Control Line Set ESP Packer With Anti-Preset Device

Abstract

An apparatus and method of this disclosure include a downhole tool containing an anti-preset device in communication with a setting chamber configured to actuate at least one tool set feature of the downhole tool such as a cone-and-slip arrangement. The anti-preset device includes a control line with a port to setting chamber and a first rupture disk that prevents a control line fluid from passing through the port to the setting chamber until a first predetermined fluid pressure is achieved in the control line, the first predetermined fluid pressure being a burst pressure of the first rupture disk and achieved when the downhole tool is a desired depth with a wellbore.

1 . A downhole tool comprising:
 a setting chamber configured to actuate at least one tool set feature of the downhole tool;   a control line including a port configured for fluid communication with the setting chamber;   the control line further including a first rupture disk configured to prevent a control line fluid from passing through the port to the setting chamber until a first predetermined fluid pressure is achieved in the control line, the first predetermined fluid pressure being a burst pressure of the first rupture disk.   
     
     
         2 . The downhole tool of  claim 1 , wherein the downhole tool is a multi-string packer. 
     
     
         3 . The downhole tool of  claim 1 , wherein the burst pressure of the first rupture disk is in a range of 500 psi to 10,000 psi. 
     
     
         4 . The downhole tool of  claim 1 , wherein the burst pressure of the first rupture disk is in a range of 2,000 psi to 5,000 psi. 
     
     
         5 . The downhole tool of  claim 4 , the burst pressure of the first rupture disk being in a range of 3,000 psi to 4,000 psi. 
     
     
         6 . The downhole tool of  claim 5 , the burst pressure of the first rupture disk being in a range of 3,200 psi to 3,600 psi. 
     
     
         7 . The downhole tool of  claim 1 , wherein the control line fluid is hydraulic fluid. 
     
     
         8 . The downhole tool of  claim 1 , further comprising the control line including a second rupture disk configured to prevent the control line fluid from passing through the port to the setting chamber until a second predetermined fluid pressure is achieved in the control line, the second predetermined fluid pressure being a burst pressure of the second rupture disk. 
     
     
         9 . The downhole tool of  claim 8 , the first and second rupture disks having a same burst pressure. 
     
     
         10 . The downhole tool of  claim 8 , the first and second rupture disks having a different burst pressure. 
     
     
         11 . A method of actuating a downhole tool within a wellbore, the method comprising:
 connecting a control line of the downhole tool to a pump located at surface; the control line including a port configured for fluid communication with a setting chamber of the downhole tool, the setting chamber configured to actuate at least one tool set feature of the downhole tool;   running the downhole tool to a desired depth within the wellbore;   filling the control line with a control line fluid;   pressurizing, by way of the pump, the control line fluid to a first predetermined fluid pressure;   preventing the control line fluid from passing through the port to the setting chamber until the first predetermined fluid pressure is achieved in the control line, the preventing being done by way of a first rupture disk having a predetermined burst pressure equal to the first predetermined fluid pressure; and after the first rupture disk bursts, the setting chamber moving in response to the control line fluid and actuating the at least one tool set feature.   
     
     
         12 . The method of  claim 11 , wherein the downhole tool is a multi-string packer. 
     
     
         13 . The method of  claim 11 , wherein the burst pressure of the first rupture disk is in a range of 500 psi to 10,000 psi. 
     
     
         14 . The method of  claim 11 , wherein the burst pressure of the first rupture disk is in a range of 2,000 psi to 5,000 psi. 
     
     
         15 . The method of  claim 11 , the burst pressure of the first rupture disk being in a range of 3,000 psi to 4,000 psi. 
     
     
         16 . The method of  claim 15 , the burst pressure of the first rupture disk being in a range of 3,200 psi to 3,600 psi. 
     
     
         17 . The method of  claim 11 , wherein the control line fluid is hydraulic fluid. 
     
     
         18 . The method of  claim 11 , wherein the downhole tool further comprises:
 the control line including a second rupture disk configured to prevent the control line fluid from passing through the port to the setting chamber until a second predetermined fluid pressure is achieved in the control line, the second predetermined fluid pressure being a burst pressure of the second rupture disk.   
     
     
         19 . The method of  claim 18 , wherein the first and second rupture disks having a same burst pressure. 
     
     
         20 . The method of  claim 18 , wherein the first and second rupture disks having a different burst pressure.
