鄯善油田的蜡碳数高,分布有两个高峰区,且高碳区蜡不溶于CS_2,几乎为纯的正构烷烃。本文通过对鄯善油田结蜡规律及蜡性的分析研究,结合生产需要重点介绍了内衬油管配套防蜡技术以及在鄯善油田的应用。通过一年的现场试验,内衬油管防蜡技术取得了较好的经济效益,与其配套的短循环热洗清、防蜡工艺也获得了较好的效益。 Shanshan Oilfield has a high wax carbon number with two peak areas and the high-carbon wax is insoluble in CS_2 and is almost pure n-alkane. In this paper, through analysis of the waxing property and waxiness of Shanshan Oilfield, the paper introduces the wax-supporting technology of lining oil pipe and the application in Shanshan Oilfield. After one year’s field test, the lining oil pipe wax prevention technology has achieved good economic benefits. Compared with the short circulation heat washing and wax protection technology, the lining oil well achieved good benefits.
