Design of Abrasive Water Jet Perforation and Hydraulic Fracturing Tool
The operating principle of the Abrasive Water Jet Perforation is to build up a water jet channel on casing by machinery buck and to mill or water hammer,then use the high pressure water jet to erode the formation and create a seepage channel with specified depth and bore diameter in the formation. The situation of geology and hydraulic fracturing of the ChangQing oil field was studied;the abrasive water jet perforation and hydraulic fracturing tool on the basis of the abrasive water jet perforation were designed. The oil well was handled by the integrated tool of the abrasive water jet perforation and hydraulic fracturing and a channel with high seepage capability was developed so as to save the operation time and reduce the product cost.
