    摘要： A shaped charge comprising a case, a liner positioned within the case, and an explosive filled within the case. The liner is shaped with a subtended angle ranging from 100° to 120° about an apex, a radius, and an aspect ratio such that a jet formed with the explosive creates an entrance hole in a well casing. The jet creates a perforation tunnel in a hydrocarbon formation, wherein a diameter of the jet, a diameter of the entrance hole diameter, and a width and length of the perforation tunnel are substantially constant and unaffected with changes in design and environmental factors such as a thickness and composition of the well casing, position of the charge in the perforating gun, position of the perforating gun in the well casing, a water gap in the wellbore casing, and type of the hydrocarbon formation.

    摘要： A perforating gun system having gun sections coupled together with adapters. Each of the gun sections are adjustable to be offset relative to one another and each gun section is also decentralized with respect to the inside diameter of the wellbore casing. Each of the gun sections are movable in succession to an interval in the wellbore casing to create perforations such that the percentage of the casing openings is large for substantial fluid flow. The alignment and diameters of the gun sections are chosen to occupy the entire inner diameter of the casing.

    摘要： A loading tube is configured to receive one or more shaped charges to form a perforating gun. The loading tube includes a tubular body extending along a longitudinal axis; a cord passage formed into the tubular body; a retention cutoff formed into the tubular body and configured to receive a detonator cord; and a holding element extending into the retention cutoff and being integrally made with a wall of the tubular body, wherein the holding element is configured to hold the detonator cord into the retention cutoff. The cord passage is configured to receive the detonator cord from a bore of the tubular body and to direct the detonator cord outside the bore of the tubular body.

    摘要： A perforating gun includes first and second shaped charges. Each of the shaped charges includes a case, a liner, and an explosive. Each liner has a subtended angle about an apex of the liner. A first jet formed by the first shaped charge creates a first entrance hole in a first region of a well casing, and a second jet formed by the second shaped charge, creates a second entrance hole in a second region of the casing. The second region is below the first region in the casing. A ratio of a diameter of the first entrance hole to a diameter of the second entrance hole is 1 when the subtended angle is between 100° and 110°, the ratio is less than 1 when the subtended angle is between 90° and 100°, and the ratio is greater than 1 when the subtended angle is greater than 110°.
