Abstract

The invention provides a sensor calibration device which comprises a wood testing house, a sensor, a cold air generating source and a non-metallic pipe. The wood testing house comprises a vertically arranged support rod, a bottom frame, an intermediate frame and a top frame. The bottom frame, the intermediate frame and the top frame are respectively embedded on the support rod. The intermediate frame is provided with a flat plate which is embedded in the intermediate frame. The top frame is provided with a top plate. A calibration room with a closed space is formed among the flat plate, the top plate and the support rod. An insulation layer is arranged on the inner wall of the calibration room. The sensor is located in the calibration room. The calibration room and the cold air generation source are connected through the non-metallic pipe. No metal exists within 4m around the wooden testing house. The length, the width and the height of the calibration room are respectively 2m, 2m and 2.5m. The calibration room is 2m from the indoor ground. The sensor calibration device provided by the invention has low cost which is about 8,000 yuan. The thick insulation layer is arranged indoors, so that the calibration room can be kept at zero degree.

Description

technical field [0001] The invention belongs to the field of petroleum exploration, in particular to a sensor calibration device. Background technique [0002] MWD (The Measurement While Drilling) is a wireless measurement while drilling system powered by a downhole turbine generator. MWD collects data from sensors installed on the drill bit and transmits the data to the surface with the help of pressure pulses from the mud circulation system. The practical application of MWD has brought a new leap to directional drilling technology. It is a real-time monitoring system for downhole drilling tools, which can provide directional drilling workers with parameters such as well deviation, azimuth, tool face direction and bottom hole temperature at any time, so that Workers can know the whereabouts and working status of downhole drilling tools at any time, which is convenient for controlling the well trajectory. Since the MWD sensor is very important for monitoring the downhole dr...
