摘　　要：双河油田Ⅴ上层系是河南油田第一个高温聚合物驱先导性试验单元,于2004年5月13日开始注聚,在整个注聚过程中先后开展了:完善注采井网、注聚前深度调剖、"一井一制"注入、注聚期间的跟踪调整与调剖、油井压裂解堵引效等动态调整工作,促进了聚合物驱效果的不断扩大。至2007年11月共注入聚合物溶液0.4141PV。对应油井见效24口,油井见效率达82.8%,日产能由注聚前的92t到目前的170.3t,含水由95.38%下降到92.08%,高温聚合物驱先导试验取得了初步成效,为河南油田"十一五"期间动用3215.3×104t二类聚合物驱储量和三采产量接替奠定了基础。Based on the situation of waterflooding in Shuanghe Oilfield,by using II1-2 unit in Block 437 for example,numerical simulation was carried out on the basis of precision description of reservoirs.In combination with reservoir engineering,dynamic analysis,the control factors of remaining oil and its distribution rules after polymer flooding were studied,and the adaptability of the available well pattern was evaluated.The mode of well pattern reconstruction suitable for tapping the potential of remaining oil is proposed for its application at the late stage,certain effect is obtained,it is of great significance of similar reservoir development.
