岩性元素扫描测井在准确识别岩性中应用

Application of Litho Scanner Logging in Accurately Identifying Lithology

对于非常规储层和复杂岩性储层,利用常规测井曲线准确识别岩性、求取地层参数比较困难,元素扫描(Litho Scanner)测井通过对地层中元素的直接测量,能够提供地层中元素含量,对于特定的岩石(碎屑岩、碳酸盐等),可以通过元素含量计算地层中不同矿物组分的含量,进而进行对岩性的准确识别,识别出地层中绿泥石、蒙脫石、伊利石、钠长石、石英、方解石、白云石和黄铁矿等地层矿物及其含量,完成地层岩石矿物的评价。

For unconventional reservoirs and complex lithologic reservoirs,it is difficult to accurately identify lithology and obtain formation parameters using conventional logging curves.Litho Scanner logging can provide element content in the formation through direct measurement of elements in the formation.For specific rocks(Clastic rock,carbonate,etc.),the content of different mineral components in the formation can be calculated through element content to accurately identify lithology,Identify Chlorite group,montmorillonite,Illite,Albite,quartz,Calcite,dolomite,Pyrite and other formation minerals and their contents in the formation,and complete the evaluation of formation rock minerals.
