Description

technical field [0001] The invention relates to the technical field of electric submersible pump cables, in particular to a preparation method of an impact-resistant electric submersible pump polypropylene cable insulating material. Background technique [0002] The electric submersible pump cable is a special cable used for submersible electric pump units, mainly used for power supply of large displacement wells (greater than 150m3 / d), deep wells (1000-3000m), horizontal wells and inclined wells ; The lower end of the cable is connected to the leading cable, and the upper end is connected to the ground control cabinet. It has been working for a long time in a highly corrosive oil well environment such as high temperature, high pressure, and oil and gas. At present, the insulation layer of the electric submersible pump cable has the disadvantages of poor thermal deformation temperature and impact strength, which need to be solved urgently.
