摘　　要：提出了基于压电陀螺的矿井测斜系统，以解决磁强计或传统测斜惯性仪表在小井径或套管井测量领域的受限性。介绍了陀螺测斜仪的系统集成方案，并采用TMS320F281XDSP实现了数据采集、数字滤波和实时解算。所设计的试验样机倾斜方向角测量范围0°～360°，误差在±0．2°以内，倾斜角测量范围0°～15°，误差在±0．04°以内，达到探矿用井的测量要求，并具有体积小，成本低，性能稳定的特点，具有完全实用的工程应用价值。A new well measuring inclination system based on Piezoelectric Gyro was presented to eliminate the limit of magnetometer or conventional measuring inclination inertial instruments applied in slim hole and cased hole in well logging. The system integration scheme of Gyro-inclinometer was introduced and data acquisition, digital filter and real-time solution were realized by using TMS320F281X DSP. The azimuth angle measurement range of designed test prototype was 0°-360°, error ≤ ±0.2°. The measuring range of the tilt angle was 0°-15°, error ±0.04°, which could meet the qualification of the prospecting. The test prototype also had the advantage of small volume, low cost, stable performance and with whole complete engineering value for application.
