| 摘 要： | 通过岩相标志、测井相标志对泌阳凹陷的核三段进行了详细研究。核三段沉积相的展布揭示了泌阳凹陷在核三段时期发育的沉积相类型(扇三角洲、辫状河三角洲、湖泊相及它们的微相);核三上段湖区发育大面积的白云岩;泌阳凹陷核三段为一淡化期和咸化期相互交替的常年性盐湖沉积,总体上盐湖经历了由深到浅再到深和由淡到咸再到淡的演化过程。

| Abstract: | The paper studied detaily the sedimentary facies of the 3rd member of Hetaoyuan formation(H_3) in Biyang depression, using the petrographic signs,and signs of elextro - facies; It also revealed the sedimentary facies' types(fan- delta, braided river delta,lacustrine facies and their micro- facies) of the H_3 in Biyang depression;there are large areas of reservoirs which developed in the upper of the H_3;the H_3 in Biyang depression is perennial salt lake deposits alternating with dilute phase and salinizati... |
