【摘要】：蒸汽辅助重力泄油(SAGD)工艺已成为辽河油田超稠油开发的一项重要技术。SAGD注汽采用直流锅炉组合汽水分离器技术,得到95%以上高干度蒸汽,同时分离出25%的高温分离水,造成热量浪费。为进一步改善SAGD开发效果,提高经济效益,辽河油田SAGD开发决定采用过热蒸汽注入技术,提高蒸汽有效利用率。经国内外技术调研,结合超稠油开发实际情况,确定了汽包锅炉产生过热蒸汽的技术思路。汽包锅炉对水质要求较高,普通的污水处理水质达不到汽包锅炉进水标准,通过对比国内外去离子水制备技术,并结合超稠油采出水性质,采用机械压缩蒸馏(MVC)技术处理超稠油污水,提高污水水质,解决超稠油污水回用汽包锅炉的瓶颈问题。MVC工艺主要分为预处理单元、升温单元和压缩蒸发单元。该技术的试验成功将为辽河油田规模实施SAGD提供强有力的技术支撑。
[Abstract]:Steam assisted Gravity discharge process has become an important technology in the development of super heavy oil in Liaohe Oilfield .SAGD steam injection using combination steam separator technology of once-through boiler to obtain more than 95% of high dry degree steam, at the same time separating 25% of high temperature separated water. Waste heat. In order to further improve the effect of SAGD development and increase economic efficiency, SAGD development in Liaohe Oilfield decided to adopt superheated steam injection technology to improve the effective utilization rate of steam. Through technical investigation at home and abroad, combined with the actual situation of super heavy oil development, the technical thinking of producing superheated steam in drum boiler is determined. The water quality of drum boiler is very high and the water quality of ordinary sewage treatment can not reach the standard of inlet water of drum boiler. By comparing the domestic and foreign deionized water preparation technology and combining with the characteristics of super heavy oil produced water, The technology of mechanical compression distillation (MVC) is used to treat super heavy oil sewage, to improve the water quality and to solve the bottleneck problem. MVC process is mainly divided into pretreatment unit, heating unit and compression evaporation unit. The successful test of this technology will provide strong technical support for the scale implementation of SAGD in Liaohe Oilfield.
