Foam completion fluid is a new type of drilling fluid,which has good environmental performance and application effect.The application in negative pressure perforating has a broad prospect,which can effectively reduce the wellhead pressure,improve the perforating efficiency and reduce the risk of borehole wall collapse.In addition,foam completion fluids reduce bit wear,extend bit life,and reduce drilling costs.Therefore,the application of foam completion fluid in negative pressure perforating will be more widely promoted and applied.
