Research on evaluation about measures with water plugging in the west of Bei 3 area of Daqing Saertu oilfield

Measure of plugging water refers to through sealing high water formation to slow down the contradiction between lays, so as to increase the liquid production of low water formation and to increase the swept volume the extent of reserves producing. It is an important measure that aims at the rapid increasing of liquid-oil ratio in late stage of high water-cut, to keep the stable production of oil field. It is an effective measure to reduce and control the useless water production rate which not only can increase the fluid production sensibly but also can slow down the production decline and guarantee the economic rationality in oilfield development. Field practice has proved that the measure of plugging water has a better guiding significance to the reservoir in late high or extra high water-cut stage. Through analyzing the effect of plugging water, and a comprehensive evaluation of the effect of plugging water, we can find out the key factors that affect the measures of plugging water, which has a better guiding significance to maximize the high water cut oilfield development profit.
