Abstract
Natural gas hydrate is a kind of ice-like crystal compound, which is usually formed under the environmental conditions of coexistence of gas and water with high pressure and low temperature. The hydrate generated in the pipeline usually causes blockage, which will bring serious safety problems and economic losses to the process of natural gas exploitation and transportation. Oil and gas gathering and transportation pipelines in China are hundreds of thousands of kilometers long, and there is a common risk of gas hydrate blockage, so it is urgent to effectively ensure flow safety and reduce the risk of blockage. In this paper, a kind of compound hydrate inhibitor with different ratio was evaluated from inhibition effect, hydrate formation rate and induction time. A good ratio was obtained by simulating the actual production condition in gas pipeline through the tube rocking apparatus. It can provide reference for inhibiting hydrate formation in natural gas pipeline.
