超低渗透油藏核磁共振可动流体研究--以鄂尔多斯盆地西南部长8储层为例
Research on movable fluids in ultra-low permeability reservoir with NMR technology：An example from southwest chang 8 reservoir in Ordos Basin
摘要
Abstract
The sandstone samples of the ultra‐low permeability reservoir in southwest chang 8 of Ordos Basin were tested with the nuclear magnetic resonance technique .The results show that the ultra‐low permeability sandstone T2 ,cutoff value distributes between 3 .96~23 .14 ms .The content of movable fluid is high ,and the parameter of movable fluid is expanse .The movable fluids of ultra‐low permeability and low permeability sandstone are distinct in holes of different sizes ,and the ultra‐low permeability sandstone movable fluid distributes in 0 .1~0 .5 μm .The conversion law of movable fluid percentage and permeability in holes of differ‐ent sizes is converse ,because the relative size of capillary dialysis and flooding is different . And the 0 .5 × 10 -3 μm2 is defined as the lower permeability limit of water flooding in south‐west chang 8 of Ordos Basin .关键词
