重芳烃驱油剂的研制及应用

Development and Application of Heavy Aromatic Hydrocarbon Displacement Agent

针对孤岛油田普通稠油油藏地质特征、原油物性条件及油田开发状况 ,进行了重芳烃驱油剂的合成、性能评价和室内模拟驱油实验。根据实验结果 ,1998年 2月在孤岛油田N2 81井区进行了矿场试验 ,到 2 0 0 1年 9月试验区累计增油 2 40 6 4t,合计吨药增油 32 3t,提高采收率 1 95 % ,平均单井增油34 37t。

Based on the geologic features of general heavy oil reservoirs, crude oil physical conditions and oilfield development situation, synthesis of a heavy hydrocarbon displacement agent, its property evaluation and laboratory simulation displacement testing are performed. According to the results, in February 1998, a field testing was carried out on Well N28-1 in Gudao Oilfield, by the end of Sept. 2001 the total oil production increased to 24064 t, oil production increase of each ton of displacement agent was 32.3 t, oil recovery enhancement was 1.95%. oil production increase of a single well was 3437 t.
