【摘要】 阵列感应测井仪是近几年推出的一种新型感应测井仪器，阵列感应测井具有测井信息多，资料处理复杂等特点。为了更好地利用这类测井资料，本文综合利用测井新技术及面向对象的软件工程学方法，结合油田测井解释实际，开发了《阵列感应测井二维反演软件》。为测井解释工程师提供了一个对阵列感应测井资料的精细、直观、方便的软件工具。 在总结分析了前人大量研究工作的基础上，应用测井解释理论结合计算机技术，研制了实用的阵列感应测井二维反演软件：根据阵列感应测井原理、仪器性能和几何因子理论，研究阵列感应测井响应与井眼周围径向电阻率之间的关系；建立了阵列感应测井二维反演迭代算法；在开发过程中，采用内存映射文件、内存DC绘图、局部重绘等技术实现了大数据量巨幅测井图形的快速度、高质量绘制以及图形的连续滚动显示，提高了绘图效率。 本软件用户界面友好，并应用到了实际测井解释工作中，对准确评价地层参数起到了重要作用。更多还原

【Abstract】 The Array induction logs device was launched in recent years a new type of induction logging equipment, it has the features of more information and data processing complex. To make better use of such logging information, it is necessary to extracting information processing and analysis. With new Well Log techniques and Object-Oriented software methods, Compounded with the practices in oil field, we’ve developed a software system named Array Induction Logs Two-dimensional inverse interpretation software, which provide a logging engineer explained information of array induction logs, Refined, visual, convenient software tool.At the conclusion of an analysis of the predecessors on the basis of extensive research, the application of computer technology in conjunction with logging interpretation theory, developed for the two-dimensional array induction inverse logging software: According to array induction logging principles, equipment performance and geometric factor theory, researched the relationship between array induction response and radial resistivity of the borehole; created two-dimensional array induction logging inverse iterative algorithm; In the development process, using existing shine upon documents, within DC. Mapping, local technical achieved great getting a huge volume of data logging devices for the rapid and high-quality maps and graphics of a rolling show that increased efficiency mapping;The software has a friendly user interface, and applied to the work of interpreting the actual logging, stratum parameters for the accurate evaluation has played an important role.更多还原
