| 摘 要： | 歧口凹陷奥陶系地层发育碳酸盐岩沉积,主要为泥晶灰岩、泥晶白云岩、岩溶角砾岩。综合岩相、沉积构造特征及测井相分析重新确定其沉积相类型为开阔台地、局限台地和蒸发台地,提高了对歧口凹陷奥陶系古岩溶发育情况的认识,为该区油气勘探预测有利区带提供了可靠依据。 |
| 关 键 词： | 奥陶系 沉积相 台地 歧口凹陷 |

| Abstract: | Carbonate rock consisting of micritic limestone,micritic dolomite and karst breccias was developed in the Ordovician in the Qikou Depression.The petrographic characteristics,sedimentary structural features and logging data indicate that it was deposited on an open platform or restricted platform and evaporation platform.This is of importance to oil and gas exploration in the depression. |
| Keywords: | Qikou depression Ordovician sedimentary facies open platform restricted platform |
