摘要
本文论述了保压岩心油气水饱和度分析技术、实验条件与数据处理方法，研究并建立了岩心准备、气体收集、全直径岩心饱和度分析、洗油等系统流程。据大庆长垣２口保压密闭取心井油气水饱和度资料，绘制了不同油层油水饱和度脱气校正图版，经对比，油水饱和度由常规的８８％，提高到９６％以上，平均提高８％。脱气校正图版相关系数大于０．９７，相对偏差小于５％，图版精度达到９５％。
This artical deals with the analyticl technique experimental conditions, and data processing techniques of oil gas and water saturation analysis on a pressure core. A systematic technology including core preparation, gas collection saturation analysis of whole diameter cores, oil washing, etc. is established. According to the oil, gas and water saturation analysis pressure maintenance sealing cores in two wells in Daqing placanticline, a oil gas free correction chart to oil and water saturation for different oil reservoirs is drawn.By a comparison oil and water saturation has increased from 88% to over 96%, an average increase of 8percentite percentage point, and the correlation factor of gas free correction chart is more than 0. 97, relative deviation is less than 5%, and chart accuracy reaches 95%.
