Well tool assemblies with quick connectors and shock mitigating capabilities
First Claim
1. A method of interconnecting and securing a well tool in a well tool assembly, comprising:
- interconnecting and securing the well tool in the well tool assembly with a shock mitigating connection, the shock mitigating connection being made by inserting a first connector into a second connector without relative rotation between the first and second connectors, wherein an engagement device permits relative displacement between the first and second connectors in one longitudinal direction, but prevents relative displacement between the first and second connectors in an opposite longitudinal direction; and
then positioning the well tool assembly in a wellbore.

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.

16. A method of assembling a perforating assembly, the method comprising:
prior to installing the perforating assembly in a wellbore, pushing a first perforating device connector into a second perforating device connector without relative rotation between the first and second connectors, thereby;
a) preventing disconnection of the first connector from the second connector and b) making a connection in a detonation train, wherein an engagement device permits relative displacement between the first and second connectors in one longitudinal direction, but prevents relative displacement between the first and second connectors in an opposite longitudinal direction.- View Dependent Claims (17, 18, 19, 20, 21, 22)
