چکیده

امروزه میزان مصرف انرژی در کشور ایران بطور چشمگیری افزایش یافته است. انرژی گاز یکی از مهمترین آنها بشمار میآید. مصرف گاز تا سالهای آینده بطور فزایندهای افزایش خواهد یافت و خطوط انتقال آن نیز بسرعت  رو به  گسترش است.
طول این خطوط در شبکه گاز رسانی به  هزاران مایل  نیز میرسد و اطمینان یابی و کشف بموقع نقص هر بخش از خطوط لوله مهم و ضروری است. این مقاله مروری بر تکنولوژی کنونی کشف نشت از خطوط لوله گاز دارد و نقش سنجش از دور و استفاده از روشهای هوایی را  در کشف این مهم خاطر نشان مینماید.
در بخش اول روشهای متفاوت کشف نشت که در خطوط لوله گاز بکار میرود بطور مختصر مرور میشود و در بخش دوم به روشهای نوری و استفاده از سنجش از دور و روشهای هوایی جهت کاهش هزینه و سرعت انجام نشت یابی مناطق وسیع پرداخته میشود. در پایان، ضمن جمعبندی، روشهای کشف نشت با هم مقایسه میشوند.

چکیده [English]

Nowadays, energy use has increased dramatically in Iran. Gas is one of the most important energy resources. Gas use will grow in future and its pipe lines are quickly developing. The length of this gas distributing network reaches thousands of miles, so validating and timely defect detection in each part of pipe line is important and essential. The present article reviews current technology of leakage detection in pipe lines and points out the role of remote sensing and aerial methods in this detection.
In the first section, different leakage detection methods applied on gas pipe lines are shortly reviewed and the second section focuses on optical methods and applying remote sensing and aerial methods with the aim of decreasing costs and time of leakage detection in vast areas. Finally, different methods of leakage detection are compared in the conclusion.
