地面地球化学勘探方法,经历了数十年的反复试验、研究,日趋成熟,成效显著。在当今油气勘探成本升高、油价下跌、紧缩勘探费用之机,重视和支持价廉的地球化学勘探方法具有重要意义。地球化探方法中,土壤盐类△C值法、新气测法及氦气检测,灵敏度高、精度可靠,是行之有效的新方法。 Ground geochemical exploration methods, after decades of repeated testing, research, maturing, with remarkable results. In today’s oil and gas exploration costs, lower oil prices, tightening exploration costs of the machine, attention and support of inexpensive geochemical exploration methods of great significance. Geochemical exploration method, the soil salt △ C value method, the new gas detection and helium detection, high sensitivity, accuracy and reliable, is a new effective method.
