聚乙烯唑啉作为水合物抑制剂的应用
摘要：
本发明公开了一种具有良好生物降解性的水合物抑制剂。本发明新型水合物抑制剂是聚乙烯唑啉(PEO)，并可按照现有技术标准，与电解质、可溶性醇类等混合使用。所述水合物抑制剂使用压力为1.5～25MPa，温度为-20～25℃。本发明抑制剂能够克服现有技术缺点，以低浓度混合，注入生产或输送的石油流体中，降低水合物成核生长速度，具有适用性广，良好的生物降解性等特点。
摘要（英）：

The invention discloses a hydrate inhibitor with good biodegradability. The novel hydrate inhibitor disclosed by the invention is polyethylene oxazoline (PEO) and can be mixed with electrolyte, soluble alcohol and the like for use according to the exiting technical standard. The hydrate inhibitor is used under the pressure of 1.5-25 MPa at the temperature of minus 20-25 DEG C. By using the hydrate inhibitor, the defects of the prior art can be overcome; the hydrate inhibitor is mixed with other substances at a low concentration to be introduced into produced or transported petroleum fluid, and nucleate growth speed of the hydrate inhibitor is reduced; and the hydrate inhibitor has the characteristics of wide applicability, good biodegrability and the like.
