不同非凝析气对稠油高压物性的影响
The Influence of Different Non-Condensate Gas on High Pressure Property of Heavy Oil
摘要
Abstract
The southern part of Qinhuangdao 33-1 oil field is a heavy oil field which has not been exploited.The mode of thermal recovery is considered unusually in the early of exploitation.The design of thermal recovery mode depends on mass experimental data.Based on the indoor physical simulation,the influence of different non-condensate gas on high temperature and high pressure property of heavy oil is studied with a set of experiment instrument which support high temperature and high pressure.The results show that the volume ratio of CO2 dissolved in heavy oil of the southern part of Qinhuangdao 33-1 oil field is higher than N2 obviously,and the reduction rate of CO2 is 30%~90%.The lower temperature and greater pressure make CO2 reduce the viscosity of heavy oil more effectively.In different experiment temperature and pressure conditions,the N2 viscosity reducing extent is lower than 20%,and the dissolving capacity and viscosity reducing effect of flue gas is between N2 and CO2 .关键词
