| 摘 要： | 深部地层的裂缝按产状可分4类。岩心裂缝充填物组合染?如电子探针元素测定分析证明了下白垩统泉头组(K_1q)和登娄库组(K_1d)中发育的成岩裂缝中充填方解石为无铁方解石。侏罗系地层的构造剪切缝中充填富铁方解石。氧、碳同位素的测定进一步证实了下白垩统和侏罗系地层中两套裂缝的不同成因和不同形成阶段以及它们同油气演化的关系。

| Abstract: | Four types of fractures are recognized in deep formations. The results of staining and element measuring by micro-probe indicate that the calcite filling in diagenetic fractures of K_1q and K_1d are nonferro-calcite and the ferro-calcite arefound in J structural fractures. Two fracture systems of different origin and developing in different geological stages arealso proved by oxygen and carbon isotope data. The comments on the relationship between fractures and hydrocarbonevolution are presented. |
