Advanced water injection in low permeability reservoir of The wuqi oilfield

In accordance with the features of low permeability,low abundance,fast declining,difficult to stabilize production,and low recovery factor,advanced water injection has been conducted in block wu93 of The wuqi oilfield.Based on the study in the reservoir,this paper elaborates the measures of advanced water injection in aspects of the opportunity of water injection,the effective time of Water Injection,the proper pressure of water injection,the proper intensity of advanced water injection.This method has obtained an evident effect in the oil field production.The advanced water injection can enhance the level of developing low permeability reservoirs.The success of advanced injection development test may guide the development of similar oilfields or blocks.
