套管防磨技术在西南深井中的应用研究

Study of Casing Wear Prevention Technology Application in Deep Well in Southwest China

通过开展影响套管磨损主要因素的研究,制定了适合套管防磨方案与施工措施,提出旨在减少套管磨损的一系列主动防磨、被动防磨等技术,形成了一套有效减少深井套管磨损配套技术方案。现场应用表明:大幅度降低深井套管磨损程度,为今后深井套管防磨、减磨方案制定与具体施工提供技术借鉴。

Through the study of main factors of the influence of casing wear, the formulation of suitable casing wear prevention scheme and construction measures, proposed to reduce casing wear a series of active wear, passive wear technology, has formed a set of effective reduction of deep well easing wear matching plan. Through the construction practice, greatly reduce the deep well casing wear degree, for the future of casing wear away wear prevention plan and concrete construction to provide certain reference to the corresponding technology.
