Problems solved by technology

However, if Figure 7 , Figure 8 As shown, due to the constraints of the existing decentralized utilization of fossil fuels, the fossil fuel mining sources, carbon emission sources, and sequestration sinks involved in CCS technology have long been far away from each other. The problem of additional carbon emissions in the link and the overall existence, as well as the long-term safety of underground carbon storage are difficult to overcome, resulting in the long-term failure of CCS technology to be well realized, especially the application of the whole process is not scaled

Embodiment 1

[0034] Embodiment 1: It is the basic embodiment of the carbon emission-free combined oil and gas power generation method of the present invention. as attached figure 1 , 3 As shown in , 6, the carbon-free combined oil and gas power generation method, the steps include: extracting oil and gas from the oil and gas field 1.3, burning the exploited oil and gas to generate electricity on the spot, and reinjecting the carbon and nitrogen-containing flue gas generated by the combustion and generating electricity back into the oil and gas field 1.3 to Sequestering carbon dioxide and enhancing oil and gas recovery; said oil and gas extraction from oil and gas fields 1.3 is to use oil and gas extraction facilities 1 to extract oil and / or natural gas from oil fields and / or gas fields through extraction / reinjection wells; said on-site combustion power generation, The electric energy is generated by the oil and gas exploited by the on-site oil and gas extraction facility 1 through the on...

Embodiment 2

[0035] Embodiment 2: is a further embodiment on the basis of Embodiment 1. as attached figure 2 , 4 As shown in 5 and 5, the carbon emission-free combined oil-gas power generation method of the present invention, the step of in-situ combustion power generation also includes oxygen-enriched combustion in which oxygen is blown into the combustion process to increase the purity of carbon dioxide in the flue gas generated by combustion. The carbon dioxide concentration in the flue gas produced in this way can exceed 90%, which is conducive to increasing the carbon dioxide sequestration capacity.

Embodiment 3

[0036] Embodiment 3: is a further embodiment on the basis of Embodiment 1. The on-site re-injection of the carbon- and nitrogen-containing flue gas into the oil-gas field is to transport the carbon- and nitrogen-containing flue gas through corrosion-resistant pipeline facilities to be pressurized and re-injected into the oil-gas field 1.3.

[0037]CO2 Injection into Oil and Gas Fields 1.3 for Enhanced Oil and Gas Recovery CO 2 -EOR methods have been used as early as the 1960s and 1970s, but it is difficult to increase the production and storage of oil and gas by reducing carbon dioxide emitted by humans. The reason is that the flue gas produced by fossil fuels is mainly composed of 80-85 % nitrogen, 15-20% carbon dioxide, and a small amount of corrosive sulfur dioxide. However, the existing oil and gas resource utilization method is a full-process dispersion method of single mining, single refining, and single use. Corrosion problems, at least there is an insurmountable econo...

Abstract

The invention relates to a carbon-emission-free oil gas power-generating method and device and provides a carbon-emission-free oil gas resource utilization mode for in-place oil gas exploitation, in-place combustion for power generation and in-place reinjection for sealed carbon dioxide storage and far-end electric energy utilization, namely a complete-flow large-scale CCS technology. The carbon-emission-free oil gas power-generating method and the device enable an oil gas exploitation source, a carbon emission source and a sealed storage source to have zero distance, accordingly eliminate carbon trapping, transportation and sealed storage links and overall additional carbon emission and enable primary energy to be free of carbon emission and to be converted into clean secondary energy. The carbon-emission-free oil gas power-generating method and the device have the advantages that large-scale emission reduction and safe sealed fossil fuel storage are achieved, produced carbon dioxide is utilized, meanwhile the actual exploitation quantity of oil gas resources is increased, a feasible way for carbon-emission-free clean fossil fuel utilization is opened compared with theoretical reserves, and a breakthrough clean energy solution is added for achieving the global climate purpose of 2 DEG C or even 1.5 DEG C.

Description

technical field [0001] The carbon emission-free combined oil-gas power generation method and equipment of the present invention belong to the technical field of clean energy. Background technique [0002] Achieving the climate goal of limiting the global long-term average temperature rise to below 2°C (2DS) has a bearing on the global environment and the destiny of mankind. One of the keys to achieving the goal is to realize the large-scale application of the whole process of CCS (carbon capture and storage) technology that reduces carbon emissions from fossil fuels as soon as possible. However, if Figure 7 , Figure 8 As shown, due to the constraints of the existing decentralized utilization of fossil fuels, the fossil fuel mining sources, carbon emission sources, and sequestration sinks involved in CCS technology have long been far away from each other. The problem of additional carbon emissions in the link and the whole, as well as the long-term safety of underground...
