摘　　要：为评价化学剂M2ES矿场驱油效果,通过在化学剂注入前、期间、后分别注入不同示踪剂,对连通的7口油井连续取样、化验,判断化学剂注入前后优势注水方向改变情况,分析注入化学剂前后对地层改善作用,评价化学剂驱油效果。结果表明,化学剂注入前,井组平面非均质性严重,化学剂注入过程中平面改善效果显著,化学剂注入结束改注水后平面非均质性有所增强,整体看地层注入化学剂前后起到较好的调整效果。证明示踪剂监测技术可为化学剂驱油效果评价提供准确依据。In order to estimate the application effect of M2 ES chemical flooding,different kinds of tracer agent are injected into reservoir before,during and after the chemical flooding. Then seven connective wells are sampled and tested continuously to judge changes in the advantage water direction,assess the effect of oil displacement. According to the research,the plain heterogeneity of well array is serious before the chemical injection,it has obvious effect during the chemical flooding,but it in enhanced when chemical flooding is changed to water flooding. As a whole,the chemical flooding plays an important part in adjusting plain heterogeneity. The monitoring technique of tracer agent would provide an accurate basis for analyzing the effect adjusting plain heterogeneity of the chemical flooding.
