摘要
为了研究塔河油田奥陶系断裂对油气运聚的影响,采用分形研究方法对塔里木盆地塔河油田中下奥陶统顶面(T74界面)断裂体系的分布特征进行研究。研究结果表明:断裂体系的分维值与其空间分布的复杂程度密切相关,若断裂体系分维值越高,则断裂体系空间分布越复杂,深源油、气向上运移的通道条件越好;若断裂体系分维值越低,则越不利于油气运移的发生;分形研究方法在塔河油田得到应用,不仅有助于该区油气富集规律的研究,而且有助于断裂系统的研究。
In order to study how the fracture affects the hydrocarbon migration and accumulation in Tahe Oil Field, fractal method was employed to study the fractal features of fracture system on the top surface of middle-lower Ordovician succession in Tahe Oil Field. The results show that the value of fractal dimension can be used to some degree quantitatively to describe the hydrocarbon accumulation abundance, that is, the higher the fractal dimension, the more complex the distribution of the fracture. The successful application of the fractal methods to Tahe Oilfield has significance not only in predicting the hydrocarbon accumulation in practice, but also in discovering new methods to describe fracture system in theory.
