Multi-Cup Isoflux Gas Anchor Numerical Simulation of Oil-Water Separating

Article Preview

Abstract:

Gas anchor is also known as downhole oil and gas separator. It plays a role of separating the gas and oil before the fluid flows into the pump, thus to eliminate the influence of gas and improve pump efficiency. It can also extend the lifetime of the equipment and increase the oil well output. On the analysis of factors affecting the efficiency of gas anchor, I built 3D models in Gambit on the basis of the blueprint of multi-cup isoflux gas anchor. I used Fluent to calculate the multi-cup isoflux gas anchor separation of oil and gas with laminar flow model. Then I got the distribution of speed and pressure in the multi-cup isoflux gas anchor and derived the formula of local resistance ratio. Learned that on the application of the multi-cup isoflux gas anchor the pumping wells pump efficiency enhances on an average of more than 25%.
