摘要
测井资料标准化是多井处理、油藏描述、储层评价中不可缺少的必要性基础,从地质学的角度讲,其作用是使研究区各单井具有统一的刻度和度量标准。本文根据本研究区研究范围小、沉积相单一、标准层明显等特征,在本次测井数据的标准化研究确定了使用直方图法对研究区井位有代表性的AC、GR、ILD三条曲线进行标准化。结果表明,对研究区井位AC、GR、ILD标准化后,效果较理想,符合实际地质特征,为后续评价工作做好了充分准备。
Logging data normalization is necessary for multi-well processing,reservoir description and reservoir evaluation.From geological angle,its role is to make every single well in the study area having a uniform measurement standard.Based on the analysis of qualitative and quantitative method of different kinds of logging data normalization,trend surface is used in more than 80 wells to analyse three kinds of curves which is typical AC,GR and ILD logs in the area to establish the trend equation.After determining characteristic value of logs,the normalization equation is used to process every single well to complete the normalization work.The innovated combination of trend surface analysis and normalization equations is used in the study area,and computer programming makes normalization effect more visualized.The results show that normalization of AC,GR,ILD logs of 80 wells has got satisfied effect.It corresponds with the actual geological characteristics and makes full preparation for subsequent evaluation.
