摘要
ＤＥＶ４３ＸＡ井斜测井仪是一种数字化的高精度连续测 斜系统。它使用磁力计和加速度计作为敏感测量元件，由单片机采集传感器测出的姿态量， 在井下仪器中计算出方位角和倾斜角，数据按标准ＰＣＭ格式传送至地面。再由地面仪器对ＰＣＭ 信号进行解码，得到所需的测井数据。
DEV43XA continuous deviation tool is a kind of high precision continuous deviation survey system. It adopts magnetometer and accelerometer as its sensitive components. Deviation and azimuth angles are calculated in the down- hole tool by the singlechip computer according to the data massured by the transducer. Data axe sent to the surface system in the standard PCM format. The surface system decodes PCM signals and gets logging data.
