Damage mechanism analysis of electric submersible pump stuck in an offshore oil well with low permeability reservoir
In response to the high failure rate of electric submersible pumps in a low-permeability offshore oil reservoir,in-depth research has found that the production of low-permeability electric submersible pump wells fluctuates greatly,the impeller of the electric submersible pump is severely worn,and some high water content oil wells have sand production and scaling,blocking fluid channels and other factors,which cause the electric submersible pump to jam and stop.Methods such as improving the structure of the electric submersible pump,reasonable production system,and anti scaling and anti sand measures are proposed,Effectively reduce the failure rate of stuck electric submersible pump wells.
