| Abstract: | The cause of insufficient injection and remedial measures for injectors in Chang8 oil reservoir of M oilfield in northern Shaanxi was studied by analyzing rock characteristics, reservoir physical properties, the compatibility of injection water and formation water,wellbore and water injection system. It is of great significance to reasonable measures of drawdown and augmented injection and long-term stable and efficient development of the reservoir.This shall provide references for similiar reservoir management in the future.This shall provide references for similiar reservoir management in the future. |
