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。 According to the geologic characteristics, physical properties of crude oil and development status of oilfield in Gudao Oilfield, the synthesis and performance evaluation of heavy aromatic oil displacing agent and indoor simulated flooding experiments were carried out. According to the experimental results, a field test was carried out in Well N2 81 of Gudao Oilfield in February 1998. By September 2001, a total of 2,406 4 t of oil was added to the test area in September 2001, a total of 32 3 t of oil was added to increase oil recovery The rate of 95%, the average single-well oil 34 37t.
