油气藏的流体类型是勘探和开发决策的关键，随着渤中构造勘探评价的深入，复杂砂砾岩储层油气藏流体类型的识别显得越来越困难。在前人研究的基础上，以渤中构造孔店组复杂砂砾岩储层油气藏为研究目标，依据研究区典型井流体组分分析结果为基础，利用相态分析判别法和烃组成组合参数经验判别法等方法，对渤中构造孔店组复杂砂砾岩储层油气藏流体类型进行综合识别。结果表明，相态分析判别法和烃组成组合参数经验判别法结论一致，该组合方法应用效果良好，渤中构造孔店组复杂砂砾岩储层油气藏以无油环凝析气藏为主。

Reservoir fluid type is the key to the exploration and development decision making.With the deepening of the BZ structure exploration evaluation, the identification of fluid types of complex glutenite reservoir is becoming more and more challenging.On the basis of previous studies, taking the complex glutenite reservoir in Kongdian Formation of the BZ structure as the research objective, based on the analytical results of fluid components in typical wells in the study area, the phase analysis method and the hydrocarbon-composition-parameters based empirical determination method are used to identify the fluid types of complex glutenite reservoir in the Kongdian Formation of the BZ structure.The results of two methods are highly consistent.The combined method has a good application performance.The complex glutenite reservoir in the Kongdian Formation of the BZ structure is dominated by oil-free condensate gas reservoir.
