摘要
海上平台安全使用期有限及油藏非均质性严重造成的高含水率是制约滩海油田开发的主要因素。为此，研制出了能够满足海上油田在线调剖所需的乳液调剖体系，并开展了室内评价和研究。结果表明：该调剖体系溶解时间短，注入性好，具有缓交联、增黏性好等特点。乳液在线调剖体系在埕岛油田开展了5口井的在线调剖试验，均获得了较好的效果。
Abstract
The high water content caused by reservoir heterogeneity and the limited lifetime of offshore platform are the major factors to restrict the seabeach oilfield development. So we have developed the emulsion profile control system to meet the needs of on-site profile control for offshore oilfield. And laboratory evaluation and study are carried out. Study results show that the profile control system is characterized by the short dissolving time, good injectivity, slow cross-linking and strong viscosity. The field test of on-site profile control system of emulsion has been carried out in 5 wells in Chengdao Oilfield, which have gained a fairly good effect.
