Monitoring dielectric fill in a cased pipeline

摘要

An inspection system employs a cased pipeline structure, a pulse generator system, a data acquisition system, and a processing system. The cased pipeline structure comprises a casing pipe structure, a carrier pipe structure arranged within the casing pipe structure to define an annular space, and fill material arranged within the annular space. The pulse generator system is configured to apply an electromagnetic signal to the cased pipeline structure. The data acquisition system is configured to detect electromagnetic signals propagating along the cased pipeline structure. The processing system analyzes electromagnetic signals detected by the data acquisition system for signal characteristics indicative of an anomaly in the cased pipeline structure.

1. An inspection system comprising:
a cased pipeline structure comprising
a casing pipe structure,a carrier pipe structure arranged within the casing pipe structure to define an annular space, andfill material arranged within the annular space; a pulse generator system configured to apply an applied electromagnetic signal to the cased pipeline structure such that electromagnetic characteristics of the fill material alter the electromagnetic signal as the electromagnetic signal propagates along the cased pipeline structure; a data acquisition system configured to detect detected electromagnetic signals propagating along the cased pipeline structure; and a processing system for analyzing detected electromagnetic signals detected by the data acquisition system for signal characteristics associated with the electromagnetic characteristics of the fill material that are indicative of an anomaly in the fill material arranged within the annular space of the cased pipeline structure; wherein the pulse generator system applies the electromagnetic signal, the data acquisition system detects the detected electromagnetic signals, and the processing system analyzes the detected electromagnetic signals in real time while the fill material is being arranged between the casing pipe structure and the carrier pipe structure.
