The hydrocarbon accumulation has selectivity on genetic type of sand body, while oil and gas enrichment is controlled by favorable sedimentary facies belt and reservoir facies belt.
A kind of hydrocarbon-oil desulfuration agent contains, on the catalyst-weight basis, 15-60% phosphorus-modified and rare-earth-contained Y type zeolite, 10-60% inorganic oxide, and 0-75% clay;
