Abstract
A method and device for detecting mercury isotopes in an oil-gas source. The device includes at least one enrichment-absorption system for mercury in crude oil/hydrocarbon source rock, an enrichment-absorption system for mercury in natural gas and at least one secondary purification-enrichment system for mercury. The enrichment-absorption system for mercury in crude oil/hydrocarbon source rock includes three air-absorption bottles, a pyrolysis/cracking system, five impact samplers, and a vacuum pump, which are connected in series by pipe lines. The enrichment-absorption system for mercury in natural gas includes five impact samplers connected in series, wherein the first impact sampler is connected to the natural gas outlet from the natural gas well and the last impact sampler is connected to the cumulative gas flow meter.
