永8断块出砂预测及防砂技术的应用

永8断块是1999年总公司重点产能建设区块。该断块油藏地层胶结疏松，各层均存在出砂倾向，是典型的稠油出砂油藏。地层出砂造成油水井不能正常生产。为了保证该区块的正常开发，对该断块的出砂机理、出砂预测、储层及流体等方面进行研究，对防砂技术进行了优化，3年来共应用绕丝筛管砾石充填、金属毡滤砂管、脲醛树脂等防砂工艺施工24井次，累积增油131．268kt，保证了区块正常生产。

Sand Production Forecast and Application of Sand Control Techniques in Yong 8 Fault-Block

Being the priority fault block of oil production of China Petro chemical corporation in 1999,Yong 8 fault block is a typical sand production oil reservoir as it's unconsolidation,existing sand production trend each layor.So in order to insure the normal production,the reservoir's sand production mechanism and forcast method,study on reservoir and fluid were done,the sand control technique were optimizated.Having been used in oil producthing wells,the accumulated oil production is 131 268 tons.
