油气化探中土壤碘测量技术应用研究

APPLICATION OF SOIL IODINE CONTENT MEASUREMENT IN THE OIL AND GAS GEOCHEMICAL EXPLORATION

地表土壤碘用于油气勘探的主要依据是:在地表可以获得足够光源的情况下,碘元素可替代轻烃分子中的一个或多个氢原子从而形成比较稳定的有机碘化物。地表土壤碘异常具有两种典型的异常模式——顶部高值异常与环晕状异常。根据土壤碘异常模式的形成原因,认为未开采远景区土壤碘高值异常可用于筛选有利含油气区带,详查时还可用于预测油气藏的分布范围;已采区的碘浓度高值异常,则可指示已知油气藏的扩展区。文中以实例阐述了这一认识。地表土壤碘指标的油气勘探意义在于,当与其他勘探方法结合应用时,它可从另一视角为油气勘探决策提供依据。

The surface soil of iodine for the main basis for oil and gas exploration is： get enough light on the surface, the iodine can substitute for light hydrocarbon sub-elements Son of one or more hydrogen atoms to form the relatively stable organic iodide. Abnormal iodine soil surface with two typical abnormal pattern - Top Department of high-value anomaly and abnormal ring-shaped halo. Iodine according to the soil causes the formation of abnormal patterns that are not long-term exploitation of soil iodine can be used for high-value anomaly screening Favorable oil and gas zone, detailed investigation may also be used to predict when the distribution of oil and gas reservoirs; mining area has high concentrations of iodine value of abnormal, he may direct the known oil and gas reservoirs The extension area. Examples in the text elaborated on this understanding. Indicators of surface soil iodine is about oil and gas exploration, when combined with other exploration methods applied , It can be from a different perspective to the oil and gas exploration and provide a basis for decisionmaking.
