Evaluation of development effect and study on remaining oil production potential of Jurassic reservoir
Taking Y10 reservoir in area H as an example,this paper evaluates the develop-ment effect from three aspects,formation energy,water drive status and oil recovery factor.The distribution of remaining oil is studied by numerical simulation,the infill adjustment well location is precisely deployed and the adjustment effect is predicted,field test is carried out and the infill adjustment potential is analyzed.The results show that the study area is af-fected by the development of high production fluid strength and wellbore casing breakage,the effect of water flooding is worse,recovery degree is lower,and the remaining oil is en-riched locally in the study area.Numerical simulation predicts that the adjustment of reser-voir infill can effectively improve the ultimate oil recovery.The field test shows that the infill adjustment has good effect and practicability,which can further expand the infill adjustment range and enhance oilfield recovery efficiency.
