摘要
根据野外剖面及钻井岩心的宏观观察, 借助薄片和物性资料对宜宾潜伏构造T1 j14 —T1 j3 段储层特征、控制因素进行了研究。研究表明, 宜宾潜伏构造T1樀─3csub>14─3c/sup>—T1樀─3csub>3段储集岩储集性能白云岩最好, 储集空间主要有晶间孔、晶间溶孔和裂缝。影响储层特征的主要成岩作
用有白云岩化作用和古岩溶, 总的来说, 宜宾潜伏构造储层为低孔、低渗储层。
Abstract
Th is paper is based on the outdoo r pro file and the
m acroscop ic observation of dr illing core. W e research on the
reservo ir character istics and contro lling factors of Y ibin bur ied
structure T1 j3 ~ T1 j4
1 reservo ir w ith draw suppo rt from lam ella
and physica l property datum. The result indicates that the
best reservo ir rock o f Y ibin bur ied structure T1 j3 ~ T1 j4
reservo ir is do lom ite. Reservo ir space m ainly inc ludes
intercrysta l pore, intercrysta l so lution po re and split. The
m a in diagenesis affecting the reservo ir character istics is
do lom itization and palaeokarst. In genera ,l Y ib in bur ied
structure is featured by low porosity, low perm eab ility based
on the com prehensive eva luation.
