| 摘 要： | 致密含气砂岩储层的特点是孔隙度小、渗透率低、含气饱和度高,使用常规测井方法很难求准储层的地质参数,如孔隙度、渗透率.核磁共振测井可以准确地提供地层的自由流体体积和束缚流体体积、有效孔隙度及其渗透率,能较好地判断干层、水层及气层.

| Abstract: | It is very difficult to calculate the geological parameters of tight gas-bearing sandstone reservoir which has low porosity, low permeability and high gas saturation by using conventional logging technologies. NMR Logging can provide accurate values of irreducible liquid, movable liquid, effective porosity and permeability, and also identify the tight zone, water zone and gas-bearing zone. |

| Keywords: | tight gas-bearing sandstone NMR logging effective porosity permeability reservoir evaluation |
