海外河油田堵水技术
RESEARCH AND APPLICATION OF WATER SHUTOFF TECHNOLOGY IN HAIWAIHE OILFILED
-
摘要: 海外河油田为注水开发稠油油田,1989年投入开发以来,受笼统注水及边底水的影响,油田综合含水逐步上升,综合含水已近80%,限制了油田的高效开发。从油田地质分析出发,针对高含水油井的特点,确定了油井堵水选井原则及相应的堵水工艺,并重点对F908系列堵水剂进行了室内性能评价和应用效果分析。结果表明:目前应用的堵水工艺能够满足海外河油田稳油控水的需要。Abstract: Since 1989, the viscosity oilfield of Haiwaihe has been developed, the water cut has been raised step by step which being affected from water flooding, edge water and bottom water driving. Now, the water cut is nearly 80 percentage and restricts oil development. The water shutoff technology and its well selecting method has been confirmed according to the character of the wells and oilfield geology analysis. The series water shutoff agent of F908 were evaluated in lab and the field application effect were analyzed. The result shows that this water shutoff technology can meet the need in Haiwaihe oilfield.
