| An accelerometer having a plurality of proof masses adapted to move relative to a casing in response to accelerations of the casing. The proof masses differ with respect to mass or size so that they respond differently to forces thereon as a result of the acceleration. An output signal is generated in response to a predetermined movement of each of the proof masses.

| 140 | GRAVITY ACCELERATION MEASUREMENT APPARATUS AND EXTRACTION METHOD IN A ROTATING STATE | US15553558 | 2016-11-12 | US20180223646A1 | 2018-08-09 | Wenxiu ZHANG; Wenxuan CHEN; Qingyun DI; Jianguang LIU; Yuntao SUN; Yongyou YANG; Jian ZHENG |
| An apparatus for measuring gravity acceleration of a drilling tool comprises sensors and a measurement circuit. The sensor comprises a three-axis gravity accelerometer, a reference measurement sensor and a temperature sensor. The three-axis gravity accelerometer measures acceleration component signals in three mutually orthogonal directions, and the reference measurement sensor generates a signal that varies with rotation and is not affected by vibration or shock to serve as a reference signal. The temperature sensor measures the temperature in the apparatus to compensate the temperature effect of the gravity accelerometers. The measurement circuit acquires output signals of the sensors and performs cross-correlation processing on the accelerometer components using the reference signal to extract gravity acceleration signals so as to eliminate centrifugal acceleration, vibration, shock and other interferences generated by rotation. The non-interference gravity acceleration signals is used for calculating an inclination angle and a toolface angle of a drilling tool in the rotating state. | ||||||
