In order to achieve efficient and convenient acquisition of various submarine formation samples in marine geological drilling， mud static pressure piston wireline coring tools， marine sand wireline coring tools and hydraulic percussion wireline coring tools were designed， and tested in the South China Sea. The test results showed that the mud static pressure piston wireline coring tools can effectively reduce disturbance of the sample with the in-situ structure relatively maintained. The marine sand coring tools and the hydraulic percussive coring tools had higher recovery in the silt and sand layers， which was better than the specification and can meet the drilling requirements.
