绳索取心钻杆螺纹锥度与强度关系及应力研究

Study of Relationship Between Wireline Drill Pipe Thread Taper and Strength and Its Stresses

通过一系列室内拉伸、扭转及光弹应力试验，研究了绳索取心钻杆螺纹锥度与强度的关系及其应力分布规律。

A study is put on the relationship between the thread taper and its strength,as well as the stressdistrtrbution law through a range of lab tensile,torsional and optical-elastic stresstests.
