| Abstract: | In UBD process, the under-balanced condition can be achieved by two methods: the natural one or the artificial one. Four foreign gas injection methods and selection law of completion fluids are presented. When the completion fluids are optimized, the formation characteristic and drilling cases should be investigated, and close attention should be paid to problems such as hole stabilization, water bed , acidic gas and etc. . Surface control system and requirements for UBD technology are also given. |
