Kuksanov V.F., Koveshnikov E.A. IMPROVEMENT OF TECHNOLOGY FOR UTILIZATION OF OIL WELLS DEVELOPMENT WASTEModern technologies of wells development after overhaul are aimed at resuming the inflow of reservoir fluid, restoration of throughput and stability of the normal operating mode of the well. Activities are carried out after completion of drilling, or during secondary opening and repair, when the well is filled with a muffling liquid and other liquids, and materials used during drilling and repair that imped the movement of formation fluid into the well. Closed technologies are very rare for the Russian oil and gas industry, and existing methods are not always efficient, so the question of finding rational ways of recycling wastes is still acute. The purpose of this study is to consider the possibility of introducing changes into the process of waste utilization generated during the overhaul of gas wells located on the territory of the Orenburg gas condensate field. The authors proposed two variants for upgrading the scheme for liquid waste pumping. In the first variant, pump exhausts, instead of direct discharge into the air, are sent to the degassing line of the separating unit, thus creating a closed scheme for pumping the material to be utilized. In the second case, a separate degassing line is mounted, which is directed to the horizontal flare unit straightly from the tanker. The improvement proposed by the authors makes it possible to reduce the level of air pollution with hydrogen sulphide on the territory of the working area of the repaired wells to the norms not exceeding MPC. Key words: waste utilization, gas well repair, reservoir fluid, wells development, stationary plants, vacuum pump, air pollution, system modernization.
