煤田测井资料标准化方法研究

摘要

Usually, certain systematic error could be existed in well logging data from different boreholes .To reduce the error, the well logging data normalization plays a significant role on seismic data strata horizon calibration and seismic information interpretation . Through a study area cumulative coal seam sector , whole sandstone sector and low porosity sandstone sector etc .are selected as index beds, using the bipunctate calibrating method carried out logging traces normalization .The index bed eigenvalues contrast analysis have found that taking cumulative coal seam sector and low porosity sandstone sector as index beds to calibrate logging traces has higher ac -curacy and better practical application effect .%不同钻井的测井资料通常会存在一定的系统误差,如何降低误差,进行测井数据的标准化,对地震数据的层位标定以及地震资料的解释起着重要的作用.通过选取某研究区内累积煤层段、整个砂岩段和低孔砂岩段等不同层段作为标准层,采用两点校正法对测井曲线进行标准化.对比分析标准层的特征值后发现,累积煤层段和低孔砂岩段作为标准层对测井曲线的校正精度较高,实际应用效果较好.
