A kind of composite hydrate antipolymerization agent and preparation method thereof

Abstract

The invention provides a compounded hydrate anti-agglomerant and a preparation method thereof. The method comprises the following steps: selecting a plant containing a biosurfaetant, extracting plantextract and segmenting the plant extract according to the polarity difference to determine an effective substance polarity segment; eluting to obtain an active part, and carrying out analysis and component deduction on the active part; compounding the deduced active ingredients to obtain the compounded hydrate anti-agglomerant. By using the preparation method of the compounded hydrate anti-agglomerant, provided by the invention, the active ingredients with an anti-agglomerating effect in the plant containing the biosurfaetant can be analyzed, detected and determined accurately and effectively,and the problems of blind screening and the like of the active ingredients of the compounded hydrate anti-agglomerant are solved. The compounded hydrate anti-agglomerant prepared by the method belongs to a plant extraction type hydrate anti-agglomerant, has the characteristics of pure nature, good water solubility, easiness in biodegradation and the like, and can be applied to hydrate anti-agglomeration of oil and gas pipelines in deep sea.

Description

technical field [0001] The invention belongs to the technical field of hydrate antipolymerization agents, and relates to a composite hydrate antipolymerization agent and a preparation method thereof. Background technique [0002] Gas hydrates are water and methane, ethane, CO 2 and H 2 Non-stoichiometric cage-like crystalline substances formed by small molecular gases such as S under low temperature and high pressure conditions. Hydrates are easily generated in natural gas / crude oil mixed pipelines to block pipelines and equipment. For a long time, oil and gas production and transportation departments have spent a lot of money on hydrate prevention and control. Today, as oil and gas resources are increasingly scarce, the focus of oil and gas development is increasingly shifting to the deep sea. The temperature and pressure conditions in the deep sea oil-gas-water three-phase mixed pipeline are very suitable for the formation of hydrates, and the problem of hydrates is part...
