中文摘要：

地震储层预测时需要高精度的测井数据,对测井曲线不仅在储层处要进行环境校正,而且在非储层处也要做环境校正。为了消除井眼扩径和其他影响因素对测井曲线的影响,针对声波和密度等孔隙度测井提出了一套校正办法。首先要找出测井曲线的失真,然后针对引起失真的原因,分别针对声波测井和密度测井提出具体校正办法,主要包括基于阵列声波测井的声波时差重新提取和其他资料的重构-编辑法。上述方法在川东北碳酸盐岩区块进行了实验,经分析与对比,证明该方法是有效的,思路和方法对其他区块也有借鉴意义。

英文摘要：

Seismic reservoir prediction requires high-precision logging data, namely Environment correction of logging data is necessary in reservoirs as well as non-reservoirs. To Eliminate the impacts of borehole collapse and other factors on logs, put forward the first to find out the abnormal of log curve, according to the abnormal, a set of correction methods for the sonic logging data and density logging data are proposed of respectively, such as reprocessing of array acoustic logging data and reconstruct-editing method. These methods were be used in carbonate rocks in the northeastern of Sichuan province. The results prove show these methods effective and correct. The ideas and methods are promising for other formations and areas.
