非常规储盖层地化特征分析——井中化探的三个实例

Analyse the Geochemical Characteristics of Unconventional Reservoir and Cover——Three Examples of Geochemical Expolation in Drill

本文运用井中化探的三个实例,对非常规的油气藏盖层和储集层的地化特征进行了分析。砾岩层在特定的地质条件下,可以成为油气藏的盖层。岩性油气藏的化探罐顶气分析指标往往具有假象,影响对储层油气性质的正确识别。裂缝发育的泥岩也可成为储集层。

This paper analyse the geochemical characteristics of unconventional reservoir and cover through three examples of geochemical exploration in drill.In the special geological condition,the conglomerate may become the cover of oil-gas accumulation.Sometimes,the light hydrocarbons in head space index of lithological oil-gas pool have gloss.The gloss affects exact distinguish of oil-gas pool characteristics.The cracky mudstone as well as may become reservoir.
