Lyakh M. M. Experimental and industrial research on foamgenerating devices [Електронний ресурс] / M. M. Lyakh, V. М. Savyk, P. О. Molchanov // Науковий вісник Національного гірничого університету. - 2017. - № 5. - С. 17-23. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2017_5_5 Purpose. Finding out and researching rational constructive parameters of foamgenerating devices. The purpose is achieved through implementation of the following tasks: carrying out computer research on multi-nozzle foamgenerating devices and choosing rational geometric parameters and modes of their work that would provide high efficiency of washing wells with foam; finding out relation between geometrical shapes, parameters, work modes of foamgenerating devices and the efficiency of foam creation while performing experimental and industrial research; developing and explaining the rational scheme of strap in equipment and devices for washing oil and gas wells with foam in the process of industrial studies. Methodology. It includes: experimental definition of the main parameters and work modes, considering the construction change of foamgenerating device; computer modelling of foam generating was performed with the purpose of optimizing its internal constructive elements. Findings. Relations between geometrical shapes, parameters, work modes of foamgenerating devices and the efficiency of foam generating have been established. Originality. Experimental studies on streaming of liquid, air and foam and their mixture through constructive elements of the equipment allow establishing regularities of the relation of the efficiency of foam generating with parameters and work modes of foamgenerating devices. In addition to the above: relation between quality of foam generating and constructive peculiarities of single elements in the foamgenerating device has been defined; analytic dependences of movement of streaming of liquid, air and foam and the efficiency of foamgenerating device work from their constructive peculiarities have been experimentally explained; a method for choosing optimal constructive shapes of elements of foamgenerating devices that influence the formation of streams of liquid, air and foam have been scientifically explained. Practical value. Rational geometrical shapes and parameters have been defined, optimal work modes of foamgenerating devices have been set, which are the basis for creating new high efficient devices. We have suggested a row of methods and instrumentalities of constructive and technological character for booming the efficiency of well cleaning with foam solution. The results have been used during the development of pump-circulating system for well cleaning with foam solution. | ||
