OPTIMIZING CHARGE PHASING OF A PERFORATING GUN |
摘要 |
A method includes arranging shaped charges (10) in a perforating gun (20) to produce perforation holes (50) in a helical pattern that is defined in part by a phase angle; and choosing four adjacent perforation holes (50a, 50b, 50c, 50d) to be created that are adjacent nearest neighbors. The distances are determined between three of the four adjacent perforation holes to be created. A standard deviation is minimized between the three adjacent perforation holes. The phase angle is set based on the minimization.
