| Abstract: | The main task of geological exploration drilling is to obtain representative core samples reliably and accurately,however,it is very difficult to get high quality core samples with conventional drilling techniques in complex strata.A kind of new double barreled forced coring tools is introduced here,its working principle is discussed and its key mechanisms is analyzed,the main technical characteristics of the new coring tools are summarized.Drilling tests indicate that the new coring tools can obviously inc... |
