摘　　要：本文基于中石化西北油田的井下油管工况需求,进行了复合材料油管的可行性研究工作。主要进行了耐高温复合材料树脂及单向板的力学性能研究,结合井下油管实际受力情况进行样件的内压、扭转及轴拉试验。研究表明,复合材料油管可以满足井下高温及力学环境要求。Based on the requirements of downhole tubing conditions in Sinopec Northwest Oilfield,this paper conducted a feasibility study of composite tubing. The mechanical properties of high temperature resistant composite resins and unidirectional plates are mainly studied. The internal pressure,torsion and axial tension tests of the samples are carried out in combination with the actual force of downhole tubing. Research shows that composite tubing can meet the requirements of downhole high temperature and mechanical environment.
