Abstract:
An electric submersible pump assembly with integral heat exchanger, high-speed self-aligning bearings, and dual bearing thrust chamber is described. The described pump assembly, modules, and components may be used for operating an electric submersible pump at high speeds as well as over a wide range of speeds and flowrates without replacing downhole equipment. The described pump assembly may be shorter than comparable pump assemblies and may be assembled offsite, thereby leading to faster and easier installation with less down time. By operating over a wide range of speeds, the disclosed pump assembly allows the operator to reduce overall inventory, reduce down time for the well, and avoid other complications associated with replacing a pump assembly or other downhole components.

Claim (Index 1):
A thrust chamber arranged to transfer thrust from a shaft to a thrust bearing, the thrust chamber comprising:\n a shaft, wherein the shaft is operably connected to at least one impeller wherein the impeller generates downward thrust when in operation; a thrust chamber outer housing; a first thrust runner, wherein the first thrust runner is coupled to the shaft and comprises an upward facing thrust transferring surface and a downward facing thrust transfer surface; a first thrust bearing assembly coupled to the outer housing; wherein the first thrust bearing assembly comprises an upward facing thrust receiving surface and wherein the first thrust runner is configured to transfer downward thrust from the shaft to the first thrust bearing assembly; an up-thrust bearing assembly coupled to the outer housing, wherein the up-thrust bearing assembly comprises a downward facing thrust receiving surface and wherein the first runner is configured to transfer upward thrust from the shaft to the up-thrust bearing assembly; a second thrust runner, wherein the second thrust runner is coupled to the shaft and comprises a downward facing thrust transfer surface; a second thrust bearing assembly coupled to the outer housing, wherein the second thrust bearing assembly comprises an upward facing thrust receiving surface and wherein the second thrust runner is configured to transfer downward thrust from the shaft to the second thrust bearing assembly; a first and a second damper, wherein the first damper is configured to absorb downward thrust from the first thrust runner and transfer the downward thrust to the first thrust bearing assembly and the second damper is configured to absorb downward thrust from the second thrust runner and transfer the downward thrust to the second thrust bearing assembly; and a thrust chamber heat exchanger, wherein the thrust chamber heat exchanger comprises a thrust chamber interior housing and thrust chamber lubricant return path, wherein the thrust chamber interior housing is disposed within the thrust chamber outer housing and defines a thrust chamber heat exchanger lubricant pathway therebetween, and wherein the thrust chamber lubricant return path is in fluid communication with the thrust chamber lubricant pathway and is disposed within the interior housing.
