射孔资料自动化处理

射孔校深资料磁定位曲线的接箍深度记号数值一直采用人工方式用尺子丈量，放磁自然伽马曲线与裸眼井的自然伽马曲线以人工方式每25m进行1个井段校深。从相关对比原理和磁定位原理出发，研制了计算机自动校深、自动识别接箍的方法，编制了相应软件，使射孔校深的质量和时效发生了质的飞跃。对套管井的自然伽马曲线和裸眼井的自然伽马曲线进行的井段校深对比长度可以任意选择，使2曲线最大程度也校深在同一浓度上，其一致性的提高大大减少了人为误差；计算机处理校深结果只须3min就可完成，实效性明显提高。

Auto Processing of Perforating Data

Since Jiangsu Oilfield was founded, the numerical values of collar depth marks of the magnetic orientation curves have always been measured through man-made ruler by hand. Natural gamma curves of magnet-releasing and the open hole have been proofread every 25 meters by man. This article begins with the principle of relative contrast and magnetic orientation logging, develops the methods and software of computer auto depth-proofread and auto collar distinguishing, thereby, obtaining higher quality and better result in perforation depth correction. We may correct natural gamma curves from both casedhole and openhole for interval depths. The contrast length of the interval depths may be selected arbitrarily so that depth-corrected intervals of the above two curves will be at the same depth. Therefore, its consistency is improved and artificial errors are reduced. Computer auto depth proofread needs only three minutes, effect of which is obviously higher.
