压汞曲线在确定JZS油田潜山储集类型中的应用

Application of capillary pressure curve in buried hill reservoir type classification of JZS oilfield

通过调研,结合JZS油田变质岩潜山储层特点,提出了JZS油田潜山储集类型划分标准。根据压汞曲线反映的储集空间渗流特点,并通过计算,确定JZS油田潜山储集类型为孔隙-裂缝型。应用表明,该方法简便可靠,能为油田开发井型选取和井网部署提供依据。

Through investigation and research,combined with metamorphic buried hill oil reservoir characteristics of JZS oilfield,buried hill reservoir type classification has been proposed.According to the percolation characteristics of reservoir space reflected by the capillary pressure curve,and through calculation,the buried hill reservoir type of JZS oilfield has been determined,namely pore-fractured type.The application results show the method is simple and reliable,and it can provide guidance for field development well choose and for well pattern deployment.
