Example Embodiment

[0035] Embodiment 1: It is the basic embodiment of the production method of carbon-free marine oil and gas energy of the present invention. As attached figure 1 , 5 The method for producing carbon-free marine oil and gas energy includes the following steps: marine oil and gas exploitation, seawater scrubbing and desulfurization of flue gas produced by marine oil and gas energy production equipment including ocean oil and gas exploitation, and carbon and nitrogen-containing smoke after desulfurization The gas is reinjected into the seabed oil and gas field; the carbon and nitrogen-containing flue gas is carbon dioxide, or a mixture of carbon dioxide and nitrogen; the carbon and nitrogen-containing flue gas is reinjected into the seabed oil and gas field is to use the flue gas as a recovery reinjection The gas is pressurized and reinjected into the seabed oil and gas field 1.1 to store carbon dioxide and improve oil and gas recovery. The offshore oil and gas energy production eq...

Example Embodiment

[0036] Example 2: It is a further example based on Example 1. As attached figure 2 , 5 The method for producing carbon-free marine oil and gas energy of the present invention includes the steps of using oil and gas for marine oil power generation and external transmission of electric energy; the marine oil and gas energy production equipment used for marine oil and gas power generation is built near the marine oil and gas exploitation facilities. Marine oil-fired power plant using oil and gas 2.

[0037] The technical solutions, principles, and effects of the foregoing method embodiments 1 and 2 are further described as follows:

[0038] The reinjection of nitrogen and carbon dioxide gas into oil and gas fields is called "nitrogen flooding" or "CO 2 Flooding" or "nitrogen and CO 2 "Hybrid flooding" oil and gas production technology. The flue gas produced by oil and gas exploration facilities, marine oil power plants and other marine oil and gas energy production equipment is mainl...

Example Embodiment

[0044] Example 3: It is a further example based on Example 2, as attached figure 2 , 4 As shown, in the production method of carbon-free marine oil and gas energy, the method of burning oil and gas in the marine oil-fired power plant 2 is to blow in oxygen to increase the carbon dioxide content and reduce the nitrogen content. In the case of blowing oxygen into the combustion device of the marine oil-fired power plant 2, the concentration of carbon dioxide in the generated flue gas can exceed 90%, which is beneficial to increase the carbon dioxide storage capacity.

Abstract

The invention relates to a carbon-emission-free marine oil gas energy production method and device. The method includes the steps that marine oil gas is produced, flue gas produced by the marine oil gas energy production device is subjected to seawater washing desulfurization, and the carbon-containing nitrogen-containing flue gas is re-injected into seabed oil and gas field. The device comprises a marine oil gas exploitation facility, a seawater washing desulfurization device, a carbon-containing nitrogen-containing flue gas pressurizing and reinjection device, a marine fuel power plant erected beside the marine oil gas exploitation facility and used for supplying power to a power grid, and an oil gas processing plant. The method and device have the advantages that carbon dioxide generated in the marine oil gas energy production process is economically and safely stored, and the oil gas recovery rate, namely the ratio of the produced quantity of oil gas to the reserve of the marine oil and gas field, is increased. A feasible approach for fossil fuel carbon-emission-free clean utilization is provided, and a brand new economic and efficient solution is added for achieving the 2-DEG C climate goal (2DS) of the international energy agency (IEA) and the all-process technology.

Description

technical field [0001] The invention relates to a production method and equipment for carbon-free marine oil and gas energy, which is applicable to the energy production of marine oil and gas exploitation, power generation and electric energy conversion and transportation for carbon dioxide capture and storage (CCS) in the whole process, and belongs to the technical field of clean energy and marine engineering . Background technique [0002] Carbon capture and storage (CCS) technology to reduce greenhouse gas emissions from fossil fuels is the main measure to achieve the International Energy Agency's (IEA) 2°C climate goal (2DS) (the global long-term average temperature rise is limited to below 2°C), but The long-term problems of capture, transportation and storage and the overall high cost and additional carbon emissions, as well as the long-term safety problems of large-scale underground storage, limit the promotion and implementation of the whole process CCS technology....
