The hydrostatic bailer is a wireline service tool used to clear the debris which has settled on the top of the subsurface equipment, preventing the recovery of the equipment by regular wireline operations.
when the sand pump bailer cannot fish the downhole sundries effectively, which is connected with the bottom of the basic tool string.
The interior of the barrel of the hydrostatic bailer is an atmospheric-pressure sealed chamber. When the bailer is lowered in place, the jar will move downward for a short distance, cut off the shear pin and a pressure difference is formed inside and outside of the bailer. Under the function of pressure difference, the sundries in the well and others will enter into the barrel and the steel ball will fall off, and then passageway is closed to prevent the sand from flowing back.

1. The tool is connected with the bottom of the basic tool string for use.
2. Lower the tool in place and move it downward, cut off the shear pin to form a pressure difference, finish bailing, and pull out the tool string.
1. While using, clear the rock sand in time and clean the interior of barrel.
2. When the tool is not used temporarily, paint the top threads with sealing grease and keep it with thread protector, and paint barrel with lubricating oil for rust protection.
