【摘要】 根据岩心描述、薄片观察、X CT扫描以及钻井、测井等资料 ,研究了酒西盆地青西坳陷柳沟庄—窟窿山油藏裂缝性储集层的类型及特征 ,分析了控制裂缝发育的地质因素及裂缝对油气的控制作用 ,认为储集层裂缝有 3种基本类型 ,即构造裂缝、构造溶蚀缝和饼状破裂 ,主要受构造应力场及构造位置等因素的控制。根据裂缝形态、充填特征及其相互关系 ,裂缝的形成主要有 3个期次 ,其中喜马拉雅运动晚期形成的第三期裂缝对油气运移和聚集最有效。研究结果表明 ,裂缝是柳沟庄—窟窿山油藏主要的储集空间和控制油气富集的因素。图 6表 2参 6更多还原

【Abstract】 According to the data of core description, thin section observation, X CT scanning and analysis of drilling and logging data, the authors of this article studied the fissure type and character of Liugouzhuang Kulongshan reservoir, and analyzed the geological factors controlling the development of fissures and the controlling effect of fissures on gas and oil. The authors hold that the fissures are divided into three basic types-structural fissure, structural solution fissure and pie shaped fissure. They are mainly controlled by factors such as tectonic stress field and tectonic position. According to the shape and filling character of fissures and the relationship of the two factors, the formation of fissures can be divided into three stages. The fissures formed in the third stage during the late Himalayan movement are the most effective fissure for petroleum migration and accumulation. It is concluded that fissure is the main controlling factor of reservoir space and petroleum accumulation of Liugouzhuang Kulongshan reservoir.更多还原
