本文据阿17-7井油基泥浆取心的岩样分析数据,评价了蒙古林砾岩油层含水饱和度问题.火山角砾岩由于孔隙结构微细,物性差,含水饱和度高;砾状砂岩及砂砾岩物性好,含水饱和度低。相对含油饱和度高.
This paper evaluates the water saturation of conglomerate reservoirs in Mongolia based on the data of rock samples taken from wells 17-17 in oil-based muds.Vaccia breccias have high porosity due to fine pore structure, poor physical properties and high water saturation. Gravel sand and gravel Good petrophysical properties, low water saturation. Relative high oil saturation.
