This paper reviews the current techniques on completion in Daqing oilfield.The three series of completion techniques(conventional perforation,TCP and new completion) are formed including fourteen technologies,which are adaptable to different geologic settings and hole conditions.There are 7 conventional well completions,that are wire-line conveyed perforation,tubing-conveyed perforation,horizontal well perforation,overbalanced perforation,orientation perforation,pressured operation wire-line conveyed perforation and full bore tubing-conveyed perforation.There are 5 joint operation well completions,that are the joint of tubing-conveyed perforation and testing,the joint of perforation and pumping,the joint of perforation and fracturing,the joint of perforation and high energy gas fracture,the joint of perforation and acidizing.There are 2 new well completions,that are hydraulic sand jet perforation and hydraulic slotted liner technique.The technology is content with the need of different development pattern completions.The field application results on different completion techniques in Daqing peripheral oilfield are analysed.The completion techniques level and problems are outlined and the prospects are pointed out.
