摘  要:综述论题如下。前言:油田结垢原因、类型、对生产的影响及防垢方法分类(物理、化学、工艺方法)。①油田用防垢剂概述:有机膦酸类,聚合物类。②防垢机理简述。③防垢剂投放方法,特别是近井地层挤注法及其工艺。④挤注技术应用实例,包括:英国北海Miller油田(钡锶垢);挪威北海Asgard油田(钙垢),Heidrum油田(钡锶垢);沙特阿拉伯H、Z、Ghawar油田(钙垢);中国河南油田(碳酸钙垢);长庆油田(碳酸钙/硫酸钙垢);胜利油田(高温、钙垢)及江苏油田。A comprehensive review on the subject with following topics. Introductory part: the reasons, types, and influences on oil production of oilfield scale precipitation and classification of various anti-scaling methods, physical, chemical and technological. O General description of organic phosphoric acids and acid salts and polymers as two principal types of oilfield scale inhibitors (OFSIs). (2) Concise introduction into scale inhibiting mechanisms. (3) Ways and techniques of applying OFSIs an scale inhibitor squeeze treatments (SISTs) on oil wells and treating technologies in particular. (4) Cases of SISTs in British North Sea miller oilfield (Ba/Sr scale), in Norwegian North Sea Asgard (Ca scale) and Heidrun (Ba/Se scale) oilfields, in Soudi Arabian H, Z, and Ghawar oilfields (Ca scale), in China's Henan oilfield (CaCO3 scale), Changqing oilfield (CaCO3/CaSO4 scale), Shengli HT oilfield (Ca scale), and Jiangsu oilfield.
