Brief introduction
Hydraulic sand jetting perforator fracturing is well stimulation which combined of perforating, fracturing andisolation. High speed liquid that from specialized jetting tools could shoot through casing, rock and shape hole.
Bottom hole pressure is increased by annular fluid infusion, which exceed stratum fracturing pressure and
crack layer. This method has advantage of deeper than ordinary perforating, aperture is larger and less hurt
to stratum.
Application
• Apply to low permeability reservoir, thin reservoir and edge/bottom water reservoir;
• Suitable for vertical well (casing, liner and openhole), horizontal well and multistage perforating fracturing
operation.
