塔中Ⅰ号断裂带中、上奥陶统 (Ｏ2 + 3 )石灰岩裂缝发育期次问题 ,是一个久未解决的难题。笔者依据 11口井岩心裂缝观察的结果 ,结合充填于裂缝中的方解石流体包裹体测定和岩石凯塞效应 (Ｋａｉｓｅｒｅｆｆｅｃｔ)测试结果等对此进行了研究。裂缝充填情况和切割关系 我们知
In the Tazhong Ⅰ fault zone, the sub-grade problems of the Upper Ordovician limestone fractures are an unsolved problem. The author based on the results of the observation of core fissures in 11 wells, combined with the determination of fluid inclusions of calcite filled in fractures and the Kaisereffect test results of rocks. Crack filling and cutting relations we know
