| 摘 要： | 古岩溶作用形成的溶洞、溶孔、裂缝构成了塔河油田奥陶系缝洞型油藏的重要储集体,控制油气分布。塔河油田奥陶系古岩溶发育主要经历了加里东期和海西早期岩溶作用的改造,通过对塔河油田岩溶作用演化及发育期次的研究,认为O3s尖灭线以北为海西早期岩溶及加里东期岩溶共同作用的结果,以南区域主要为加里东期岩溶发育区。利用岩心、钻井、录井、测井、地震等资料相结合的方法,将塔河油田溶洞储集体从成因上划分为侵蚀型溶洞、异地沉积物充填型、原地沉积物充填型、塌陷型溶洞4种类型。结合塔河油田岩溶储层发育特征,建立了塔河油田奥陶系岩溶洞穴型储层的纵向分布模式和平面分布模式。

| Abstract: | Karst caves,holes and cracks are important oil conductivity to Ordovician fractured reservoir and control the distribution of oil and gas in Tahe oilfield.Karst system of Ordovician reservoir in Tahe oilfield developed from Caledonian to Early Hercynian.Based on the karst origin,evolution and growth mechanism of Tahe oilfield,it is considered that the north area of pinch O3s is the result of karst in Caledonian and Early Hercynian,and the south area of pinch O3s is the result of karst in Caledonian.Utilizat... |
