摘要： An apparatus for combined coring and drilling in a wellbore includes a core drilling assembly with a coring drill head, an outer tubing for conveying forces to the drill head, an inner tubing with an upper end connected to a bearing assembly, and a lower end adapted for receiving a core sample. The apparatus further includes: a lifting device, for controlling the position of the inner tubing along the longitudinal axis of the core drilling assembly, that is connected to or is arranged as a part of the bearing assembly; closure elements with embedded cutting implements for cutting core sample; and one or more controller device(s) for controlling activation and deactivation of the closure elements. The closure elements are connected to the core drilling assembly at the lower end and below the opening of the inner tubing such that, when in an open position enables core sample to enter the inner tubing, and when in a closed position prevents core material from entering the inner tubing and then cut core material letting it exit to the borehole annulus via drill head openings provided in the wall of the coring drill head.

摘要： Core sample catchers for use with coring tools for obtaining core samples from subterranean formations may include at least one flap catcher member configured to be movably coupled to an inner barrel of the coring tool and configured to move between an open position and a closed position. A piston member including a central bore may be disposed in a passageway extending through the inner barrel. The piston member may be configured to move between a first position and a second position, the piston member configured to retain the at least one flap catcher member in the open position when the piston member is in the first position, and allow flap catcher member to move into the closed position when the piston member is in the second position.

摘要： The present disclosure discloses a core holding system, comprising: a sleeve in which a cavity capable of accommodating a core is formed; an adjustment plug set comprising a plurality of adjustment plugs having grooves of different diameters, wherein any one of the adjustment plugs is dismountably connectable to the sleeve, and when the adjustment plug is mounted on the sleeve, an end of the adjustment plug having the groove is insertable into the sleeve while abutting against the core; a heating module provided to sheathe the sleeve; and a thermal insulation module provided to sheathe the heating module. Before the core is held, the operator may select a matched adjustment plug from the adjustment plug set according to a diameter of a core to be held, so that a diameter of the groove of the adjustment plug is matched with a diameter of an end of the core, thereby ensuring that the end of the core can be engaged in the groove, thus ensuring that the core holding system can stably and tightly engage the core, and preventing the held core from being shifted or loosened.

摘要： A device to be used during geological exploration for obtaining a specimen of soil lying beneath the surface of the earth. The device is to be dropped from the air, e.g., from a hovering helicopter, and the nose thereof allowed to penetrate the surface of the earth. A sample is collected in the device and the device is retrieved into the hovering helicopter by means of a cable and a winch. The apparatus includes a hollow tubular body having a flange stop-collar approximately midway along the body to limit its penetration into the earth and fins at the tail to aerodynamically guide it during its fall to earth. The front or nose end of the body is provided with spreadable guarding jaws which are closed during impact and which are formed in an arrowhead shape to enhance penetration of the earth. A relatively heavy interior body fits within the hollow body and includes an open front portion to receive a sample. The interior body is releasably retained in a position near the tail of the hollow body by a spring urged pin. After the device is dropped from a helicopter, the pointed guarding jaws of the hollow body penetrate the earth on impact, penetration of the hollow body being continued until the stop collar brings the device to a sudden halt. Inertia of the interior body causes it to be pulled loose from the spring urged pin, the momentum of this body causing it to move through the hollow body and to spread the guarding jaws at the nose end beneath the surface. The interior body continues to move downwardly and passes partly out of the hollow body so that the open front portion thereof penetrates subsurface soil and collects a sample. Retrieval of the cable causes the interior body to withdraw into the hollow body and permits the entire device to be returned to the helicopter.
