The Study of Reservoir Damage Mechanism during Perforated Completion in Ng of Gudong Oilfield

Zhang Guangwei(Geologic Research Department,Gudong Oil Production Plant,Shengli Oilfield Ltd.Co.,SINOPEC,Shandong 257237,P.R.China)  
The reservoir may be polluted and injured during the course of drilling cementing production repairing.The fluid such as drilling fluid repairing well fluid injected water will pollute the reservoir if they are not fit with the reservoir,so that the production of the oil well is low slowly.It is an important safeguarding of protect oil gas reservoir to strengthen the research of the fluid which is injected into the formation.Perforation completion is an important mothed that may come into a permeable passageway between the reservoir and the well bottom,it may increase the production on oil well and reduce the damage to the oil gas reservoir.Hence we must strengthen the research on perforating fluid,perforation technology,injury mechanism,perforation parameters to avoid or reduce the damage to the oil gas reservoir in the perforation process.
