Successful Practice of Ultra 1 km Wells Increasing Water Blasting

摘要：

　　Under water blasting main difficulty lies in the explosive brisance and reduce the waterproof difficult under water.This paper introduces the geothermal wells 1 km deep underwater,the successful implementation of blasting methods and measures of increasing water.Mainly elaborated and the use of blasting explosives underwater selection method,the shaped charge technology to improve blasting effect analysis and the design of priming network.At the same time also introduces the field making auxiliary treatment measures of glass steel casing is waterproof,decompression of charge,using thermoplastic pipe insulation of electric blasting network waterproofing measures.Through the auxiliary measures of blasting design,scientific and effective,ensure the successful implementation of the ultra deep water blasting,offering reference for similar blasting engineering.
