Abstract

Способ повышения добычи метана из подземного углеродистого отложения посредством химического стимулирования образования дополнительной свободной площади поверхности либо трещин в органических составляющих упомянутого отложения и обеспечения выделения метана, адсорбированного неорганическими материалами, из глинистых минералов, входящих в его состав, для повышения скорости десорбирования метана из упомянутого отложения посредством нагнетания водного раствора окислителя, включающего, как минимум, один окислитель, в упомянутое отложение с последующей добычей метана из упомянутого отложения с повышенной скоростью. К числу подходящих окислителей относятся пероксид, озон, кислород, диоксид хлора, гипохлорид натрия, водорастворимые соли гипохлористой кислоты, перхлорат, хлорат, персульфат, перборат, перкарбонат, перманганат, нитрат, а также их сочетания.
