is design for cement bond logging and investigation of open-hole sections by kinematic and dynamic parameters of elastic waves.
Problems to be solved
• identification of low-strength cement intervals, detection of volume-contact defects of cement bond;
• lithologic segregation of a section, identification of reservoirs and evaluation of reservoir porosity.
Features and Advantages
• ZAS-03 tool with a three-element probe construction and an electronic circuit is fully compatible with the equipment – UZBA-21 and UZBA-21, widely used in Russia;
• replacement of the out of date downhole tools in UZBA-21 and UZBA-21A equipment by ZAS-03 tool keeps up using of the running investigation methods, the respective techniques as well as the interpretation software;
• tool conveyance to the investigation interval through the drill pipe with inner diameter 90 mm.
Delivery set: downhole tool, spare parts kit, control unit.
