Analysis of injection pressure

IOP Conference Series: Earth and Environmental Science, 2021
Abstract In the daily production of water injection wells, oil pressure is a very important production parameter. According to the existing theory, oil pressure plus liquid column pressure is the injection pressure at the bottom of the well, but this theory is contradictory to some production phenomena.

A Numerical Investigation of the Effects of the Fuel Injection Pressure and Nozzle Hole Diameter on Natural Gas–Diesel Dual-Fuel Combustion Characteristics

Energies
Natural gas–diesel dual-fuel (NDDF) engines can reduce harmful emissions while maintaining diesel-like efficiency. However, under low-load conditions, they suffer from high methane (CH4) emissions, reduced combustion stability, and lower thermal ...
