摘要
在纵横弯曲法基本理论的基础上,进一步发展了变截面钻具组合的受力变形分析。在此基础上开发出配套软件系统,对变截面钻具组合的力学特性作了详细的分析,并通过现场数据验证了该理论的正确性。
Abstract
On the basis of beam and column method,deformations of the BHA of veriable cross section are analyzed and the analyzing software system has been developed.The mechanics characters have been analyzed to the BHA of veriable cross section and theory is proven through the data on case.
