摘要
胡状集油田是严重的非均质油藏,含水高,油层埋藏深且矿化度高,单一的调剖效果越来越差.为了克服这些难题,提出了双向调堵技术,通过室内实验优选出一种新的交联聚合物体系,评价不同调堵形式的开发效果,验证了双向调堵具有相对的优越性,较之单一的调剖或者堵水,可提高3%采出程度.将该技术应用于现场试验,并取得了显著的增油效果.
Huzhuangji oilfield is a highly heterogeneous reservoir,with high water cut,deep reservoir burial and high salinity,single profile control is getting poorer results.In order to overcome these problems,a bi-way profile-adjusting and plugging technology is proposed,a new crosslinking polymer system is developed through the indoor experiments.Through evaluation of different profiling-plugging methods,the bi-way profiling-plugging is relatively advantageous,recovery degree can be improved by 3%when compared with single profile control or water plugging.Its field application has obtained remarkable effects in oil recovery increase.
