Функціонально-вартісний аналіз магнітних ловильних пристроїв
Accidents happening during the construction of oil and gas wells cause remaining metal objects on the bottom holes. It is known that magnetic fishing tools are the most effective for retrieving ferromagnetic debris from wells. In order to research the technical and economic efficiency of existing tools, a value analysis was carried out. For this purpose, data on the cost of serial models of fishing tools based on permanent magnet has been collected. By method of regression analysis, it was researched the functional dependence of specific prices on the main parameter of fishing magnets, namely lifting force. As a result, a mathematical model of the average price level for the studied magnetic devices is obtained. The obtained results allow to assess competitiveness on the world market of the magnetic fishing tool model.
