Abstract

The invention provides a petroleum logging instrument sensor calibration device including a wood testing room, a sensor, a cold air generation source, and a non-metal pipeline, the wood testing room includes vertically arranged support rods, a bottom layer frame, an intermediate layer frame, and a top layer frame, the bottom layer frame, the intermediate layer frame, and the top layer frame are connected to the support rods through non-metal connecting pieces, a flat board is arranged on the intermediate layer frame and is connected to the intermediate layer frame via non-metal connecting pieces, the top layer framer is provided with a top board, a calibration chamber having an enclosed space is formed between the flat board, the top board, and the support rods, the inner walls of the calibration chamber are provided with insulation layers, the non-metal pipeline is connected with the calibration chamber and the cold air generation source, a fan for conveying cold air is arranged in the non-metal pipeline, and there is no metal within the range of 4m surrounding the wood testing room. The sensor calibration device has no magnetic interference around within the range of 4 meters and is low in cost, and insulation layers which can keep the calibration chamber at 0 DEG C are arranged indoors.

Description

technical field [0001] The invention belongs to the field of petroleum exploration, in particular to a sensor calibration device in a petroleum logging instrument. 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 import...
