Abstract

The invention discloses a mine downhole oil-gas storage cavern which comprises a storage carven body and an oil-gas conveying pipeline assembly. The storage carven body comprises a storage carven bodybottom component, a reinforcing top plate and a layer of storage carven body middle component or a plurality of layers of storage carven body middle components which are fixedly connected up and down. The bottom of the storage carven body middle component at the bottom layer is fixedly connected with the top of a storage carven body bottom component, and the reinforcing top plate is fixedly connected to the top of the storage carven body middle component at the top layer. The oil-gas conveying pipeline assembly comprises an oil-gas input pipeline and an oil-gas output pipeline, an oil-gas input control valve is arranged on the oil-gas input pipeline, and an oil-gas output control valve is arranged on the oil-gas output pipeline. The invention further discloses a construction method of themine downhole oil-gas storage cavern. The mine downhole oil-gas storage cavern is stable in structure, high in strength, good in sealing performance and good in anti-seepage performance, enables a mine goaf to be reasonably utilized, and provides new thoughts for exploration of energy storage caverns.

Description

technical field [0001] The invention belongs to the technical field of mining and energy storage, and in particular relates to an underground oil and gas reserve in a mine and a construction method thereof. Background technique [0002] In the mining process of metal mineral resources, the goaf has the characteristics of huge spatial scale, complex geological environment and serious safety hazards. At present, the treatment measures for gobs in metal mines mainly include: treatment of surrounding rock collapse, filling treatment, permanent pillar treatment, sealing treatment and other methods. Permanently leaving ore pillars is not conducive to efficient mining of resources, and the treatment of collapsed surrounding rocks is not conducive to the protection of the surface environment, and the closed treatment has great safety hazards. Filling is an effective technical method to achieve safe, clean and efficient mining of ore deposits, and it plays a dual role in protecting ...
