| titleOfInvention | Calibration checking installation for acoustical logging equipment |
| abstract | The invention relates to a measurement technique and is intended for the calibration and control of acoustic logging equipment when measuring interval time and attenuation coefficient. The aim of the invention is to improve measurement accuracy and reproducibility of measurement results. The goal is achieved by the fact that in a calibration installation for acoustic logging equipment the coordinate device is made in the form of horizontal and vertical carriages. Carriages are equipped with prisms with clamps. The horizontal carriage is mounted on guide rods, provided with a movement lock and a bracket for securing a vertical guide. A vertical carriage with an electro-acoustic transducer is installed on the vertical guide. One of the guide rods of the horizontal carriage has risks in the form of grooves at fixed distances. When moving the coordinate device along the axis of the bath and the sound guide of the prism of the horizontal plate, contact is maintained with the cylindrical. the top of the bar with the risks of two generators, and with the other bar - one. Under the action of the mass of the coordinate device and the force developed by the clamps, this contact is not broken and the backlash-free movement of the coordinate device along the rods is realized. When the coordinate device moves along the bath axis, the vertical carriage moves on the one hand under the action of its mass and spring, and on the other under the action of the reaction force on the stop roller, copying the sound guide profile. When the coordinate device moves along the bath axis, the distance between the receiver and the sound guide remains constant. As a result, only the path of the passage of the elastic wave through the conduit is changed, and the path of the fluid remains constant. 4 il. ยง W N9 EO h | ate |
