摘要

摘要: 依据烃类垂向运移理论和物质吸附作用原理,自行设计开发、研制了一套吸附烃脱气装置,建立了土壤吸附烃提取新技术和检测方法。脱气装置结构科学,操作方便,适用于野外现场处理;检测方法的各技术要素保证了烃类气体脱附充分,检测到的烃类组分齐全。研究认为,当前油气化探中常用的酸解烃法检测出的烃不能定义为"吸附烃",它的基本原理和烃类气体提取过程决定了其获取的不是吸附烃,因此原生烃的影响往往造成酸解烃构成的异常真假难辨,具有多解性,影响其应用效果。吸附烃法可以弥补目前常用的一些烃类检测法的不足,获取油气系统的动态信息,提高油气地球化学勘探的效果。

Abstract: A degassing apparatus has been developed based on vertical hydrocarbon migration theory and material adsorption principle,thus a new extraction and detection method of adsorption hydrocarbon gas has been established.The apparatus is scientifically structured and easy to operate.It is suitable to be used in in situ hydrocarbon analysis in the filed.The technical elements of this detection method ensure that the adsorption hydrocarbon gas can be degassed completely,so that the full hydrocarbon components can be detected by means of this method.It is regarded that the hydrocarbon gas extracted by acid extraction method,which is commonly used in the current oil and gas geochemical exploration practices,can not be defined as "adsorption hydrocarbon gas" because of the basic principle and extraction process of this method.Therefore,it is often difficult to distinguish anomalies of reservoir-sourced acid extraction hydrocarbon from those of in situ inherent hydrocarbon.The uncertainty of hydrocarbon sources influences the application effect of acid-extraction method.The newly developed adsorption method of hydrocarbon,with its ability to acquire the dynamic information of a given oil and gas system,can remedy the insufficiency of the commonly used hydrocarbon detecting method,and improve the effect of oil and gas geochemical exploration.
