Abstract: Present situation and developing current of deepwater drilling was analyzed in our country, and the fundamental performances which deepwater drilling fluids must possess were studied on the base of investigation. In order to deeply research on fundamental performances, hydrate generation and inhibition, circulation and wellbore stability of deepwater drilling fluids, new simulating experiment installation was developed on the basis of combination of theoretical derivation and practices. And the feasibility and parallelism of the instruments were inspected, it was showed that the new developed installations have a highly control accuracy and good parallelism, which can meet the needs of deepwater drilling, and provide references for deepwater drilling fluids research in laboratory in China.
