| 摘 要： | 塔河油田中-下奥陶统缝洞型储层是加里东中期-海西早期多次构造运动引起的多期岩溶作用叠加改造的结果。结合地质、地球物理和地球化学等分析方法,论述了塔河油田奥陶系碳酸盐岩多期岩溶发育特征及其主控因素,揭示了加里东中期第一幕、第二幕、第三幕和海西早期4个主要岩溶发育阶段,解析了岩溶储层成因演化过程及改造历史,研究认为海西早期及加里东中期第一、第二幕为主要岩溶时期,特别是海西早期最为重要,岩溶发育的主控因素是古构造、岩溶地貌及古水系地质环境。

| Abstract: | The Middle and Lower Ordovician fractured-vuggy reservoirs in the Tahe oilfield experienced multi-stage karstification caused by multi-stage tectonic events from the Middle Caledonian to the Early Hercynian.Based on integration of geological,geophysical and geochemical data,we discuss the development characteristics and main controlling factors of multi-stage karstification of the Ordovician carbonates in the Tahe oilfield.Four main periods of karstification are identified as follows:the 1st Phase,2nd Phase... |
