| 摘 要： | 通过岩心和薄片观察,普光气田飞仙关组飞一到飞三段并不发育石膏,储层中H2S溶蚀作用的标志也不多见,相对于H2S,鲕滩储层的发育与其原岩鲕粒灰岩关系更密切。鲕粒灰岩本身发育原生粒间孔,经大气水溶蚀后也可以形成较好的储层,是普光气田鲕滩储层形成的物质基础。飞仙关期鲕滩的加积作用、飞仙关组早期快速埋藏和烃类充注的匹配、飞仙关组的构造托举和上覆雷口坡和嘉陵江组的膏盐悬浮减压,构成了原生粒间孔、同生期溶孔和晶间孔的保存成因。早期孔隙网络的发育和良好的保存成因,为后期埋藏溶蚀流体的出入提供了良好的条件,最终演化成了优质储层。

| Abstract: | The drill core and thin slice observation show that there are no gysum and little marks of H2S corrosion in oolitic beach reservoir.The development of oolitic beach reservoir has no obvious relationship with H2S, but has close relationship with oolitic limestone.The oolitic limestones develop primary intergranular pore, generate preferable reservoir on conditions of corrosion by meteorological water, and it is the material base of oolitic beach reservoir in Puguang Gas Field.The oolitic beach aggradation, t... |
