STUDY AND APPLICATION OF THE DRIFTING AND REAMING WORKOVER TOOL
The main reason causing the low restoring rate of the small gauge casing damaged wells in Daqing Oilfield is the inefficiency of drifting and reaming technology.Based on this condition,two types of 8 kinds tools were developed,and these tools can be field assembled into 5 kinds auxiliary BHAs.Field application showed that the restoring rate could be improved up to 92% or over.
