摘　　要：电成像测井资料是分析沉积环境和沉积相的重要手段,通过提取地层产状,以此研究岩层的层理构造,分析古沉积环境,寻找有利的勘探方向。若测量井是斜井,要对所得产状做井斜校正。井斜角及井斜方位角(测斜方位资料)是井斜校正中的重要校正参数。为了得到准确的解释结论,需要对实测测斜方位资料的准确性进行判断。提出了一种对实测资料进行质量评价的方法及相应的校正方法,实际处理结果表明,所提方法可行,其校正效果与斯伦贝谢校正结果一致。Electrical imaging logging data were an important method to analyze the sedimentary environment and sedimentary facies to study the rock bedding structure,analyze the ancient sedimentary environment and look for favorable exploration direction by extracting the attitude of stratum.If the measured well was inclined,it was needed for deviation correction,in which the well inclination and azimuth were the crucial correction parameters.To get the accurate interpretation result,it was necessary to judge the accuracy of the measured data.In this paper,a method for evaluating the quality of the measured data and the corresponding correction algorithm are presented,after processing the measured data,the result show that the quality evaluation method is feasible,and the correction effect is consistent with the result of Schlumberger.
