| Abstract: | The perforation tunnel cleaning tool mainly includes a hydraulic oscillator which may generate pressure surge and two sound filters-upper one and bottom one, pressure surge generated by hydraulic oscillator may create circulating stress in the wall of perforations, therefore to remove the skin damaged and increase well productivity. The upper and bottom sound filters may limit propagation direction of pressure surge, forcing it concentrated on the perforated interval. This paper introduces the structure, working principle and operating procedure of the tool. Subject heading |
