摘要
Abstract
Karstic fractured-vuggy carbonate reservoir is the most important type of Ordovician reservoirs in Tahe Oilfield. While the types, stages and models of paleokarst are important in the study of the laws of reservoir development. According to its features , the karst water is divided into two types, atmospheric water and non-atmospheric water. Usually, the former occurs in hypergenesis condition. Based on the geo-logic characteristics of Ordovician paleokarst in Tahe Oilfield, hypergenesis can be divided into Episode I , Episode Ⅱ, Episode Ⅲ in mid-Caledonian, early-Hercynian, later-Hercynian. Furthermore, in view of karstic characteristics in every stage, relevant karstic models have been set up. They will play a significant role in revealing the development laws of Ordovician reservoir in Tahe Oilfield, and forecasting beneficial reservoir lines.关键词
