Abstract: In view of the natural gas hydrate reservoir environment and relying on the research on the geological survey pro-ject"the design and technical study on in-situ drilling and sampling equipments for the water formations", pressure-temper-ature core sampler for ocean was developed.On the basis of laboratory test, functional marine experiment was made on the developed drilling tools in shallow water and deep water successively.After the improvement, the functional test of pres-sure-temperature core sampler was made in 1392m deep sea with success, which lays a solid foundation for the ocean explo-ration and sampling of natural gas hydrate in China.
