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; 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; Delivery set: downhole tool, spare parts kit, control unit. Acoustic sonde formula: ZAS-03 I20.5I11.5P Max. operating temperature, oC 120 Max. hydrostatic pressure, MPa 80 Borehole diameter, mm 100-250 Downhole tool dimensions, mm diameter (without centralizers) length 73 up to 3500 Used cables core number, pcs 3 Weight, kg 45
• lithologic segregation of a section, identification of reservoirs and evaluation of reservoir porosity.
• replacement of the out of date downhole tools in UZBA-21 and UZBA-21A equipment by ZAS-03 tool keeps up using of the running investigation methods, the respective techniques as well as the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.
