摘要
川西龙门山前雷口坡组处于山前隐伏构造带,储层属于海侵期的以局限台地潮坪相为主的沉积特征,储层宏观上发育微-粉晶白云岩、藻白云岩储层,微观上以白云岩孔隙型和白云岩裂缝-孔隙型为主的中孔特低渗储层。详细的研究对川西龙门山前带雷四气藏勘探突破与提交千亿方储量整装气田具有重要的指导意义。
the Leikoupo formation in Longmen Mountain in western Sichuan is located in the hidden structural belt in front of the mountain,and the reservoir belongs to the sedimentary characteristics of the limited platform tidal flat phase during the transgression period.The reservoir develops micro-powdery dolomite,algae dolomite reservoir,and mesoporous ultra-low permeability reservoir dominated by dolomite pore type and dolomite fracture-pore type.The detailed study has important guiding significance for the exploration breakthrough of Lei Si gas reservoir in Longmen Mountain front of western Sichuan and the submission of 100 billion square reserves packed gas field.
