| 摘 要： | 白云岩以其次生晶间孔隙发育、易于形成高孔高渗优质油气储层为特征,长期以来受到地质学界的高度重视.早期白云石晶体自形程度及晶间孔隙的发育程度除受白云石化成岩流体的影响外,还受原岩储渗性能的控制.川东北宣汉-达县地区飞仙关组白云岩主要存在渗透回流白云石化、混合水白云石化和埋藏白云石化3种成因模式和至少3期次云化.白云岩化并...

| Abstract: | The dolomites are characterized by the developed secondary intercrystalline pores and easily form qualified reservoirs with high permeability and porosity,and thus are emphasized by geological academic circles for a long time.The idiomorphic degrees of dolomite crystals and the developing degrees of intercyrstalline pores are controlled by accumulating and permeable properties of the original rocks in addition to fluids leading to dolomitization.There exist three genetic models of dolomitization,such as the... |
