摘　　要：濮城油田进入高含水开发期,随着调剖次数的增多,调剖效果变差,成本费用明显增加。通过室内实验,认为油田开发过程中产生的污泥经改性处理后,具有调剖剂的性能,可以对油水井大剂量深部调剖。2006年对濮城油田卫317块进行了大剂量深部调剖,取得了很好的增油效果,且节约了调剖成本,经济效益明显,值得大力推广应用。Pucbeng oilfield has entered a high water-cut stage. With more profile control conducted,the profile control effectiveness decreased while the cost increased.Through laboratory test,the modified sludge generated during the process of oilfield development is found to be of the per- formance of profile control agent and then is used as deep profile control agent for oil/water well.In 2006,a large scale of deep profile control was applied in Wei 317 block of Pucheng Oilfield and the result showed it has achieved obvious economic benefits with good stimulation effect and low profile control cost and then proved to be worthy of being greatly popularized.
