Development technology and application of heavy oil thermal recovery in Bohai oilfield
After more than ten years of exploration,Bohai oilfield has made significant breakthroughs in key technology research and equipment construction,exploring a successful path suitable for offshore heavy oil thermal recovery.This study involves seven heavy oil thermal recovery oilfields in Bohai oilfield,with 67 wells undergoing steam stimulation and one steam drive test well group.Through 97 well heat injection parameter statistics and de-velopment and production performance analysis,it was found that only six well steam stimu-lation processes were smooth,exposing 12 problems in heat injection,thermal recovery,and geological reservoir research.There were a total of 167 well events during the steam stimula-tion process that seriously affected production.And pointed out the corresponding technical measures for pre-treatment before heat injection,such as increasing oil well injection,water pressure in oil layers,preventing gas channeling,and increasing reservoir energy,hoping to attract high attention and better and efficiently develop offshore heavy oil.
