| Abstract: | The directional cementing techniques areexpounded from casing string design, medial casingdesign, selection of casing accessories, pad fluids design, slurry design and borehole preparations. Morethan 60 directional wells have been completed in Jiangsu exploratory area. The certification of cementingquality is 100N, optimization over 85%, which indicates MGMR has controlled the series of directionalcementing techniques. including multipurpose longopen hole (> 3000m), highly-inclined well (> 42℃)and long reach well (>700m). |
