Study Of The Chaoyanggou OilField's Classify Fathering And Exploitation

Chaoyanggou oilfield is the biggest low permeable of daqing oilfield,as limite by lithology,sedimentarymicro-facies,faults, oil-water relation is complex.With the developing time, the oilfield gone worse.this document is focuses on how to Classify Fathering and improving the development effect of the oilfield base on studies of many civil and abroad,as follows:First,base on Chaoyanggou oilfield character of geology and development, summarize the fundamental states of three areas, providing fundamental principle of Classify Fathering of Chaoyanggou.Second,Clear distribution of remaining oil and point out regulation, increasing method.By profile control deep experiment, waterfloof injection well change to oil well ,microbial oil recovery and so on to Classify Fathering areas one.Third,make improving study of Economic Limits for enhancing wellnet density and optimize enhancd wellnet density waterfloof injection structure.on the basis of them, reinforce enhancing wellnet density potential study,make areas two Classify Fathering better.Forth, make improving study of reservoir, increase of waterfloof injection utilization ratio, make research on oil recovery by heat and so on, make areasthree Classify Fathering better.By Classify Fathering, Exploitation effects of Chaoyanggou oil field have been availably improved, Oil output reduce slower and moisture percentage increase slower significant socioeconomic benefit has been obtained. and significant socioeconomic benefit has been obtained.
