Webb15 nov. 2024 · Most of the earth’s surface is covered by seas. Deep underwater reservoirs have abundant resources of oil and gas. In the development of offshore oil and gas reservoirs, oil and gas transportation is performed by a pipe system combining a deep-water pipeline and a riser. In the process of transportation, differences in phase … WebbThe word slug usually refers to the heavier, slower moving fluid, but can also be used to refer to the bubbles of the lighter fluid. This flow is characterised by the intermittent sequence of liquid slugs followed by longer gas bubbles flowing through a pipe.

Severe slug flow (i.e., terrain-dominated slug flow) was studied in a simulated offshore pipeline riser-pipe system. Severe slug flow is characterized by extremely long liquid slugs generated at the base of the vertical riser. This phenomenon occurs at low gas and liquid flow rates and for negative pipeline inclinations. Slugging in … phil redmond agent

Webb17 maj 2024 · Slugs formed by terrain slugging, hydrodynamic slugging or riser-based slugging are periodical in nature. Whether a slug is able to reach the outlet of the pipeline depends on the rate at which liquids are added to the slug at the front (i.e. in the direction of flow) and the rate at which liquids leave the slug at the back. WebbOne of the methods for calculating the effect of slug flow loads is the static method. Vertical, horizontal, and resultant forces F can be determined by the formulas: where. θ – bend angle (90 degrees, 45 degrees, etc.) ρ – fluid density. v – slug velocity at the moment then it hits the bend. A – internal pipe cross-section area.
