泄漏敏感性电位是由工艺流中一般腐蚀、点蚀、流体腐蚀性和固定细菌种群密度的综合严重程度得出的。ILI泄漏敏感性电位由大于壁厚10%的腐蚀异常的平均数量和异常的最大深度(占壁厚的百分比)得出。尽管存在这些差异，但两种方法对5个干原油管道段的管道泄漏敏感性排序是相同的。
