海拉尔盆地苏德尔特古潜山裂缝发育特征

Characteristics of fracture development in Sudeerte buried hill in Hailaer basin

为查明潜山裂缝特征与分布规律,根据海拉尔盆地苏德尔特潜山的岩心观察统计资料,研究了裂缝类型、密度、宽度、充填期次等特征,建立了岩心统计和成像测井解释裂缝线密度的定量关系,对研究区下古生界裂缝发育规律进行了平面预测.结果表明,苏德尔特潜山发育程度有东高西低、南高北低的趋势.

According to the core and imaging log data of Sudeerte buried hill in Hailaer basin,the type,density,width and filling time of fractures are studied.A quantitative relationship between the fracture density derived from core statistic data and imaging log data is established and planar distribution of fracture in the target area is forecast.The results show that the fractures in the eastern part of the target area are better developed than that in the west,and the fractures in the south part of study area are better developed than that in the north.
