Embodiment Construction

[0011] In one aspect, the present invention relates to apparatus and methods for providing a quick connect housing structurally and functionally incorporated into a time delay module. The present invention is susceptible to embodiments having different forms. For example, the quick connect housing may be adapted for use with other downhole tools, such as packers, tubing cutters, wellbore patches, and other well completion tools. The specific embodiments of the invention shown in the drawings and to be described in detail herein should be understood to be illustrative of the principles of the invention and not intended to be limiting to what is shown and described herein.

[0012] see first figure 1 , which shows a well configuration and / or hydrocarbon producing facility 30 located above target formations 32 , 34 separated by an interstitial zone 36 . However, the teachings of the present invention can be applied to any type of formation. The facility 30 may be an onshore or...

Abstract

Quick connect couplings for coil run tools facilitate assembly and disassembly when deploying these tools. This quick connect fitting utilizes an inner mandrel (160) with a locking sleeve system (162) and a locking collet (132). Such quick connect fittings do not require precise alignment between mating components.

Description

technical field [0001] The present invention relates to apparatus and methods for connecting downhole tools. Background technique [0002] One activity associated with the completion of oil and gas wells is the perforation of the well casing. In this procedure, perforations, such as channels or holes, are formed in the well casing to enable fluid communication between the wellbore and the hydrocarbon producing formation interspersed by the wellbore. These perforations are usually made with perforating guns that contain shaped charges. The gun is lowered into the wellbore on coiled tubing until it reaches the desired target depth; for example near a producing formation. [0003] One disadvantage of running tooling up and down flexible pipe is the need for proper alignment of the threads on the two mating components. This requires manual manipulation of these two components with the suspension in a vertical attitude. Due to the weight of the gun assembly and environmental ...
