塔河油田碳酸盐岩油藏致密段划分及意义
|
摘要
针对塔河油田奥陶系碳酸盐岩缝洞型油藏目前储量动用程度低、开发效果变差的特点,以纵向岩溶分带、油井分段开采特征为基础,首次提出缝洞型油藏致密段定义,利用岩心、测井、单井纵向岩溶带分布特征和开发动态特征及地震波阻抗反演等,建立缝洞型油藏高阻致密段划分标准。采用点、线、面相结合技术流程,研究塔河油田6、7区不同致密段分布。该方法已应用到塔河油田开发中,效果较好,成为"十二五"缝洞型油藏精细描述和提高储量动用主要方法之一。
For the characteristics that the reserves produced degree and development effect of Ordovician fractured-cavity carbonate rock reservoirs in Tahe oilfield decrease gradually,we use vertical of Karstification and the sublevel development of Well,first proposed definition of dense layer in fractured-cavity reservoir.And using drilling core,well logging,vertical of Karstification development behavioral characteristics and seismic wave impedance inversion method,established the distinction criterion of resistive dense layer,studied the distribution of different dense layer in Tahe six & seven district.This technique has been applied to the Tahe Oilfield Development,and it has become one of the most useful methods of fine reservoir description and producing degree of reserves during the current 12th Five-Year Plan.
