Abstract

Abstract: In the fracture well of the casing perforation, the fracture was damaged, that is the choked fracture and fluid leak-off damage. An analyzable method was introduced to study the effects of fracture damages on fractured well productivity. The results indicated both can greatly decrease productivity index while choked fracture had more side effects on well productivity. Some measurements must be taken to minish choked fracture and decrease fracture fluid leak off.

Key words: fracture, damage, fracture fluid leakoff, productivity
