普光气田飞仙关组和长兴组为台地边缘生物礁和鲕粒滩相沉积,储层岩石类型以白云岩和灰岩为主,白云岩储层发育。储集空间以溶蚀孔洞为主,局部发育裂缝。孔洞和裂缝发育不均匀导致孔隙结构比较复杂,孔渗关系变化多样。通过岩电关系对
Feixianguan Formation and Changxing Formation in Puguang Gas Field are reef-rimmed and oolitic beach facies sediments. The reservoir rock types are dominated by dolomite and limestone and dolomite reservoirs are developed. The reservoir space is dominated by dissolution holes and local development cracks. Uneven development of pores and cracks leads to complicated pore structure and varied pore-permeability relations. Through the relationship between rock electricity
