| Abstract:During the coring of loose and soft formation in the subsea and continental water region, there are many difficulties such as poor quality of core and low core recovery. The hydraulic pressure shear coring tool was designed to solve these problems. The paper introduced its design principles, configuration features and the laboratory test effect. |
