补充资料：油气化探
| 油气化探 oil and gas，geochemical prospecting for 以石油和天然气为主要寻找对象的地球化学勘查方法。原生油气在运移和聚集过程中遗留下来的痕迹和生产的影响，使周围的土壤、岩石和地下水等介质中的组分发生显著的变化，造成局部地球化学异常，成为寻找油气的信息。这是油气化探的依据。油气化探是一种多指标的综合测量方法，其中比较重要的有4种：①气体测量方法。包括烃气或酸解烃测量、汞气或热释汞测量和氦气测量等。②土壤碳酸盐法。其中的ΔC法，只测定在干扰最少的指定温度区间内热解释放出的二氧化碳。同时，再利用碳同位素（δ13C）法和微量元素测量配合，提高异常的可靠性。③水地球化学法。主要通过采集水样，进行常规水化学指标分析以及水中溶解烃、脂肪酸与环烷酸、苯、酚和微量元素等含量的分析来发现异常。④荧光测量法。采集土壤样品，测量残留其中的液态或固态的高分子重烃。它们往往与下伏油层有关，并具有与石油相近的荧光光谱。 |
