Formations were unconsolidated and hole deviation Angle was high, so it was difficult to recover cores from this well.
由于地层疏松,该井井斜角较大等造成取心难度大。
Hole Angle should not exceed 15 degrees any where in the hole unless down hole geological conditions induce such deviation, such as acute fault intersections.
井斜角在井眼任何地方不应超过15度,除非井下地质条件引发了此种偏离,如严重的断层交叉。
The extended reach well has such characteristics as large horizontal displacement, great deviation Angle and long open hole interval.
大位移井具有长水平位移、大井斜角以及长裸眼段的特点。
