Introudction of RD Safety Circulating Valve

 

The rupture disk / RD safety circulating valve is a sort of circulating valve, used in drill stem testing operation to serve as both a safety valve and circulating valve.

When the annulus pressure reaches a predetermined value, the RD circulating safety valve functions as a safety valve.  At that pressure, the RD safety circulating valve isolates the workstring below the tool and establishes communication between the annulus and the workstring above the tool.

When the ball valve section is removed and attach a lower adapter called RD Circulating Valve, this RD safety circulating valve is converted into a circulating valve .

The RD circulating safety valve can not be open when closed in downhole operation.

 

Feature of  RD Safety Circulating Valve Structure 

 

The RD circulating safety valve consisits three major sections:

1. The power section is compsed with a power mandrel case and rupture disk which is available for a wide range of pressure applications. When rupture disk bursts at a predetermined pressure, it allows annulus pressure to be applied to a differential area on the power mandrel. The power mandrel moves down, first pushing the ball valve closed, and then opening a set of circulating ports.

2. The circulating section is composed with a set of ports. When the rupture disk bursts, the power mandrel moves down, the ports will be exposed, which allows communication between the annulus and workstring.

3. The safety valve is composed of a ball valve, operating pins, and collet fingers. As the power mandrel moves down, the operating arms close the ball valve. The collet fingers expand, allowing the power mandrel to continue traveling down to open the circulating ports

 

How to operate the RD Circulating safety valve

 

During the drill stem testing operaion, before the RD circulating safety valve is run in the hole,  the operating pressure must be calculated for selecting the proper rupture disk pressure rating. To confirm the proper rubture disk pressure rating, it requires information including mud weight, bottom hole temperature, testing depth and maximum annulus pressure. When the rupture disk circulating valve is run with an annulus pressure-operated valve, the safety valve operating pressure should be kept 1,000 PSI above the operating pressure of the tester valve.
