【摘要】 大庆萨北油田油层渗透率低、非均质性严重,原油物性差、粘度高,为改善开发效果,在萨北油田开展热力采油现场试验。结果表明:通过6井次的蒸汽吞吐实验,见到较好的增油降水效果,平均单井日增油量7.8 t,含水下降11.8%,累计增油2820 t。更多还原

【Abstract】 Because of low permeability,more serious heterogeneity,poor physical property and relatively high viscosity of oil in Daqing-Sabei Oilfield,the heat recovery field test was provided in order to improve the development effects.The results show that 6 wells reach better results of increasing oil production through the steam stimulation experiments.The average oil production increases by 7.8 t and the water cut dropped 11.8 %.The cumulative oil increases by 2 820 t.更多还原
