Embodiment 1

[0030] Example 1: The thin coal seam above the storage point is the target formation

[0031] In a certain place, carbon dioxide is stored in a coal seam 1000m underground. Through ground monitoring, it was found that CO 2 Leakage, escape to the surface. The ABAQUS software extended finite element method is used to determine that the leakage path is mainly micro-cracks, combined with ground monitoring, the scope of leakage and escape is determined.

[0032] The thin coal seam with a depth of 500m above the storage point was selected as the target stratum, and the straw biological liquefaction liquid was selected as the external hydrogen source. Injection wells and production wells are arranged in this coal seam with a distance of 350m, located in CO 2 Both sides of the leak path.

[0033] The biological bacteria solution is a mixture of bacteria enriched from coalbed methane produced water, including hydrogenotrophic methanogens, α-proteobacteria, β-proteobacteria, hydroge...

Abstract

A deep strata storage method for CO 2 The biological escape prevention method belongs to the field of carbon dioxide emission reduction and can solve the problem of easy leakage and escape of carbon dioxide, including the following steps: collecting CO 2 Storage point geological data, clear CO 2 Leakage path; arrange injection wells and production wells in the stratum above the storage point; detect whether the total amount of hydrogen sources in the stratum meets the requirements of CO 2 Bioconversion requirements; inject biofluids and hydrogen-rich organics into selected formations through injection wells; monitor methane and CO in selected formations in real time 2 Content, regular detection of microbial community composition; evaluation of stored CO 2 The degree of leakage and biotransformation, and adjust the structure of the flora; the CH produced by the production well 4 . The present invention utilizes microorganisms to convert CO 2 The ability to leak CO above the storage layer 2 converted to CH 4 or organic matter, thus preventing CO 2 escape, while also leaking CO 2 The utilization of resources has the significance of environmental protection and energy.

Description

technical field [0001] The invention belongs to the technical field of carbon dioxide emission reduction, and in particular relates to a deep formation sequestration CO 2 Biocontainment methods. Background technique [0002] Greenhouse gas emissions, mainly carbon dioxide, have caused global warming. Global warming has brought many impacts on the earth's ecosystem and the sustainable development of human society, such as melting ice caps, extreme weather and rising sea levels, which will endanger human life and survival. Therefore, the research and development and promotion of carbon dioxide emission reduction technology has become one of the important tasks of all countries in the world. [0003] So far, the measures to reduce carbon dioxide emissions mainly include: improving energy utilization efficiency; protecting the ecological environment and increasing vegetation area; vigorously promoting various clean energy sources, such as wind energy; implementing carbon dioxi...
