Описание: The 2-trip system of Perf – Wash – and Cement has huge upside in creating a large flow area over a large distance to increase the chance of a successful wash and remedial cement job. On each cycle of the Gator perforator – 4 perforations are made simultaneously at 90 deg phasing. The perforation profile creates slots that direct fluid flow in a circular pattern up the B-annulus. The Jack hammer (washing tool) uses pistons to push out against the casing I.D that drop along the perf profile to create a jack hammer force. This helps agitate any cement or debris behind the casing in the B-annulus. Without having to trip tools to surface cement can be pumped and squeezed into the recent perforated and washed Gator perforations.
