Abstract:Mast helium result from the combination of one a particle released by decaying radioactive element with two electrons, polonium is the decay daughter of radioactive element radon. The geochemical properties of helium and radon show that they can accumulate in hydrocarbon reservoir and easy migrate upward from the hydrocarbon reservoir to the surface. They usually farm circular distribution zones over oii-gas. field because of secondary change over the field. The real determinations of helium and polonium elements show their good surface circular distribution zones, which generally correspond to the extents of oil-gas field. Therefore, the determinations of the two elements will have wide application prespects in oil and gas reconnaissace.
