Borodn D.S. Belsh Tyumen Branch of Khrstanovch Insttute of Theoretcal and Aled Mechancs SB RAS Tyumen Russan Federaton Tyumen State Unversty Tyumen Russan Federaton E-mal: bedeser@yandex.ru The aer formulates a roblem of njecton nto orous bed flled u n the ntal condton wth hydrate and as warm (wth the temerature hher than the ntal temerature of the bed as. A mathematcal model of non-sothermal as fltraton n case of as hydrate dssocaton s develoed to solve ths roblem. The artcle resents a soluton alorthm where an mlct dfference scheme a swee method and a method of smle nteraton are aled. The method for calculatn hydrate saturaton from several lmtn condtons s suested. It can be used for soluton of other hase-chane roblems also for multdmensonal Stefan roblems as well as roblems wth an extended hase transton zone. After that the roblem s consdered n one-dmensonal lane-arallel formulaton wth reard to requred ntal and boundary condtons for fndn a comutatonal soluton of a set of equatons descrbn ths model. At the end the aer resents the roblem calculaton results usn the suested method on the bass of whch the dstrbuton of arameter values for some tme ntervals are shown. In the erformed calculatons the reservor n the ntal condton s flled u wth methane and ts hydrate. Keywords: non-sothermal fltraton of as; as hydrate; numercal method; hase transton.
