Segmented Bond Tool And Application

Segmented Bond Tool (SBT) is an excellent technology applied to Primary Cement Evaluation, and it has recently been servicing in Field Producing and obtaining satisfying applicability effect.Researches of profile and geometry of piezoid, constructer and dynamic characteristics of transducers, electrical behavior and match of piezoid accompanied by massive indoor and on-site experiments and numerical models indicate that one of the most important units are transducers whose properties ( frequency characteristic, insulating property, working life ) are mainly affected by the choice of piezoid bonding material and manufacturing process. The properties of SBT transducers include frequency characteristic, acoustic directional characteristic, and dynamic characteristic and electrical behavior and so on; however, they are determined by the material, match, and geometry bonding process of piezoid.To select transducers in accordance with their uniformity, so the SBT manufactured are steady and reliable, and the main technical descriptions of these tools fulfill expected requirements well. It is believed that SBT has obtained the advanced level of the same kind of logging tools in the whole world, and it will play an important role in the development of oil field because of its popularization and application.
