Abstract

Спосіб відноситься до видобутку метану з вугільного відкладення. В тілі відкладення бурять щонайменше одну видобувальну і щонайменше одну нагнітальну свердловини. Частину отриманого з вугільного відкладення метану направляють в зону формування синтез-газу, де утворюється суміш окислу вуглецю і водню. Основну частину цієї суміші направляють в зону синтезу вуглеводнів. Окисел вуглецю і водень утворюють суміш більш важких вуглеводнів, що містять більше одного атома вуглецю в молекулі, і залишковий газ, що містить азот і двоокис вуглецю. Потік вуглеводнів одержують відокремленням основної частини залишкового газу від згаданих вуглеводнів. Стискають частину залишкового газу до тиску, придатного для нагнітання, і направляють його у вугільне відкладення. Метан може бути отриманий від одиничної свердловини або від множини свердловин, використовуваних для циклічного відкачування. Спосіб сприяє збільшенню видобутку метану з вугільного відкладення.
