Rope diamond core drilling technology

Wireline diamond core drilling technology in China for more than 30 years of application history, has formed a relatively complete drilling processes and procedures. But the rope coring drill to maintain the original structure and the strength of the basic level , drill low intensity, short service life , operational reliability is poor, deep hole drilling accident rate , drill pipe break accidents have occurred , can not meet the mineral exploration rope core drilling needs. In order to meet future mineral exploration and development, narrowing the gap with foreign countries , we have a diamond coring drill string and rope  Instrumentation ball valve  for the study of its structure, size, thread and other aspects of the geometric parameters of depth theoretical analysis, mechanical model for simulation optimization , and strive to make our rope coring drill pipe design and application to achieve a high level. Statics using finite  Valve manifolds  , by means of the current international general finite element analysis software ANSYS rope coring drill to establish three-dimensional static finite element  2 way manifolds  model . Qualitative simulation drill pipe and fittings threaded in the working state of stress and strain distribution of such displacement field . Through structural statics study and explore the life of the main factors restricting the drill pipe . To contact the nonlinear finite element theory, the connecting thread for drill pipe joints for detailed theoretical analysis .
