This study numerically investigates counter-current slug flow by considering the motion of a
Taylor bubble in annular conduits with downward-flowing liquids using the Volume-of-Fluid …

The exploration and extraction of hydrocarbons from subsurface reservoirs rely heavily on
effective wellbore drift flow management. This research delves into the economic and …

Hydrate aggregation and deposition on the pipe wall are the main causes of hydrate
plugging in pipelines. Microscopic forces between hydrate particles are an important …

CO 2 transportation via pipelines and injection wells serves as the interface between carbon
sources and storage sinks and thus plays a vital role in large-scale CCUS. CO 2 is generally …

The friction coefficient is an important factor that affects the accurate calculation of wellbore
annular pressure distribution and is of great significance for the safety of drilling operations …

深水钻完井过程中, 受海水及海底地质条件复杂影响, 井筒压力控制精度要求高, 控制难度大.
高精度, 高稳定性的深水井筒多相流动模拟器成为解决井筒压力精细化控制的关键 …

Two-phase pipe flow occurs frequently in oil & gas industry, nuclear power plants, and
CCUS. Reliable calculations of gas void fraction (or liquid holdup) play a central role in two …

Most of the drift velocity models that exist have limitations, as they were developed based on
experiments that hardly considered the conjunction of liquid properties and pipe geometry …

During ultra-deep oil and gas exploration and development, overflow can easily occur when
drilling in high-temperature (≤ 473.15 K) and high-pressure (≤ 150 MPa) reservoirs. The …

The adhesion force between methane hydrate particles and wall droplets is an important
reference for studying the behavior of hydrate particles accumulating or detaching from the …
