摘要

通过对大天池构造石炭系黄龙组储层特征的研究,发现储集岩以白云岩为主,储集空间以溶孔和晶间孔为主,储集类型属裂缝-孔隙型。储层以Ⅱ、Ⅲ类储层为主,主要受古岩溶剥蚀和白云岩化作用控制。石炭系黄龙组有效储层一般发育在石炭系地层残厚较大的区域内,且两者呈正相关性。通过地震预测发现,大天池构造中-南段的观音桥一带石炭系黄龙组地层残厚较大,是石炭系黄龙组储层发育的有利区域,也是下一步勘探的重点。
Through comprehensive researches of Da tianchi stucture belt reservoir characteristics,we find that the C2hl pore spaces were dominated by corrosion pores and crystal-to-crystal pores,and the reservoir type was defined as fracture-ore type.The reservoirs were mainly belong to type Ⅱ、Ⅲ,The reservoir physical property were primarily dominated by corrosion and dolomization.C2hl available reservoir usually develops in the area where the C2hl layer is thick,and there is positive correlation between them.Through reservoir prediction,it indicate that the C2hl layer in Guan yinqiao area of Da tianchi stucture belt is thick.It is the favourable area of reservoir development,and also be the primary area for the further exploration.
