试论岩石组构与油气成藏及驱采效果的关系

Trial discussion on the relationship among rock fabric and oil gas reservoir forming, displacement recovery effect.

总结了与岩石组构相关联的欠压实泥岩与高孔隙度、高渗透性砂岩 ,同盆深湖泥岩与滨岸粒屑滩 ,烃源岩与刺穿岩体 ,以及构造与岩性等 4种组合的成藏规律。通过开发现场的实例分析 ,论述了岩石组构对油气产出率的影响。该项研究首次将分析岩石微观组构特征运用于油气成藏规律识别和增产改造开发设计中。

Reservoir forming rules of four assemblages related to rock fabric are summed up, they are undercompaction shale and highporositypermeability sandstone, deep lake mudstone and shoreside grain beach in the same basin, source rock and piercement rock body, structure and lithology. The influence of the rock fabric on the oilandgas production rate is discussed by the analyses of the field cases in the production. Analyses of microfabric features of rocks are applied to identification of oilgas reservoir forming rules and development design of stimulation and reformation.
