Title:
EXPERIMENTAL DEVICE AND METHOD FOR SYSTEMWIDE MONITORING OF SOLIDS AND EVALUATING DECLOGGING EFFECTIVENESS IN PIPELINE
Document Type and Number:
WIPO Patent Application WO/2019/120261
Kind Code:
A1
Abstract:
An experimental device and method for comprehensive systemwide monitoring of solids and evaluating declogging effectiveness in a pipeline. The device comprises a complex multiphase flow circulation system, a solids detection system (11), a data acquisition and transmission system, a solids status evaluation system, and a declogging system. The complex multiphase flow circulation system provides a fluid passage for an entire solids system. The solids detection system (11) performs real-time systemwide monitoring on solids in a pipeline, transmits monitored data to the solids status evaluation system by the data acquisition and transmission system, and provides a real time migration status of solids in the pipeline. The declogging system is used to inject a clogging inhibitor into the pipeline according to an evaluation result provided by the solids status evaluation system. The invention is applicable to monitoring and evaluation experiments on declogging effectiveness of oil, gas, hydrate, and fluidized mineral wells, and oil and gas mineral conveying pipelines that contain solids or that generate solids.
