Deepwater petroleum drilling and production technology

In China, energy resources consumption increases considerably, but the energy supply is insuficient, so it is necessary tocarry out exploration and development in deepwater. This paper introduces the development of the drilling technology offshore abroad, shows the dificulties in deepwater drilling and production in China, summarizes the features of ive sorts of drilling and production plat- forms, i.e., semi-submerged platforms, deepwater drilling vessels, loating production storage ofloading devices, tension leg platforms and spars, and also gives some advices in selecting platforms, generalizes four development modes in deepwater. It is considered that the “FDPP+WHXT+FPSO/FSO” mode is reasonable according to the actual development environment in deepwater. At last, the develop- ment trend of the drilling and production technology in deepwater is prospected---large-scale, advanced, combined. Combustible ice will become a new focus. It is an inevitable choice to learn from foreign advanced technologies and follow the path of self-development.
