Remaining Oil Comprehensive Evaluation And Tapping Potential Method Of Xing 12 Block In Daqing Oil Field

Daqing Oil fields has been developed for many yeas,and for the most part has experienced well pattern thickening and pattern modification for many times, and in part areas has developed by injecting water,polymer and chemical flooding,now many oil fields come into high-cut stage, the distribution of remaining oil is very scattered and developing is too difficult,in order to exploit this part oil we have do many scientific research,and have accumulated some experience and basic approach,all this is helpful for the same kind oil field's exploitation.In this paper it based on a specific test area, developed a research for the character of remaining oil and exploit method, integrate the specific problems of complexity series of development strata and bushing damage and pressure imbalance.the study include structural reservoir and fluids property,refinement and verifying the reservoir character,the study provided many reliable theoretical principle for snalysis reservoir develop state and remaining oil character accurately.In study of remaining oil distribution we used the technic of water flooding explain,intake profile analysis,core analysis and oil fields simulation,Base on the analytic result of comprehensive technic and contrapose the different kind remaining oil designed corresponding aggregate adjustment.By now the executed aggregate adjustment has yield a excellent prophase result,all these analytic technique will be helpful for the high-cut stage remaining oil exploitation of the same stype oil field.
