摘要
测井资料质量控制为储层预测提供保障。龙凤山营城组声波和密度曲线失真较为严重,为提高测井曲线质量,以LB1井为主要研究对象,首先利用井径曲线结合密度和声波的交会图版判断出井曲线的失真段,然后依次利用经验公式、岩石物理建模及多元拟合方法对声波和密度曲线进行重构,并对三种预测方法的适用性及结果进行了对比分析,最后通过质量控制和效果评价认为,多元拟合方法重构曲线相对有效可行,重构后井—震相关性得到较大改善。
The quality control of logging data provides the guarantee for reservoir prediction. Due to serious distortion of acoustic and density logging curves of Yingcheng formation in Longfengshan area, the quality of logging curves should be improved. Take well LB 1 as main research object, firstly, cross plot of caliper curve combined with acoustic and density was used to distinguish dis- tortion section, secondly, empirical formula, rock physics modeling and multivariate fitting method were used to reconstruct acous- tic and density curves, thirdly, the comparison analysis of adaptability and results of three prediction methods were conducted, fi- nally, through quality control and effect evaluation, it concluded that multivariate fitting method was effective and feasible to recon- struct curves, and after the curve reconstruction, well and seismic correlation was greatly improved.
