| Abstract: | For safe problems of narrow density window drilling, fine controlled pressure drilling system （MPD） was developed by western drilling. The MPD system pressure control principle was analyzed, the structure and key technology of MPD system were described, and the MPD system was tested in Xinjiang oilfield. The results show that the system can reaI-time monitor the drilling condition and can keep the bottom hole pressure smoothly in different working conditions which met the security complex formation drilling narrow density window needs. |
