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。
Because of low permeability, more serious heterogeneity, viscosity of oil in ment effects. The Daqing-Sabei Oilfield,the heat recovery field test was poor physical property and relatively high provided in order to improve the developresults 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.
