Abstract

A transportable well completion tool is described. The transportable well completion tool comprises a housing with a charge module disposed within the housing. The charge module comprises explosive charges. An initiator module comprising a detonator is coupled to the housing, and a bulkhead member is disposed within the housing between the initiator module and the charge module. A containment cover is secured to the housing to cover the detonator. The transportable well completion tool can be transported with the containment cover in place, and the containment cover can be removed to connect the well completion tool to a tool string for downhole deployment.

Claims (20)

1. A well completion tool, comprising:

a tubular housing;

a charge module comprising at least one explosive charge within the housing;

an initiation module coupled to the housing and comprising a detonator;

a bulkhead module within the housing between the charge module and the initiation module; and

a containment cover secured to the housing and covering the detonator, wherein the containment cover has detection means for detecting discharge of the initiation module before removing the containment cover.

2. The well completion tool of claim 1 , wherein the containment cover is secured to the housing by a threaded connection having a number of threads selected based on a discharge capacity of the initiation module.

3. The well completion tool of claim 1 , wherein the containment cover covers the initiation module.

4. The well completion tool of claim 1 , wherein the containment cover has a curved end.

5. The well completion tool of claim 1 , wherein the detonator is disposed along a central axis of the well completion tool.

6. A well completion tool, comprising:

a tubular housing;

a charge module comprising at least one explosive charge within the housing;

an initiation module coupled to the housing and comprising a detonator;

a bulkhead module within the housing between the charge module and the initiation module; and

a containment cover secured to an end of the housing and covering the initiator, wherein the containment cover has detection means for detecting discharge of the detonator before removing the containment cover.

7. The well completion tool of claim 6 , wherein the containment cover is secured to the housing by a threaded connection having a number of threads selected based on a discharge capacity of the initiation module.

8. The well completion tool of claim 6 , wherein the containment cover covers the initiation module.

9. The well completion tool of claim 6 , wherein the containment cover has a curved end.

10. The well completion tool of claim 6 , wherein the detonator is disposed along a central axis of the well completion tool.
