Product Information

1. Product usage: sector acoustic logging instrument (SBT) is used to test the cementing quality within 360-degree range of the well through the transducers on 6 polar plates, and each of which contains 2 transmitting transducers and 1 receiving transducer. Each group of transducers is tested in a mutually supplementary manner so as to achieve a better measurement. This instrument is of sidewall contact structure, which is unaffected by the well liquid and high in measuring sensitivity. 2. Product superiorities: measurement of the first interface first-wave amplitude; analysis of the first interface quality; and VDL wave collection.
