| 摘 要： | 柴达木盆地干柴沟地区在不同湖盆演化阶段发育了两种不同类型的扇三角洲沉积体系－－退积型与高位填积型。这两种扇三角洲沉积体系形成于特定的地质背景之下，具有不同的成因相构成型式和储集性能，其中退积型扇三角洲沉积体系前缘、水下分流河道砂体、河口坝砂体、近岸重力流砂砾岩体、远源浊流砂体储集性能良好，易于形成油气圈闭。 |
| 关 键 词： | 柴达木盆地 干柴沟 第三纪 扇三角洲 成因 含油气性 |

| Abstract: | There are two types of fan-delta sedimentary systems-retrogradation type and perch aggradation type that are developed at different lake evolvement in Ganchaigou area of the Qaidam basin.The two systems formed under special geologic background have different composite shapes of genetic facies and reservoir capabilities in which the sand body in underwater distributary channel and mouth bar,the sand-conglomerate body forming in down-coastal gravi-ty flow deposit,the sand body forming in distal turbidite deposit at the delta front of the retrogrative fan-delta have better capability of reservoir and easily form hydrocarbon traps. |
| Keywords: | Qaidam basin Ganchaigou Tertiary fan delta genesis hydrocarbon-bearing property |
