摘要： A method for installing a submersible pump assembly that allows deployment in a live well under pressure. In some of the embodiments, a pressure barrier is installed in the well lower than a length of the submersible pump assembly. The submersible pump assembly is lowered on a line into the chamber, then a lubricator at the surface seals around the line by allowing the pressure barrier to be released and the submersible pump assembly to be lowered into the well to a desired depth. Preferably, there is a lower pressure barrier in the well. The upper pressure barrier may be a packer that may be collapsed and retrieved alongside the submersible pump assembly. The pressure barrier also may be a packer that is temporarily set in the well, then engaged by the submersible pump assembly, with the pump assembly and packer then being lowered as a unit to a further depth in the well.
