METHOD OF PURIFICATION OF UNDERGROUND PORTABLE WATER AT CRUDE PRODUCTION

摘要

FIELD: oil-producing industry. ^ SUBSTANCE: the invention presents a method of purification of the underground potable water at a crude production. The method provides for limitation of traffic of pollutions by construction of boreholes and pumping in of solutions of reagents. Along the contour of the site of possible pollution they make a net of boreholes with the a controlled inter-pipe and drill string-borehole annulue space - a compound - boreholes, the distance between which and a number of steps is chosen depending on porosity and permeability of rocks. The steps of the compound-boreholes are placed perpendicularly to the traffic route of the natural stream of the underground potable water, and a pumping in of the solutions of reagents is made through annulue space and inter-pipe space of compounds - holes simultaneously with a crude and a gas production from a pay. The technical result is a reliable provision of purification of underground potable water at simultaneous production of a crude and a gas. ^ EFFECT: the invention ensures a reliable provision of purification of underground potable water at simultaneous production of a crude and a gas. ^ 1 dwg
