Title: Potential analysis and potential tapping direction of the remained reserves in Lasaxing oilfields
Abstract: A new method to calculate OOIP of each kind of oil well is established by means of integrating waterflood characteristic curve and relative permeability curve.At the same time,the above reserves in each kind of oil well have been calculated.By combination of dynamic and static data,the distributary feature of remained reserves in Lasaxing oilfields has been analyzed, and further adjusting and tapping directions have been made clear.The development situation of remained recoverable reserves proportion, water cut,oil production rate and so on controlled by waterflood classified wells in Lasaxing oilfields is studied, and then the current existing main problem and contradiction during oilfield development are analyzed. In the light of the reality of nearly same water cut in these wells,the follow conclusion is drawn:under the condition of meeting a certain oil production requirement,when fluid production proportion of the above wells is near to their OOIP proportion, the effect of water control is the best.With the help of this conclusion,development pattern adjustment and structure optimization of waterflood classified wells in Lasaxing oilfields have been studied.
