Oil/gas geochemical prospecting is closely related to oil/gas remote sensing in exploration prinsiple, although they are two different techniques. Both of them are based upon the theory of hydrocarbon microseeping and supplemented to each other in oil/gas exploration. Surface geochemical anomalies coincide with remote sensing image anomalies in spatial distribution. The integration of the two makes evaluation of oil/gas indicating significance of anomalies more reliable and can raise oil/gas prospecting efficiency.
