摘　　要：重庆气矿的部分采输气管线在冬季不同程度地受到水合物冰堵的影响。采取的管线保温,加防冰剂等措施受到一定限制。为此,提出应用集肤效应电伴热技术防治采输气管线水合物冰堵。分析和计算证明:集肤效应电伴热技术是防治采输气管线水合物冰堵的一种安全、高效、施工程序简便的电加热技术。Part of gas production and transportation pipelines in Chongqing Gas Well Area is affected to some extent by hydrate ice barrier in winter.Such measures as pipeline heat preservation and antifreeze increase are confined.Therefore,it is put forward that surface action electrical heating technique is applied to prevent ice barrier in gas production and transportation pipelines.Analysis and calculation results show that the surface action electrical heating technique is a safe,high efficient,simple and convenient technique,which prevents hydrate ice barrier in gas production and transportation pipeline.
