Our company's construction data from the Great Wall Drilling Company shows that this well had a fluid volume of 1349.6 cubic meters and a sand volume of 155.0 cubic meters injected into the well. The liquid nitrogen injection volume was 0 cubic meters. The well was opened at 17:15, with a 6mm nozzle for blowout, pressure at 18.5, and ignition failed to burn. At 17:25, using an 8mm nozzle, pressure was at 15, and ignition failed to burn. At 17:45, using a 10mm nozzle, pressure was at 11.5, and ignition failed to burn. At 18:30, using a 10mm nozzle, pressure was at 7, ignition succeeded, with a flame of 0.2-0.5 meters. At 18:40, using a 10+10mm nozzle, pressure was at 7, flame was 0.2-0.5 meters. At 18:50, the nozzle was opened wide, pressure was at 4, flame was 0.5 meters. From 18:50 to 5:30, the nozzle was opened wide, pressure was at 0, flame grew to 4-6 meters. From 5:30 to 6:00, the well was shut in, pressure was at 0-5, stage backflow volume was 810 cubic meters, cumulative backflow volume was 810 cubic meters, backflow rate was 60.02%, chlorine content was 6725. This fully demonstrates on the construction site that our product is resistant to high temperatures, shear-resistant, low dosage, and high efficiency!
