摘要
海拉尔盆地储层分为砂岩、砂砾岩、变质岩风化壳(以裂缝型为主)等类型储层。海拉尔盆地裂缝储层压力恢复曲线特征,油藏的储渗条件决定了试井曲线类型,试井曲线类型是油藏储渗情况的动态再现。经对海拉尔盆地裂缝储层试井曲线特征分析,将压力恢复试井曲线分为:视均质、双重介质、裂缝三种基本类型。通过分析可以认识海拉尔裂缝储层的渗流介质类型和储层发育特征,进而精细评价油藏。
Reservoirs in Hailaer basin are divided into sandstone,glutenite reservoir and metamorphic rock weathering crust( give priority to with fracture). Its pressure buildup curve characteristics,reservoir's permeability conditions determine the type of well test curve,which is dynamic reappearance of reservoir permeability. Through analysis of well test curve characteristics to fracture reservoir in Hailaer basin,pressure restore well test curve can be divided into three basic types of homogeneous,dual medium and crack. Through analysis,percolation medium types and reservoir development characteristics of Hailar fracture reservoir can be known,and the fine evaluation of reservoir can be done.
