The downward movement of the sleeve is arrested when the circumferential groove of the sleeve is aligned with the lower circumferential groove B of the housing assembly , because the spring ring decompresses radially outward to engage the lower circumferential groove of the housing assembly.
The diverter device is now in the closed port position. Once in the closed port position, drilling fluid pressure is increased to a second predetermined level above the drop ball [] to force the drop ball through the yieldable ball seat Therefore, when drilling fluid pressure is increased above the drop ball to shift the diverter device into the closed port position, the trapped drilling fluid will resist the downward shifting of the sleeve With the set of housing flow holes unobstructed, circulation and, more significantly, critical cementing operations cannot be performed.
Therefore, the volume compensation device , once activated, accumulates enough of the trapped drilling fluid to permit the sleeve of the diverter device to be shifted axially downward. Once a sufficient volume of the resisting drilling fluid is removed, the hydraulic lock condition ends and the sleeve is moved to the closed port position.
As the drilling fluid pressure above the drop ball is increased, the trapped drilling fluid beneath the drop ball forces the annular piston upward against the restraint of the shear pins Once the force against the annular piston is sufficient to shear the shear pins , the volume compensation device is activated and the annular piston is released from the lower end of the inner sleeve Once the annular piston [] is released, the trapped drilling fluid forces the annular piston upwards.
As the annular piston moves upward, the drilling fluid fills the volume vacated by the rising piston. As the drilling fluid pressure above the drop ball forces the sleeve of the diverter device to move axially downward, the trapped drilling fluid reacts by forcing the annular piston further upward filling in the vacated space below the piston until enough drilling fluid has been displaced to shift the sleeve into the closed port position. Furthermore, as the annular piston [] moves axially upward, it sweeps any fluid that has collected in the compensation volume annulus outward into the borehole via a set of holes It is also intended that the compensation volume annulus above the annular piston may be filled with a preservative compound such as grease to prevent contamination of the compensation volume annulus as the surge pressure reduction tool is run downhole.
Once the sleeve [] of the diverter device is in the closed port position and the set of housing flow holes is blocked, drilling fluid pressure is increased above the drop ball to push the drop ball through the yieldable ball seat What is claimed is: 1.
