System and method for injecting a treatment fluid into a wellbore and a treatment fluid injection valve

A treatment fluid injection valve for injecting a treatment fluid into a wellbore, the treatment fluid injection valve comprising:

• a tubular housing comprising a housing axial fluid passage, a fluid inlet being in fluid communication with the housing axial fluid passage, and a lateral fluid outlet;
• a sleeve member having a sleeve axial fluid passage and at least one lateral fluid opening, the sleeve member being fixedly arranged within the tubular housing, wherein the sleeve axial fluid passage is aligned with the housing axial fluid passage, and wherein the at least one lateral fluid opening is aligned with the lateral fluid outlet;
• and
• a piston member being moveably disposed within the sleeve axial fluid passage between a closed position and an open position, wherein the piston member in the closed position blocks treatment fluid flow from the housing axial fluid passage toward the sleeve axial fluid passage, and wherein the piston member in the open position permits treatment fluid flow from the fluid inlet through the housing axial fluid passage, the sleeve axial fluid passage, and the at least one lateral fluid opening in the sleeve member toward the lateral fluid outlet of the tubular housing;
• wherein the lateral fluid opening in the sleeve member defines an adjustable flow area, wherein the adjustable flow area is adjustable by controlling the position of the piston member relative to the lateral fluid opening to a partially open position between the closed position and the open position.
