| 摘 要： | 盆地或地区的油气地质条件是形成油气地球化学场特征的物质基础，构造运动是烃类离开油气源区，向储集层运移和纵向运移的主要动力，而近地表沉积物性质和地形地貌景观条件是影响油气化探效果的重要因素。若尔盖地区的弧形构造对化探指标浓度的空间分布的影响作用，表明地质构造对近地表地球化学场的分布有明显的控制作用。

| Abstract: | The oil-gas geological conditions of a basin or an area constitute the material basis for the formation of oil-gas geochemical field, the structural movement is the main force causing the migration of hydrocarbons from the oil-gas source area to the accumulation reservoir or the longitudinal migration of hydrocarbons, and the near-surface sediments and landform and landscape conditions make up important factors affecting the effects of oil-gas geochemical exploration. The influence of the arcuate stnacture in Zoige area on the spatial distribution of the geochemical index concentration shows that geological structures obviously control the distribution of the near - surface geochemical fields. |
