Well tool assemblies with quick connectors and shock mitigating capabilities

Abstract

A method can include interconnecting a well tool in a well tool assembly with a shock mitigating connection, the interconnecting being performed without threading, and positioning the well tool assembly in a wellbore. A well perforating assembly can include at least two perforating devices, a detonation train extending through the perforating devices, and a shock absorber positioned between the perforating devices. A method of assembling a perforating assembly can include, prior to installing the perforating assembly in a wellbore, pushing one perforating device connector into another perforating device connector without threading the connectors together, thereby: a) preventing disconnection of the connectors and b) making a connection in a detonation train. A well system can include a perforating assembly including multiple perforating guns and multiple shock absorbers. Each shock absorber may be interconnected between at least two of the perforating guns.

         3 . A method, comprising:
 interconnecting a well tool in a well tool assembly with a shock mitigating connection which includes a sleeve having relatively coarse pitch profiles on one side, and the sleeve having relatively fine pitch profiles on an opposite side, the interconnecting being performed without threading; and   positioning the well tool assembly in a wellbore.

         5 . A method, comprising:
 interconnecting a well tool in a well tool assembly with a shock mitigating connection by pushing one connector into another connector without threading the connectors together, and engaging an engagement device that permits relative displacement between the connectors in one longitudinal direction, but prevents relative displacement between the connectors in an opposite longitudinal direction, thereby preventing disconnection of the connectors; and   positioning the well tool assembly in a wellbore.

         12 . A well perforating assembly, comprising:
 at least two perforating devices;   a connection between the perforating devices;   an engagement device that permits longitudinal compression of the connection, but prevents elongation of the connection;   a detonation train extending through the perforating devices; and   a shock absorber positioned between the perforating devices.   
     
     
         13 . The assembly of  claim 12 , wherein the connection comprises connectors attached to the respective perforating devices, and wherein the engagement device permits relative displacement between the connectors in one longitudinal direction, but prevents relative displacement between the connectors in an opposite longitudinal direction. 
     
     
         14 . The assembly of  claim 13 , wherein the connectors are connected to each other without threading together the connectors. 
     
     
         15 . The assembly of  claim 13 , wherein the detonation train extends through the connectors. 
     
     
         16 . A method of assembling a perforating assembly, the method comprising:
 prior to installing the perforating assembly in a wellbore, pushing one perforating device connector into another perforating device connector without threading the connectors together, thereby: a) preventing disconnection of the connectors and b) making a connection in a detonation train.   
     
     
         17 . The method of  claim 16 , further comprising positioning a shock absorber between the connectors.
