摘要
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 structure 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.
