Orientation survey pipe nipple is in-built is equipped with three mutually orthogonal acceleration transducers (A1, A2, A3) and three fluxgate sensors (M1, M2, M3).Wherein, A1, A2, A3 are for measuring the gravity acceleration g of the earth; M1, M2, M3 are for measuring the geomagnetic field intensity m of the earth.According to the output valve of these six sensors, calculated by algorithm, the engineering parameters such as required hole angle (T) and azimuth (A) can be obtained.
Drill bit needs to cut hard rock in drilling process, and consequent severe impact shakes the deviation usually causing orientation survey pipe nipple to be measured, and even causes the damage of its built-in acceleration sensor.Because the Sensitive Apparatus of high accuracy acceleration transducer all adopts quartz pendulous reed, and quartz pendulous reed essence crisp fritter is frangible, can permanent damage after being subject to severe impact vibrations.
The built-in acceleration transducer of existing orientation survey pipe nipple adopts flange and the fixing mode of screw, and the frangible quartz pendulous reed damping of crisp fritter places one's entire reliance upon the axial vibration damper and radial shock absorber that orientation survey pipe nipple two ends arrange.The severe impact produced in drilling process shakes the deviation usually causing directed pipe nipple to be measured, and even causes the damage of its built-in acceleration sensor.
