| Zusammenfassung: | The invention provides a coring simulation experiment device. The coring simulation experiment device comprises a simulation shaft; the rock sample barrel is arranged at the bottom of the simulation wellbore, and the rock sample barrel is used for containing a sample of a simulation stratum; the drilling machine simulation mechanism is used for drilling; the drilling tool sealing mechanism is used for connecting the drilling machine simulation mechanism with the rock sample barrel in a sealing manner; the drilling fluid circulating mechanism is connected with the drilling machine simulation mechanism and can pressurize the interior of the drilling machine simulation mechanism; wherein the drilling machine simulation mechanism comprises a pressure-maintaining lifting mechanism which is used for lifting a rock core sample in a pressurized sealing state. All parts of the drilling machine simulation mechanism are connected in a sealed mode, and the drilling fluid circulation mechanism is connected with the drilli |
