Supercritical carbon dioxide completion fluid

The invention belongs to the technical field of petroleum and natural gas well completion, and relates to a supercritical carbon dioxide completion fluid. The supercritical carbon dioxide completion fluid is prepared by mixing a preflush spacer fluid, a supercritical carbon dioxide flushing solution and a post-flush spacer fluid according to a volume ratio of 2-5:100:1-5. When the supercritical carbon dioxide completion fluid is used, the supercritical carbon dioxide flushing solution and a cementing slurry are prepared on the ground, the preflush spacer fluid and the post-flush spacer fluid are prepared, the preflush spacer fluid, the supercritical carbon dioxide flushing solution, the post-flush spacer fluid and the cementing slurry are sequentially pumped into a well head through a present fluid device in order to flush, the cementing slurry solidifies after the flushing, and an alkaline substance is injected from an annulus to remove carbon dioxide in the supercritical carbon dioxide flushing solution in order to prevent pollution of carbon dioxide to atmosphere and corrosion of carbon dioxide to bushings. The supercritical carbon dioxide completion fluid has the advantages of easily available raw materials, scientific principle, use convenience, good cementing effect, low cost, effective reduction of the thickness of mud cakes, and improvement of the cleanliness and roughness of the mud cakes.
