Abstract

The present invention relates to a compound hydrate anti-aggregation agent composition and uses thereof. A purpose of the present invention is mainly to solve the problem of easy environment pollution, poor aggregation resistance and high consumption in the prior art. The technical scheme of the present invention comprises a compound hydrate anti-aggregation agent composition and uses thereof, wherein an oil-water emulsifier, a hydrate particle anti-aggregation agent, a hydrate particle dispersant and a synergist are compounded according to a mass ratio of 0.1-5:0.1-10:0.1-10:0.1-10 to obtain the compound hydrate anti-aggregation agent composition. With the technical scheme of the present invention, the problem in the prior art is well solved. The compound hydrate anti-aggregation agent composition of the present invention can be used for oil and gas transportation.

Description

technical field [0001] The invention relates to a composite hydrate antipolymerization agent composition and its application. Background technique [0002] Water molecules form polyhedral cage-shaped cavities at a certain temperature and pressure through hydrogen bonding, and these cavities can surround certain guest molecules (such as H 2 , N 2 , CO 2 、CH 4 、C 2 h 6 and C 3 h 8 etc.) wrapped in polyhedrons to form ice-like crystalline substances, commonly known as combustible ice. In oil-gas-water multiphase mixed transportation pipelines, especially during deep sea drilling, hydrate particles are easily formed, and then aggregate and grow, causing flow obstacles in wellbore or pipelines and affecting oil and gas production efficiency. Therefore, the research on gas hydrate prevention and control technology has attracted the attention of the oil and gas industry. [0003] Dehydration and pipeline heating are two methods traditionally used to solve the problem of hy...
