Introudction of Hydraulic Circulating Valve

 

The Hydraulic Circulating Valve is a kind of the circulating valve applied for the drill stem testing operation. The hydraulic circulating valve serves as a bypass around the packer or as a circulating valve to circulate a well after testing. When run below a closed valve, the hydraulic circulating valve serves as a bypass around the packer and helps relieve pressure buildup below the closed valve when it is stung into a production packer.When run above a closed valve, the hydraulic circulating valve can be used as a circulating valve when the workstring is picked up.

 

Features and Benefits of the Hydraulic Circulating Valve

 

* The hydraulic circulating valve permits passage of wireline tools through its full-opening bore
* The hydraulic circulating valve r
equires no pipe rotation to operate

 

Operation of the Hydraulic Circulating Valve

 

Bypass ports close when weight is set down and reopen when weight is lifted. A hydraulic metering system
provides a 2 to 3-minute delay in closing after weight is applied. This delay allows either the RTTS packer
to be set or the test string to be stung into a permanent packer before the bypass ports close. The ports
reopen without a time delay.


During stimulation work, the latching piston adds a downward force on the circulating sleeve to help keep
the valve closed. Operation of the valve is the same whether it is used as a circulating valve or as a bypass.
No torque is required. Weight is applied to close the tool, and the workstring is picked up to reopen it.

﹡HSE﹡Safety instructions of the Hydraulic Circulating Valve:

 

1. When running each pressure test, you must increase pressure gradually. When the pressure is up to 20MPa, hold on for one minute, then every 10MPa keep it for one minute until the rating pressure;

2. During doing the pressure test, the tool should be placed in the test pit and cover the protecting board on the pressure test plug.

3.During the whole process, make sure the entire test operator keep away from plug and joint which may lapse.

4.Test area should set isolation, others except operator not allowed to enter test area.

       5.If there is anybody in the test area, it should set isolation, avoiding test production fly off the test area.
