陀螺测斜仪
GDL-50D 陀螺测斜仪采用三自由度框架陀螺结构配合全新设计的数字电路,测量精度和可靠性都得到了极大的提升。适用于强磁异常矿区和已经下了套管的孔径不小于56 毫米的钻孔内,进行顶角和方位角的多点测量,用以确定钻孔的三维位置。
一、主要技术特点
1、采用高速旋转的三自由度框架式陀螺作为方位角定向和测量元件,零点漂移小,是磁性矿地区和铁套管的钻孔中测量方位角最理想的定向器件。
2、采用高精度的双轴倾角传感器作为顶角的测量器件,经24位AD采样、数据处理后得到顶角数据。
3、由地面控制箱将方位、深度信号混合后传至计算机,计算机进行数据处理、保存、并画出三维轨迹图。
二、主要技术指标和参数
1、测量范围: 顶角 0~50°;方位 0°~360°;
2、测量精度: 顶角测量误差: ±0.2°;
方位测量误差: ±5°(顶角≥1.5°);
方位漂移: 每小时不大于12°;
3、测量深度: 1200m;
4、工作电源: AC220V±10%/50Hz;
5、整机功耗: 约75W;
6、环境温度: -10~55℃;
7、井下电缆: 仪器使用四芯电缆(电缆内阻 < 85Ω/100m);
8、外形尺寸: 井下测量探管:Φ50㎜×1880mm;
地面控制箱: 370㎜×290㎜×200mm;
三脚架: 950㎜×80mm。
注:笔记本电脑、绞车、线缆另配。
