Abstract
An integrated logging instrument for coring and sampling includes a downhole main body and a ground system. The downhole main body is connected with the ground system through a long cable. The downhole main body includes a coring and sampling mechanism, a power mechanism and an energy storage mechanism. The coring and sampling mechanism includes a coring assembly for drilling cores and a pushing and setting assembly for downhole fixation. The power mechanism is arranged at an upper end of the coring and sampling mechanism, and includes a motor, a piston structure and a pump body. The piston structure and the pump body are respectively arranged at two output ends of the motor. The piston structure is arranged to provide suction power. The pump body is arranged to provide hydraulic power. The energy storage mechanism is arranged at a lower end of the coring and sampling mechanism.
