Abstract

In one instance, a dual-booster power charge is disclosed for use in a downhole setting tool, wherein the dual-booster power charge has at least a first and a second booster charge disposed within a sleeve and embedded in a main power charge. Each booster charge has one end face that is exposed at the end of the dual-booster power charge. Each booster charge may have a first dimension near the end face that is smaller than a second dimension near the end of the booster charge that is not exposed. In some instances, the booster charges have a charge retention portion and a primary body portion, and a cross sectional diameter of the charge retention portion is larger than a cross sectional dimension of the primary body portion. Other dual-booster power charges and booster charges are disclosed.

Dependent claims

A dual-booster power charge for energizing a downhole tool comprising:

a sleeve having a first end and second end and an interior cavity;
a main power charge disposed within the interior cavity of the sleeve;
a first booster charge comprising:
a first booster charge body having a first end and a second end,
wherein a first lateral dimension of the first end of the first booster charge is less than a second lateral dimension of the second end of the first booster charge,
wherein the first booster charge has an outward end face at the first end,
wherein the first booster charge is disposed within the main power charge proximate the first end of the sleeve such that the outward end face of the first booster charge is exposed;
and
a second booster charge comprising:
a second booster charge body having a first end and a second end,
wherein a first lateral dimension of the first end of the second booster charge is larger than a second lateral dimension of the second end of the first booster charge,
wherein the second booster charge has an outward end face at the second end, and
wherein the second booster charge is disposed within the main power charge proximate the second end of the sleeve such that the outward end face of the second booster charge is exposed.

A power charge comprising:

a sleeve having a first end and a second end and an interior cavity;
a main power charge disposed within the interior cavity of the sleeve;
a first booster charge having a first outward end face and wherein the first booster charge is disposed within the main power charge in the interior cavity of the sleeve proximate the first end of the sleeve and with the first outward end face exposed;
wherein the first booster charge has a first end and a second end, the first end being proximate to the first outward end face of the first booster charge;
wherein a diameter of the first booster charge proximate to the first end of the first booster charge is smaller than a diameter of the first booster charge proximate to the second end of the first booster charge;
a second booster charge having a second outward end face and wherein the second booster charge is disposed within the main power charge in the interior cavity of the sleeve proximate the second end of the sleeve and with the second outward end face exposed;
wherein the second booster charge has a first end and a second end, the second end being proximate to the second outward end face of the second booster charge;
and
wherein a diameter of the second booster charge proximate to the second end of the second booster charge is smaller than a diameter of the second booster charge proximate to the first end of the second booster charge.
