简述了传统感应测井仪在数据处理上的局限性,提出了存储式阵列感应测井仪数据处理方法,并简单介绍了存储式阵列感应测井仪工作原理和响应特性。数据处理是存储式阵列感应测井仪的核心之一,该仪器利用多个不同间距的子阵列和多个工作频率采集井下丰富的地层信息,送入地面系统进行数据处理,可聚焦出不同分辨率和不同探测深度的测井曲线。数据存储和坏区管理是该仪器另一核心技术,用于对测井原始数据的管理。实际应用表明,该仪器能准确地测量地层电阻率,真实反应地质构造,数据处理方法先进。

The limitation of the traditional induction logging tool in data processing is introduced,and new demand for data processing for the memorized array induction logging tool is presented,and the tool＇ s working principle and response characteristics are also simply introduced. Data processing is one of the core technolog of the memorized array induction logging tool. Several sub arrays with different spacing and several different working frequency are utilized to collect underground formation information,which is sent to the ground system for data processing and is focused into logging curves of different resolution and different detection depth. Data storage and bad area management is another key technology of the tool,which is used to manage the original data of well logging. The practical application shows that the tool can measure the formation resistivity accurately and reflect the geological structure correctly. The data processing method is advanced.
