Analysis and Research on Low Damage,Temperature Resistant,and Long acting Completion Fluids for M Oilfield in the Eastern South China Sea
In response to the problem that the M oilfield in the eastern South China Sea can only be put into production after more than 8 months of completion,and that long-term retention of completion fluid in the reservoir may cause serious reservoir damage,this study investigates the types of reservoir damage caused by completion fluid and the types of low damage completion fluids,analyzes the development trend of low damage completion fluids,and summarizes the methods of selecting well performing completion fluid systems for on-site application;Analyze the potential damage factors of high-temperature and long-term static storage of completion fluids in reservoirs,and propose targeted methods to improve the long-term temperature resistance performance of completion fluids.By conducting research on the current status of low damage completion fluids and analyzing the impact of high temperature and long-term performance of completion fluids,this provides certain guidance for the construction of a low damage,temperature resistant and long-term completion fluid system in M oilfield.
