Water－cut Rising Regular Pattern in Reservoirs with Different Permeability in Shuanghe Oilfield and Production Potential Tapping

Reservoir pore structure and physical properties are the essential elements that have an impace on rising rate of water－cut and development effect． The reservoirs in Shuanghe oilfield are divided into 4 types according to permeabilty pore structure and rock type． This paper studies water－cut increasing pattempresents production potential tapping procedures in the Ⅲ and Ⅳ types of reservoir unit． Field application shows that the production potential tapping effect are remarkable．
