Research on Well Completion Technology Combined Drilling with Blasting

Abstract:

Based upon cavity effect of explosive, researching and manufacturing a tool breaking erratic in well and combining with wallscraper drilling resolved large diameter well completion technology in erratic stratum and improved drilling efficiency from several times to dozens times and quickened the speed of well completion. Principle, structure and application results of tool breaking erratic in well, and feature and points for attention of well completion process combined drilling and blasting are introduced in the paper.
