| 摘 要： | 水溶性天然气是一种非常规天然气，具有潜在的利用价值。根据气水比变化，利用测井资料和用含气泥质砂岩双孔隙度模型电导率关系表达式所推导的含气饱和度模型，定量处理含气饱和度后,结合对水溶性天然气层测试资料，综合分析了柴达木盆地三湖地区第四系水溶性天然气层的分类，初步将该区水溶性天然气层分为4类。通过静态法经济评价确定气水比大于20 m3/m3的水溶性天然气层,在现有经济技术条件下具有经济价值；同时结合对钻录井资料以及地震资料的系统分析，指出气水比大于5 m3/m3的高气水比水溶性天然气层的成藏除了受气源与储层条件控制外，主要受构造圈闭、缓坡带以及陡坡带的发育程度等地质条件的制约和影响。 |

| Abstract: | Water-dissolved gas is a kind of unconventional gas.To further analyze the economic value of water-dissolved gas in the Quaternary of the Sanhu of Chaidamu Basin,the authors preliminarily study the classification of water-dissolved gas according to the change of gas/water ratio and after quantitatively processing the gas-bearing saturation using the gas-bearing saturation model derived by conductivity expression in a gas-bearing shaly sandstone dual porosity model along with referencing practical test resul... |
| Keywords: | Water-dissolved gas Classification Economic evaluation Reservoir controlling factor Gas/water ratio |
