Principle
With the large-scale development of unconventional reservoirs, the role of perforation has changed from "completion" to a precursor process for fracturing It is impossible for the perforator to be absolutely centered in the casing. Especially in the perforation and completion of horizontal Wells, due to the effect of gravity, the gun barrel is one-sided, which leads to the uneven size of the holes formed in the casing.Finally, the fracturing pressure of some strata exceeds the fracturing pressure of the formation. Therefore, the perforating industry began to pursue perforating hole consistency.
The segregation problem of tungsten, copper and other metal powders during mixing and spinning is solved through a cone-curve charge structure for Consistent Hole DP Shaped Charge. Finally, the distribution of effective jet structure modes is formed to overcome the adverse effects of different holsting clearance sizes on jet velocity.
