| Abstract: | The appliance of The DTH reverse circulation drilling technology has special results in drilling complex strata.Rely on the CGS's projects,through field pilot production,Further physical study on the reverse circulation mechanics,the structure of hollow-through DTH and its assorted drilling tools is rationally optimized,which increases the adaptability of complex strata and improved the operative technique and processing method,as a result,this DTH reverse circulation drilling technique can be widely used. |
| Keywords: | run - through DTH continuous chip removal by reverse circulation complex strata |
