摘要
大庆油田中区西部、杏五区三元复合驱先导性矿场试验和正在开展的北一断西、杏二区扩大矿场试验均见到较为明显的增油降水效果。为了科学、合理地评价三元复合驱矿场试验效果,根据正方形面积、流线面积和饱和度变化情况对其采收率进行了初步评价,结果表明,注采比对三元体系波及范围有重要影响;流线法和含油饱和度法所得的采收率值能较好地反映模拟三元复合驱效果的实际。三次采油的采收率评价需要建立一套技术指标、经济指标评价方法,三元复合驱采收率计算方法尚需深入分析。图2表1参3(郭海莉摘)
Both ASP pilot tests in Block Xing 5 in western region of central part and in western fault block in northern first part and Xing 2 part have shown clear results of production increase and watercut declining. In order to evaluate the results of these pilot tests scientifically and reasonably, a preliminary appraisal based upon the area of respect square and the change of the area of stream lines as well as recovery efficiency were made. Results show that injection production ratio has a significant effect on the swept area; and recovery efficiency obtained by stream line method as well as oil saturation method can better reflect the actual effect of the simulated ASP flooding. An evaluation method for a system of technical and economical indices should be established, and method of calculating the recovery efficiency should be analyzed more deeply.
