酸解烃、水溶烃、热释烃等地球化学勘探方法中，样品预处理工作是必不可缺的环节，但是目前我国化探样品预处理装备技术仍然停留在30年前建立的手工化学处理阶段，与当前高精度分析仪器普遍应用的现状极不匹配。笔者基于自主研发的智控型化探样品预处理系统，分别介绍了工作原理、控制结构、实现技术、性能指标及测试检验结果，并将该技术应用于国际大洋钻探ODP（Ocean Drilling Program）204航次岩芯样品酸解烃测试和我国南海北部海水水溶烃指标测试，验证了其在天然气水合物地球化学勘探中的效果。实践证明，该系统具有自动快速、精密安全、便携简洁的特点，促进了化探样品预处理技术装备的进步，在我国化探样品实验室预处理和野外现场工作中具有广泛的应用前景。

In many kinds of geochemical exploration methods such as acidolysis hydrocarbon, dissolved hydrocarbon and thermally re?leased hydrocarbon, the geochemical pretreatment of the sample is very important. Nevertheless, China?s sample retreatment technique remains at the stage of manual operation, which does not match the widely used high?precision analytical instruments. On the basis of researches on the intelligent?control geochemical sample pretreatment system, this paper deals with in detail the working mechanism, control structures, implementation methods, performance indexes and quality inspection results of this system, and describes the appli?cation achievements in gas hydrate exploration with acidolysis hydrocarbon methods in ODP204 and dissolved hydrocarbon methods in Dongsha area, the South China Sea. Practices have proved that the intelligent?control system is capable of completing the geochemical sample pretreatment work under the automatic condition, and has properties of fastness, precision, safety and portableness. It has promising application prospect in China?s marine gas hydrates exploration and terrestrial petroleum geochemical exploration, and also has great significance for improving China?s geochemical sample pretreatment equipment techniques.
