A rolling and sliding adaptive device for guiding and fixing a drill pipe includes a mounting platform, where the mounting platform is provided with a through hole for the drill pipe to pass through. Multiple rolling and sliding support mechanisms are arranged around the through hole. The rolling and sliding support mechanisms each include a support seat. The support seat is provided with a contact element telescopic and swingable on the support seat. A telescopic drive mechanism is provided between the contact element and the support seat. The contact elements on the multiple rolling and sliding support mechanisms form a funnel-shaped structure with a large upper part and a small lower part around the through hole. The rolling and sliding adaptive device is used on a deep in-situ high-fidelity coring calibration platform for accurate positioning of an assembly process of a multi-section drill pipe bin.

An internal blowout-prevention gas-retaining connector has a body mounted at the bottom of a drill pipe. The body includes a valve pipe section and a connecting pipe section arranged from top to bottom. The bottom of the valve pipe section is inserted into the top of the connecting pipe section. The blowout-prevention valve seat is provided at a bottom end of the valve pipe section while a blowout-prevention valve bonnet is provided on a bottom surface of the valve pipe section. The edge of the blowout-prevention valve bonnet is rotatably connected to a bottom surface edge of the valve pipe section. A torsion spring is provided on a bottom surface of the blowout-prevention valve bonnet. One end of the torsion spring is connected to the bottom surface of the blowout-prevention valve bonnet while the other end is connected to the inner wall of the connecting pipe section.

Disclosed is a continuous conduit apparatus based on guiding and injecting integrated mechanism, which comprises a straightening apparatus and a pair of sprocket and chain clamping assemblies. The pair of sprocket and chain clamping assemblies are configured to clamp the conduit and pull the conduit to go downwards a well or upwards a lifting direction. Between the pair of sprocket and chain clamping assemblies, a conduit guide channel applied for the conduit to passing through is formed. An inlet and an outlet of the conduit guide channel are not situated in a straight line, and the straightening apparatus are configured to straighten the conduit. Each of the two sprocket and chain clamping assemblies comprises a sprocket set, a chain, a plurality of clamping blocks mounted on the chain, and a pushing plate configured to press the clamping blocks.

Continuous conduit apparatus based on guiding and injecting integrated mechanism

Disclosed is a continuous conduit operation apparatus, which comprises a folding frame and a guiding and injecting integrated mechanism configured to pull the conduit to go downwards a well or upwards a lifting direction. The folding frame comprises a base, a mounting frame connected to the base in a movable connection, and a telescopic mechanism configured to rotate the mounting frame in a vertical plane around a position of the movable connection. One end of the telescopic mechanism is movably connected to the base, another end of the telescopic mechanism is movably connected to the mounting frame. The guiding and injecting integrated mechanism is arranged on the mounting frame. The present disclosure integrates the guiding function and the injection function to reduce the height of the apparatus and is suitable for operation environment with limited space and height.
