| Abstract: | Inclinometer for artesian well regarding fluxgate technology and gravity acceleration as operation principle is introduced,and operation principle of two kinds of sensors and the structure design of inclinometer are expatiated on.It deduces mathematical formula of computing well oblique angle,azimuth angle and tool angle.The inclinometer measures signal using amplitude value phase method and 2 times harmonic method,and processes the data using internal single chip processor.It eliminates the influence of various error by the method of revising gathered data,so that measuring accuracy of the inclinometer gets marked exaltation. |
