石油地质分析测试技术新进展

近年来,新的分析测试技术在石油地质研究及勘探活动中取得了很大进步.尤其是含油气地层的流体包裹体研究更是突飞猛进,它能测定地质历史上的时代变迁和物理化学条件.轻烃分析方法也取得了很大进展,特别对源岩.烷基酚和苯并咔唑抽提法也获得成功,借助苯并咔唑的浓度及比值变化可以研究油气运移.此外,包括伊-蒙混层、伊利石在内的粘土矿物分析方法也发展迅速.例如,伊利石的结晶度值被广泛地用于松潘地区的石油地质勘探. 

NEW TECHNOLOGICAL ADVANCES IN PETROLEUM EXPLORATION

New analytic technologies in petroleum geological research and exploration activities have made great progress in recent years. Especially there has been a burst in the fluid inclusion study of oil-bearing sequences, which can determine the timing and physical-chemical conditions in the past. Light hydrocarbon analytic methods is making much progress, especially in source rocks. The alkylphenol and benzocarbazole extraction methods are also successful, and the changes in benzocarbazole concentration and the ratio of benzocarbazole can be used to discuss hydrocarbon migration. Also, the analytic method of clay minerals including mixed layer I/S, illite, etc. has developed fast. For example, the crystallinity values of illite are wildly used in the petroleum geological exploration of Songpan region.
