Research on Extending Sand Control Period of Screen Fracturing Wells in Bohai Oilfield
The low production and low efficiency oil wells in Bohai Oilfield have great development potential,but conventional measures such as increasing injection and acidification have failed to effectively release the oil well production capacity,resulting in poor oil production efficiency.The screen fracturing technology implemented in recent years has achieved an organic combination of plugging removal,increasing production and sand control.In order to prolong the effective period of sand control in screen fracturing wells,the screen fracturing technology is further optimized and upgraded,and applied in the field.The results show that the production increase effect is good after oil well operation,with a significant increase in flow pressure and a significant increase in liquid production index.In addition,no sand production is observed during the production process,and the effective period of sand control is more than 60 months.
