油气化探的△C法已经成功地应用了46年之久。碳同位素比值以及痕量金属分析与此法的结合,则是在较近时期才出现的,这就为油气化探增添了一项新的内容。本文要评述这三种方法的基本原理,并介绍它们在得克萨斯州一个正在开采的油田上成功应用的实例。由近地表土壤采样提供的△C,碳同位素及痕量金属数据结合起来分析,是综合运用油气化探技术的一个重要步骤。基本原理简单地说,油气化探的所有方法是建立在很多有争议的认识基础上的,这些认识 The oil and gas geochemical method △ C has been successfully applied for 46 years. The combination of carbon isotope ratio and trace metal analysis with this method occurred only in a relatively recent period, which added a new dimension to oil and gas exploration. This article reviews the rationale for these three approaches and describes their successful application in a field that is being mined in Texas. The analysis of △ C, carbon isotope and trace metal data provided by near-surface soil sampling is an important step in the comprehensive utilization of oil and gas geochemical exploration. Rationale Simply put, all methods of geochemical exploration are based on many controversial understandings that
