Application of Abrasive Water Jet Perforation Assisting Fracturing

摘要

This article presents a new technology of abrasive water jet perforation assisting fracturing on Well Zheng 408-8,Bin Nan Production Plant,Shengli Oilfield.First,the balsting tool,with 9 nozzles,was lowered down to the payzone and perforated 90 tunnels with abrasive water jet after being moved upward 9 times.Then the fracture work was conducted and 18 m3 sands were squeezed into the formations.After that the well production reached 11.6 t/d liquid and 8.7 t/d oil,respectively,and this continued for 9 months.But before the job,nothing was produced from this well.
