摘要
文章通过归纳分析多口小筛管二次防砂井堵塞动态规律,对堵塞源、堵塞机理及堵塞位置进行分析.分析结果表明:二次防砂系统过流面积管理、储层保护、原筛管外环空充填率、原完井系统内的堵塞物处理是小筛管二次防砂完井油井堵塞管理关键.以上结论为小筛管二次防砂井生产异常问题分析提供思路.
Abstract
In this paper,the plugging source,plugging mechanism and plugging position are analyzed by summarizing and analyzing the plugging dynamic law of multi-hole small screen secondary sand control well.The analysis results show that the flow area management of secondary sand control system,reservoir protection,the filling rate of the outer annulus of the original screen and the blockage treatment in the original completion system are the keys to the plugging management of the small screen secondary sand control completion system.The above conclusions provide ideas for the analysis of production anomalies in small screen secondary sand control Wells.
