초록 ▼

A depressurization tool is described for use downhole in depressurizing an isolated zone. A decompression chamber containing a compressible fluid volume is described. The opening of the chamber is sealed with a closure that is configured to open upon application of a pressure differential across the opening. When used downhole within an isolated and nonpermeable wellbore zone, excessive ambient pressure will cause the closure to open and allow the chamber to fill with fluid at increased pressure, depressurizing the wellbore zone. The tool is useful in wellbore completion systems that include sliding sleeves.

대표청구항 ▼

1. A method for dissipating hydraulic pressure within an isolated zone of a wellbore, the method comprising: deploying a tool string into the wellbore, the tool string comprising a sealing device disposed on the tool string and a decompression chamber disposed on the tool string below the sealing device, the decompression chamber having an upper end adapted for connection to the tool string, the chamber defining a hollow interior and having an opening for admitting fluid from an annulus defined between the wellbore and the tool string into the interior of the chamber, the opening being sealed by a closure configured to isolate the chamber from the annulus defined between the wellbore and the tool string, the closure being openable in response to a predetermined fluid pressure differential between the annulus and the decompression chamber;lowering the tool string within the wellbore to locate the decompression chamber within the bottom of the wellbore;actuating the sealing device to hydraulically seal the wellbore region below the sealing device from the wellbore region above the sealing device and thereby form an isolated zone below the sealing device;effecting a wellbore operation while the isolated zone remains hydraulically isolated, the wellbore operation comprising raising the hydraulic pressure within the isolated zone such that the predetermined fluid pressure differential between the annulus and the decompression chamber is exceeded and the closure opens; andcollecting wellbore fluid from the isolated zone within the decompression chamber, thereby reducing the hydraulic pressure within the isolated zone. 2. The method of claim 1, further comprising deploying the tool string on coiled tubing. 3. The method of claim 1, further comprising lining the wellbore with a casing string comprising a housing with a port defined therethrough and an associated sliding sleeve disposed within the housing; and positioning the tool string adjacent to the sliding sleeve in the casing string. 4. The method of claim 3, wherein reducing the hydraulic pressure allows the movement of the sleeve from a closed position in which the sleeve is positioned over the port to an open position in which fluid communication through the port can occur. 5. A method for actuating a sliding sleeve located in a bottom region of a well bore, the method comprising: positioning a casing string comprising a housing having at least one port and an inner sliding sleeve disposed within the housing, the sliding sleeve actuable to slide between a first position in which the sliding sleeve is disposed over the port to a second position in which the port is not covered by the sleeve;deploying a downhole assembly into the casing string, the downhole assembly comprising a decompression chamber, the decompression chamber having a hollow interior and having an opening for admitting fluid from an annulus defined between the wellbore and the tool string into the interior of the chamber, the opening being sealed by a closure configured to isolate the chamber from the annulus defined between the wellbore and the downhole assembly, the closure being openable in response to a predetermined fluid pressure differential between the annulus and the decompression chamber, and a sealing element positioned above the decompression chamber;setting the sealing element so as to provide a seal between the sleeve and the casing string;delivering fluid to the wellbore above the sealing element, thereby creating a pressure across the closure sufficient to open the closure;dissipating wellbore fluid pressure in an annulus below the sealing element by movement of annular fluid to the interior of the decompression chamber; andmaintaining the fluid delivery to the wellbore, thereby causing the sleeve to slide from the first position to the second position. 6. The method of claim 5, further comprising carrying out a well treatment operation once the sleeve is in the second position.
