CYCLIC PROCEDURE OF CARBON UNDERGROUND GASIFICATION |
摘要 |
FIELD: oil and gas production. ^ SUBSTANCE: cyclic procedure of underground carbon gasification consists in drilling blow 2 and gas withdrawing 3 boreholes to coal bed 1. Further, the procedure consists in connecting boreholes along the bed by hydro-break and in creating zone of synthesis 17, in igniting bed 1 at depression of the blow borehole and in alternate supply of air and water into bed 1 via blow hole 2 for heating bed 1 to temperature 1600 K. Upon termination of air supply pipe 4 perforated on its end with tip 6 for supply of water and CaO is introduced by pressing into blow hole 2 and into de-gassed space of coal bed 1. The cycle terminates when temperature in synthesis zone 17 reaches 700 K. Fractures of hydraulic break are filled with coarse-grained sand. ^ EFFECT: raised efficiency of combustible gases production process. ^ 1 dwg |
