is designed for vibrational impacting on bore-hole annulus during oil-and-gas cased wells cementing.
Features and Advantages
• refinement of formation isolation by optimized plug-back in zones of shale breaks, caverns and eccentric casing pipes;
• impacting on bottom-hole area of pay formation for enhanced oil recovery in producing well;
• impacting on bottom-hole area of pay formation for enhanced well injectivity;
• reconditioning of clay/polymeric-clay mud geological properties and reducing cake thickness in open hole during prospecting by means of wireline core sampler and hydrodynamic logging tools.
The set consists of a downhole tool, control console, transformer, communication cable, spare parts, tools and accessories.
VEMS-D electromechanical vibrator is to be used in boreholes of 190-300 mm diameter, with casing of 140-245 mm diameter. It is to be run with a triple-core or seven-core armored logging cable 4200 m or 5600 m long, respectively.
