description | The invention relates to a sulfur-containing natural gas hydrate inhibitor, which comprises the following ingredients in percentage by weight through being metered by the total weight percentage of 100 percent: 10 to 30 percent of dynamic hydrate inhibitors, 10 to 30 percent of surfactants, 2 to 5 percent of defoaming agents, 2 to 5 percent of corrosion inhibitors and 50 to 70 percent of organic solvents, wherein the dynamic hydrate inhibitors are N-vinylcaprolactam and 2-allylformamide-2-methyl sulfonate bipolymers with the weight-average molecular weight being 5000 to 20000 or N-vinyl pyrrolidone, N-vinylcaprolactam and 2-allylformamide-2-methyl sulfonate terpolymers with the weight-average molecular weight being 6000 to 30000. The hydrate inhibitor has a better inhibition effect on hydrates formed by high-content hydrogen sulfide natural gas and is applicable to the prevention of hydrate formation in a high-temperature and high-salt sulfur-containing natural gas integral conveying system, the blockage form |
