Coring device, core storage mechanism and coring method

The invention discloses a coring device, a core storage mechanism and a coring method. The core storage mechanism comprises a wheel disc, a power source and a bracket, wherein N inserting holes are formed in the wheel disc, wherein N is a positive integer which is larger than or equal to 2; spare coring bits are arranged in the N-1 inserting holes; the rest inserting holes are matched with a coring bit of a coring motor; the power source can provide a rotating force for the rotation of the wheel disc; under the driving of the power source, the wheel disc operates according to (360/N)/time; andthe bracket is connected with the wheel disc through the bracket and can drive the wheel disc to move up and down. According to the coring device, the core storage mechanism and the coring method, anobtained rock core sample can be well protected, and the success rate of this type of formation coring can be increased when unstratified rock unconsolidated formation with narrower formation is cored. 本发明公开了种取芯装置、储心机构及取芯方法，该
