Abstract

The invention discloses a speed regulation pipe cleaner control algorithm verification device and an experiment method. The method comprises the steps that a speed regulation pipe cleaner is arranged in a ball serving device; opening a gas-liquid supply system, adjusting gas-liquid flow at the same time, and obtaining pressure fluctuation and gas-liquid flow characteristics, so that serious slug flow appears in a pipeline system; after periodic serious slug flow occurs in the pipeline system and the pressure of the ball serving device reaches a preset pressure value, a pipe cleaner is fed into the pipeline system; collecting pressure data and gas-liquid flow patterns of the pipeline system, and the speed and liquid outlet amount of a speed-regulating pipe cleaner; and the gas-liquid supply system is closed, and the speed regulation pipe cleaner is taken out of the ball collecting device. According to the invention, the speed-regulating pigging device control algorithm under the condition of serious slug flow can be verified, so that the pressure fluctuation and the liquid outlet amount are minimized while the pigging efficiency is ensured under the condition of serious slug flow.

Description

technical field [0001] The invention relates to the technical field of deepwater riser pigging, in particular to a speed regulating pig control algorithm verification device and an experimental method. Background technique [0002] With the increasing scarcity of onshore oil and gas resources and the increasing difficulty of exploitation, the development of marine oil and gas resources has become a development trend. Like land pipelines, in order to ensure the quality of pipeline transportation, it is necessary to regularly use pigs to carry out pigging and inspection operations (pig and inspection are collectively referred to as pigging in the following) to remove wax deposits and accumulations formed by long-term transportation media inside the pipeline. Liquid, hydrate and other impurities, or timely detection of pipeline damage, corresponding maintenance and repair operations are carried out to avoid the occurrence of serious accidents. [0003] However, unlike land pip...
