Determine the Inflow Performance Relationship of Water Producing Gas Well Using Multiobjective Optimization Method

Journal of Applied Mathematics, 2014
During the development of water drive gas reservoirs, the phenomena of gas escaping from water and water separating out from gas will change the seepage characteristics of formation fluid. Therefore, the traditional gas-water two-phase inflow performance

Microscopic seepage simulation of gas and water in shale pores and slits based on VOF

Open Physics
The microscopic pore-fracture structure and wettability have a significant influence on the two-phase seepage of shale gas and water. Due to the limitation of experimental conditions, the seepage patterns of gas and water in shale pores and slits under ...

Gas-water two-phase apparent permeability for inorganic shale pores considering fractal structure and multiple mechanisms of fluid storage and migration

Meitan kexue jishu
The apparent permeability of gas-water two-phase flow in the inorganic shale pore system of shale is a critical parameter for evaluating shale gas production and the flowback rate of fracturing fluid, and its accurate characterization provides a ...

Two-phase flow meter for determining water and solids volumetric flow rate in vertical and inclined solids-in-water flows [PDF]

Multiphase flow can be defined as the simultaneous flow of a stream of two or more phases. Solids-in-water flow is a multiphase flows where solids and liquid are both present. Due to the density differences of the two phases, the results for such flow is

Mechanism of coal wettability on storage state of undersaturated CBM reservoirs

Youqicang pingjia yu kaifa, 2022
The wettability decides the fluid distribution in porous media, and the wet-phase fluid will primarily occupy the smaller pore. Based on this principle, the paradox between laboratory test of coal wettability and state of fluids distribution is analyzed.
