测井曲线深度一致性检验与校正——以准噶尔盆地乌伦古凹陷石炭系地层测井曲线为例

Depth Consistency Check and Correction of the Logging Curves——Taking the Carboniferous Formation Logging Curves in Wulungu Depression,Junggar basin as an Example

测井是获取地层信息的重要手段,测井曲线的一致性校正是正确提取测井信息的重要前提。在测井资料解释与运用过程中,人们往往重视环境校正而忽视了深度一致性检验与校正。通过对准噶尔盆地乌伦古凹陷石炭系地层测井曲线隔步长相关系数的研究,认为测井曲线间隔步长相关系数可作为深度一致性检验的重要指标。

Well logging is an important method to obtain formation information. Consistency correction of the logging curves is an important prerequisite to correctly extract the information. In logging interpretation and application, people pay more attention to the environmental correction and neglect the depth consistency check and correction. It is thought that the logging interval step correlation coefficient can be taken as an important indicator of the depth consistency check and correction through research of the correlation coefficient of Carboniferous strata logging curves in Wulungu ancient depression in Junggar basin.
