摘要
火山岩储层岩相划分对确定有利储层分布、进行储层预测至关重要。针对火山岩油气藏勘探需要,结合松辽盆地长岭断陷火山岩油气地质特征,对火山岩爆发相和溢流相的亚相及微相进行划分,将亚相划分为近火山口、火山斜坡和远火山口亚相,将微相划分为上部、中部和下部微相。新的火山岩储层岩相划分方案,反映了火山岩储层的分布发育特点,具有明显的预测功能,有利于火山岩油气藏勘探开发。
Volcanic reservoir lithofacies division is very important to determine favorable reservoir distribution and reservoir prediction. Aiming at volcanic rock reservoir exploration needs, combined with petroleum geological characteristics of volcanic in the Changling Fault Depression of the Songliao Basin, subfacies and microfacies of volcanic eruption and overflow facies were classified. The subfacies were divided into near crater, volcanic slope and far away from crater ones. The microfacies were divided into upper, middle and lower ones. New volcanic reservoir lithofacies division method reflects the characteristics of volcanic rock reservoir generation and distribution. It makes prediction effectively and is favorable for volcanic rock reservoir exploration.
