MPD_WELL(DOWNLOAD THE USB DEMO)

MPD_WELL apply to the drilling process, through the mud circulation rate, mud density, mud fluid compatibility, the ground slurry temperature, and wellbore annulus level geometric characteristics and other parameters to ensure that either a depth of underground wells designed for eye-safe stability tools.

MPD_WELL including the managed pressure (MPD) and under balanced drilling (UBD) design. UBD corresponds to maintain bottom hole pressure below formation pressure in order to avoid formation damage (reservoir), while the MPD is used for precise controling of borehole annulus pressure profile, focusing on drilling to solve the problem of leakage and collapse. MPD technology can optimize the use of drilling, reduce non-productive time and accidents, and reduce the drilling into the casing under the number of layers in order to achieve integrality, economic drilling of its key technology is to identify safe pressure window, control annulus pressure.
