Abstract
A well pipe perforating gun (10) is improved by the utilization of a pulverable support structure (14) to hold the explosive shaped charges (18a, 18b, etc.) and the fireset (20). When the gun (10) is fired, the support structure (14) disintegrates substantially into fragments too small to obstruct the flow of oil or natural gas from a surrounding earth formation into or through the well pipe (12) within which the gun is disposed. Optionally, the support structure (14) is assembled from a number of segments (14a, 14b, etc.) linked together in sequential fashion.
