Application of optimized perforation design in jilin oilfield

Abstract

According to the conditions of the bad reservoir physics character of Juin Yingtuo oilfield, all the new perforated and completed wells must being hydrafrac to increase production and some bottom hole water of them having developed much, producing water after hydrafrac and high exploitation expense, hang composite perforation tech is utilized to be well completion to increase production and effect. It is confirmed that the composite perforation tech fits for the new wells putting into production in Taobao oilfield. To actual situation of Taobao oilfield and using 102gun and BH64RDX-2 bullet, positively and reversely spiral perforation, the best bomb altitude and penetrating depth are achieved which enhances the leak-off area of oil layers to increase the output of oil well accordingly.
