This paper introduces the development course and current state of perforation technique in Daqing oilfield,including perforating depth control,high efficiency perforation technique,perforation mechanism and optimization,and presents that the cur鄄 rent perforation technique has attained the advanced level in China by realizing deep penetration,large aperture, high density pattern,directionfinding,low damage and digitization. The50 yearspractice of perforationtechnique also proves that overall improvement and comprehensive perfection of perforation technique can ensure the realiza鄄 tion of objectivesinexplorationanddevelopment,improvetheeffectandmeet specificrequirements,whichprovide a foundation for the development and optimization of perforation technique.
