摘　　要：随着我国海上油气田开发的进行,压裂作业向海洋进军是开发技术发展的趋势之一,研究适用于海上高温油藏的海水基压裂液是节约施工成本、缩短施工周期和提高工作效率的关键。国外在胍胶为稠化剂的压裂液和黏弹性表面活性剂清洁压裂液研究的最多,但由于其耐温性不高,限制了其在高温油藏中的应用;国内则在合成聚合物类高温海水基压裂液方面取得突破。分析认为,以速溶聚合物为稠化剂的耐高温中性-弱酸性海水基压裂液是研究的重要方向。With the hydraulic fracturing development of offshore oil field,the research of sea water based fracturing fluid can save construction cost,shorten construction time and raise working efficiency.The research of sea water based fracturing fluid home and abroad was summarized.The guar based fracturing fluids and viscoelastic surfactant fracturing fluids were mostly studied,but the use of them for high temperature reservoirs were limited due to its poor temperature stability in abroad,but some high temperature tolerance sea water polymer fracturing fluid were shown at home.It can be seen that the high temperature resistance,quick-dissolved seawater based neutral-week acidic fracturing fluid will be an important research direction in the future.
