Product Description

Oilfield Downhole Tools Slickline Wireline Hydrostatic BailerI. Introduction

A 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. 

It is mainly composed of upper contact, spring, valve element, short piece I, barrel, piston, short piece II, connecting sleeve, jarring sleeve, short piece III, pipe shoe, cylindrical pin, shear pin, seal ring, steel ball, etc. See the concrete structure in the figure.

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.
