Preparation and Application of Organic Silicone M odified Polyether Dem ulsifier
摘要
Abstract
According to the Karamay crude oil emulsion prepared in the laboratory ,high efficient silicone modified polyether demulsifier suitable for low temperature application was developed .The appropriate reaction conditions were determined through the single factor experiment as follows :the adding amount of hydrogen silicone oil was 1% of polyether mass ,the amount of catalyst was 0 .4% ,the temperature of condensation reaction was 80 ℃ ,the time of reaction was 2 h .Infrared spectroscopy was used to compare the characteristic peaks of modified demulsifier groups ,analysize changes of demulsifier structure and verify the target product .The dehydration effect on the tertiary oil recovery of Karamay ,aging oil of Liaohe Oilfield and crude oil of Liaohe Shuguang and Daqing was studied .The dehydration rate of Karamay tertiary oil recovery was up to 87 5.% ,and two‐phase separation of tertiary oil recovery was obvious and clear .Conductance rate of dehydrated water was 4 960 μs/cm and 7 010 μs/cm when unmodified demulsifier and silicone modified demulsifier were used .The dewatering effect of silicone modified demulsifier was better than the demulsifier used in site .关键词
