Discussion on secondary development technology practice of heavy oil in Shuguang oilfield

At present,heavy oil in old area of Shuguang oilfield is characterized by high recovery degree,high stimulation rounds,low formation pressure and inefficient wells and has entered mid and late development period.Therefore,combined with the secondary development technology experiment of the existing heavy oil in old area,through reservoir adaptability analysis of secondary development technology,such as the horizontal well drilling,hotwater flooding and steam flooding,the summary analysis of the effect of parameters optimization research has been achieved,which makes a discussion on secondary development technologies for the next step.
