MPD Technology In Si Chuan Jin Qiu And Fu Shun Blocks

Shale gas mined from shale, through study of Jin Qiu and Fu Shun blocks reservoir characteristics, use the advantage of Managed Pressure Drilling to Implementation shale gas exploration, Based on the basic principles of the bottomhole pressure control, gives the corresponding MPD key parameters design method. In order to improve control precision, on the basis of the analysis of the conventional control method, the state-of-the-art model predictive control method was introduced to MPD bottomhole pressure control system in real time, an advanced bottom hole pressure real-time control model was established.Though using in QL-6、QL-32、ZT-19、ZT-2, And the field problems are analyzed, Summarize the control pressure drilling technique in the autumn the fushun block construction well statistical analysis, fully embodies the advantages of control pressure drilling technology.
