Technical Field

The invention relates to the technical field of oil and gas well logging, and belongs to a device for measuring the maximum outer diameter of an irregular cylinder.

Background

Shaped charge perforators are perforating devices that create oil and gas wellbores and formation pathways, and are retrieved from a wellbore after downhole perforation, and therefore, need to control their outer diameter expansion. The shaped charges with multiple radial perforations axially arranged in the shaped perforator generally have different perforation directions of two adjacent shaped charges, the wall of the perforator is expanded due to explosive impact of the shaped charges during perforation, the maximum outward expansion directions of the two adjacent expanded perforator walls are different due to different perforation directions, the outward expansion of the whole body is often larger than that of each monomer due to the combined action of the expansion in different directions on the shaped perforator, and therefore, single outer diameter expansion data measured by a vernier caliper and the like cannot represent the maximum outward expansion diameter of the shaped perforator.

At present, no similar device for measuring the maximum outer diameter of the irregular cylinder exists. The invention utilizes a cylinder sleeve with a certain length and equal aperture to pass through the energy-gathering perforator and simultaneously considers a plurality of outward expansion protruding points, and the position of the cylinder wall is fixed by the regulator so as to obtain the maximum outer diameter within a certain length.
