Thickness is an important parameter in evaluating caprock. There is not direct relation between thickness and seal abilities of caprock,but it controls each seal ability of caprock in fixed degreen. There is direct proportion relation between thickness and capillary seal ability of caprock or pressure seal ability of caprock, or concentration seal ability of caprock. This paper discussed the relation between thickness and each seal ability of caprock from theory and actual data in oil or gas field.
