Abstract

The invention provides a GIS (Geographic Information System)-based operational control method and system for a pipeline cleaner or a detector. The operational control method comprises the following steps: acquiring a circuit graph layer of a natural gas pipeline by using a GIS; acquiring natural gas flow data in real time by establishing a pipeline model and using an SCADA (Supervisory Control and Data Acquisition) system; calculating a theoretic flow value of natural gas in the natural gas pipeline; controlling and adjusting the actual control flow value to be equal to the calculated theoretic value according to the actual natural gas flow data value acquired in real time; further controlling the operational speed of the pipeline cleaner or detector. The method and the system realize real-time control of natural gas flow of each trace point gate station of the natural gas pipeline, ensure that the flow data can be reasonably scheduled by detection personnel and further effectively control the operational speed of the pipeline cleaner or detector.

Description

technical field [0001] The invention relates to the field of natural gas transportation, in particular to a method for controlling a pig in a natural gas pipeline. Background technique [0002] According to TSG D7003-2010 "Periodic inspection rules for pressure pipelines - long-distance (oil and gas) pipelines", it is required that new pipelines should be inspected for the first time including internal inspection within 3 years of commissioning, and then periodically inspected according to the operating conditions and status of the pipeline. Internal detection. Internal detection means that the detector runs with the medium in the pipeline and collects and records pipeline information in real time, so as to detect the deformation and internal corrosion of the pipeline body. Pigging must be carried out before detection. During the detection process, there are strict requirements on the operating speed of the detector and the stability of the medium flow state, and the speed ...
