| 摘 要： | 气体地球化学在寻找矿藏和隐伏断裂中已经得到广泛应用,针对不同的土壤条件,如何采集合格的壤中气样品,是气体地球化学方法取得成功的关键因素之一。国内外不同类型的壤中气采集器,每一种只能适应一种特定的土壤环境,而对于潮湿黏土,易于积水的土壤层,缺少有效的办法。最新发明的"地气采集螺旋钻"可以解决此问题,易于采集到合格的壤中气样品。不同类型的已知油气藏上方的应用事例说明,利用壤中气进行烃类分析,可以有效地预测下伏油气藏。

| Abstract: | Gas geochemistry has been widely used in search for ore deposits and concealed faults. The collection of qualified soil gas samples suitable for different soil conditions constitutes one of the key factors for the success of the gas geochemical method. Every soil gas collector used in China and abroad can only be suitable for a specific soil environment. Effective methods are lacking for wet clay and soil layers likely to accumulate water. The "soil gas collection twist drill" invented by the authors can solve this problem. With this drill, we can easily collect qualified soil gas samples. Case studies over different types of oil and gas accumulations show that the utilization of soil gas to hydrocarbon analysis can effectively predict underlying oil and gas accumulations. |
