摘　　要：借鉴国内外蒸汽吞吐技术的开发经验,从地质-油藏工程方案、注采方案、地面(平台)方案几个方面进行研究,并结合现场实施情况进行综合分析。确定了油藏开发方案和注汽参数,研发了地面小型化、撬装化的蒸汽发生器及配套的海水淡化系统、高纯氮气系统,设计了油管注汽工艺、油套环空注高纯氮气工艺、伴注除氧剂的注汽工艺及井筒防腐措施;在海上首次采用了高温电潜泵(耐温250℃)进行热采稠油举升,并对高温井进行温度压力监测;首次在渤海旅大27-2油田进行了稠油先导性试验,取得了较好的试验效果,为下一步大规模开发渤海稠油油田提供了良好的依据和基础。Based on the domestic and foreign exploration experience of steam huff-puff technology,a research was carried out for comprehensive analysis in combination with field practices from several aspects such as geology-reservoir engineering scheme,injection and production scheme and surface(platform)scheme.As a result,reservoir development scheme and steam-injection parameters were determined;ground-miniaturized and skid-mounted steam generators were developed,as well as the supported seawater desalination system and high-purity nitrogen system;oil-tubing steam injection technology,tubing-casing annulus high-purity nitrogen injection technology,steam-injection technology with deoxidizer and shaft corrosion preventions were designed.Electric submersible pump(application temperature of 250℃)was first used for offshore heavy-oil thermal recovery artificial lift to monitor the temperatures and pressures of high-temperature wells.Heavy-oil pilot test was first performed in oilfield LD27-2,Bohai Sea,and obtained favorable pilot results,providing a basis for the next large-scale development of heavy oil fields in Bohai Sea.
