Intelligent tool for detecting perforations and interpretation of data online

摘要

The present application relates to a tool for detecting perforations in hydrocarbon pipelines based on the sensing system thereof. The function of said tool is to pass longitudinally through a pipeline of specific diameter, monitoring the thickness thereof and detecting any hole over the path followed and, in accordance with the data obtained, establishing the distance at which the holes are located, calculated from the starting point, the time at the instant of detection and also the circumferential position and size thereof, all the aforesaid as part of an online process implemented as the tool progresses through the target pipeline. At the end of the run, the information may be downloaded to a computer where it is available for use and for the corresponding decisions concerning integrity.

1. A tool for the detection of perforations and interpretation of data online, comprising a battery module, a positioning and main control module that performs the analysis, interpretation and filtering of the information online, and a magnetic sensing module that performs the acquisition of primary information from the pipes perforations or defects,
wherein the positioning and main control module is divided in two sections, a first section for the acquisition of positioning data and a second section for supporting the main controller; wherein the first section comprises at least three odometers constituted by a wheel that is in contact with an internal pipe wall during a whole trajectory, and wherein two magnets are imbedded in the wheel and located on opposite sides of the same face of the wheel.
