Innovative Approaches to the Formation of Environmental Safety at the Objects of Oil and Gas Production

Abstract

In order to solve the problem of environmental safety improvement and the effectiveness of flushing out of well that are being drilled a modernized scheme of drilling rig pumping-circulatory system has been designed. System approach of modernizing separate elements of pumping-circulatory system has been used. The maximum air-tight pumping-circulatory drilling rig system has been designed. While doing this the transportability, ease of assembly, ease of operation of the system had been taken into account. The most of attention was paid to designing the tanks for mud and chemical reagents storage. The offered pumping-circulatory system effectively prevents and reduces the evaporation of the mud containing hazardous substances at different sections of pumping-circulatory system while conducting different technological operations during the process of drilling and also increases the level of radiation safety. There are separate sections that do not include the advanced pump-circulation system of the drilling rig. These include: the surface of drill pipes raised from the well, moistened with drilling mud and equipment for cleaning the solution from the harvested rock. Using a device of a new design for cleaning the surface of drill pipes from the drilling mud and partially sealed devices for cleaning the drilling mud from the harvested rock have been proposed. Such an approach will avoid the entry harmful substances into the environment and prevent harmful effects of aggressive substances on health personnel of drilling rig.
