deviation angle
8.On the basis of a series of plane cascade wind tunnel test results the aerodynamic characteristics of axial-flow compressor intlet guide vanes with a variable trailing edge have been determined. As a result, ascertained is the necessary correction to be applied to the deviation angle of the variable trailing edge inlet guide vane when calculated as per Carter formula and also its proper application range.
9.In order to develop the low production and low permeability oilfields, four slim hole cluster wells were drilled on one platform in Jinn Oilfield, with the diameters of 152. 4mm each, well depths of 1729. 47- 1855. 53m, maximum deviation angle of 42°, and maximum lateral displacement of 514m. . Its cost was reduced by 19. 1 % in comparison with the conventional wellbore.
