六臂地层倾角测井仪功能电路及液压测试器实现

Design of the logging function circuits and hydraulic test device of six arm dipmeter

六臂地层倾角测井仪主要测量6条微电阻率和6条井径曲线以及利用磁力计与重力加速度计计算得到的井斜方位角和井斜角。而对6条微电阻率曲线经过相关对比,可确定地层倾角和方位的判断,进而识别地层的沉积环境。文章分析了六臂地层倾角测井仪的信号采集、信号编排和信号传输电路设计,同时根据液压装置的工作原理,设计了一种液压测试装置,用来判断六臂地层倾角测井仪液压装置的可靠性。

Six arm dipmeter can measure six micro resistivity and six caliper curves, and as well as the gravity accelerometer and magnetometer parameters which was used to get its well deviation and azimuth angles. With the relation and comparison methods for six resistivity curves, stratigraphic dip and azimuth were determined, and then the strata sedimentary environments were identified. The design methods for the circuits of signal acquisition, signal array and signal transmission of six arm dipmeter was discussed in this paper. And according to six arm dipmeter hydraulic propeller principle, a test device had been designed for the judgment of the reliability of the six arm dipmeter hydraulic equipment.
