摘要
油、套管和井下组件的微小渗漏,给油气井泄漏源位置的确定带来了很大的挑战。流体(液体或气体)发生渗漏,出现紊流现象时,会产生高频超声波。通过检测超声波的强度,能够精准地定位泄漏源位置。尽管渗漏量微小至0.02升/分钟,泄漏源位置能够被精准定位至几英寸误差范围内。实例说明,与常规检测技术相比,超声找漏测井能够直观、准确地判断井下泄漏源位置,为渗漏补救措施的选择提供依据。
The detection of the source with extremely small leaks in tubing,casing and other well components presents a huge challenge to the industry.When a fluid(liquid or gas) leaks,it produces a turbulent flow which has strong ultrasonic components.The source can be pinpointed by picking up the acoustic energy,and it can be detected with an accuracy of inches although the leak is as small as 0.02 Liters per minute.Comparing with the conventional technology,the ultrasonic based leak detection log can provide clear,unambiguous log response to identify the precise location of leaks,and the most effective remedial intervention can be confidently selected.
