我院化工系徐家业副教授负责的“热采添加剂”课题组,在广泛调研国内外资料的基础上,于1986年10月开始进行蒸汽吞吐添加剂的研究。1987年4月我院与南阳油田勘探开发研究院达成合作研究协议。我院负责化学剂的合成、复配,性能研究与初步筛选;油田负责物模试验与现场试验,由孙玉亭高工负责。1989年5月完成了室内试验,筛选出一类具有优良降粘性、耐高温性与驱油效果好的热采添加剂。物模试验在200℃,添加剂浓度800ppm。注入4PV时,驱油效率比蒸馏水驱一般提高15个百分点,最好达24.5个百分点,1989年7月顺利通过了油田的鉴定阶段。 1991年11月油田落实了现场试验经费,热采添加剂由西安石油化工厂试制生产。由于我院科研人员在合成上进行了大量研究工作,并赴现场进行指导,使试生产一次成功,试产产品性能达到并超过了实
The research group of “Thermal Recovery Additives”, an associate professor of Department of Chemical Engineering in our hospital, conducted research on steam stimulation additives in October 1986 on the basis of extensive research on domestic and foreign materials. In April 1987, our hospital and Nanyang Oilfield Exploration and Development Research Institute reached a cooperative research agreement. Our hospital is responsible for chemical synthesis, compounding, performance and preliminary screening; oil field model test and field trials, by Sun Yuting Gaogong responsible. May 1989 completed the indoor test, screened a class with good viscosity reduction, high temperature resistance and oil displacement effect of thermal recovery additives. The physical model test at 200 ℃, additive concentration of 800ppm. Injecting 4PV, the flooding efficiency is generally 15% higher than that of distilled water flooding, preferably up to 24.5%. In July 1989, it passed the appraisal stage of oilfield. Oil field in November 1991 to implement the field test funding, thermal recovery additives trial production by the Xi’an Petrochemical Plant. Because of our research staff in the synthesis of a large number of research work, and went to the scene to guide the pilot production of a successful pilot product performance to meet and exceed the real
