Dynamic analysis and measure suggestion of secondary sand control well clogging with small screen in Bohai oilfield
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.
