【摘要】 随着钻井技术的进步,油套管的服役条件更加苛刻,按照API标准生产的油套管螺纹接头已经不能满足某些油气井的使用要求,因此特殊螺纹接头的应用范围不断扩大。我国开发特殊螺纹接头尚处于初级阶段。综述了我国特殊螺纹接头油套管的生产使用现状,指出了我国特殊螺纹接头使用和开发过程中需要解决的问题,并就特殊螺纹接头的开发提出了几点建议。更多还原

【Abstract】 Along with the progress of oil well drilling technology,the work conditions for oil tubing/casing are increasingly critical.In this case,API tubing /casing thread connections can no longer satisfy the requirements for some oil/gas wells,and therefore the application scope of the premium thread connections are being expanded.In China the development of such premium thread connection is right now at an initial stage.Summarized here in the paper is the situation of domestic production/application of tubing/casing with premium thread connection.The existing problems concerning domestic application and development of premium threads are discussed,and some proposals are made.更多还原
