岩芯钻探过程中，钻孔延伸的顶角、方位角和孔底的泥浆压力是井眼的重要参数，而现有的测斜仪无论是在使用环境或使用精度方面均达不到深孔取芯钻探的使用要求。基于此，本文设计了一种基于光纤陀螺和加速度计的测斜仪，仪器应用于绳索取芯钻进，在仪器加工完成后进行了大量的室内及现场试验，试验结果表明仪器满足实际深孔取芯钻探工程的使用要求。

Apex Angle,azimuth angle,and the mud pressure in bottom are critical parameters while drilling.But the current gradiograph can not meet the operating requirements of deep hole drilling not only in operating environment but also in precision.So,a gradiograph was designed which based on fiber optic gyroscope and accelerometer,the gradiograph is used in rope core drilling.When completed,a numbers of tests were operated,and the experimental result proved that the instrument satisfy the demands of practical engineering.
