Isolation Valve adapted Training Tools to build a column of the desired length before going down the column to the bottom of the well to Well operation

摘要

An apparatus adapted for use in connection with Operations pozoen a well to build a Toolkit of any desired length column before going down the column of the tools.To perform these operations or the well Pit, a scrolling Tool adapted to be run through a Center of the device.The Apparatus comprises: a Valve placed initially in a first position and adapted to be moved from the first position to a second position when the desplazami ToolThat passes through the center of the valve; The Shifting Tool is adapted to be built above the valve in the well,When the valve is changed by moving the tool to the second position, and a Section that includes a set of Hydraulic Drive Security responds to the change of the Vu00e1lvula the first position to the second position on the tool Displacement, passing through the center of the valve, and is alsoAnother Step of the tool displacement through the center of the section to switch back to the Hydraulic valve of the second position to the first position when a pressureIn This section, the Hydraulic pressure exceeds a Predetermined Threshold Value of the Whole Disk SecurityThe column of downhole Tools is lowered when the valve is to change back to the first position.
