利用土壤中烃类含量和其他有关化学组分等化探方法寻找油气藏的试验,已有五十多年历史。但由于土壤是岩石圈、水圈、大气圈和生物圈互相进行化学和生物作用的产物,影响因素复杂,没有获得大的突破。前不久,美国达拉斯化探公司发表了经过多年探索所总结的△C地球化学晕法,该法的实质是:如下图所示,当油气藏中的藏中的气体和低分子烃类,
More than 50 years have passed since the discovery of hydrocarbon reservoirs using hydrocarbon content in soil and other chemical methods such as chemical composition. However, due to the soil is the product of chemical and biological interaction between lithosphere, hydrosphere, atmosphere and biosphere, the influencing factors are complex and no major breakthrough has been achieved. Not long ago, the United States Dallas Geochemical Exploration Company published after many years of exploration summarized △ C geochemical halo method, the essence of the law is: As shown below, when the reservoir of Tibetan gas and low molecular hydrocarbons,
