Petroleum Production Engineering Technology Research During The Development Adjustment Of The Upper Guantao Formation Reservoir In The Southern District Of Chengdao Oilfield

According to the development adjustment scheme of the Southern District of C hengdao Oilfield and the development effect of the main part of C hengdao O ilfield,we optimize the auxiliary technology in view of the present adaptability evalution,production mode is given priority to submersible pump.Pump type was preferred,apheresis process and pump design process parameters were designed.The improvement of sand control is studied.According to the current sand control process and achieved results,optimization and design of sand control technology is studied.Fracturing sand control,circulation pack sand control,open hole horizontal well sand control and precision filter sand sand control were preferred.The second is the study of the water injection process,Chengdao oilfield has entered high water cut period,It has been continuously updated injection process in recent years.Through the effect of water injection and water flooding index in recent years,water injection process is optimized.General co-injection column injection,measuring the integrated zonal injection,concentric dual layered water injection were optimized,and evaluated various water process adaptability in the Southern District of Chengdao.Finally,we optimized the means and methods of production testing technology.
