| 摘要 |
A jet pump assembly 10 for use in a subterranean wellbore 82 to lift produced fluids 72 to the surface, comprising a fixed type jet pump assembly 10 including a retrievable insert assembly 30 for retrieving substantially all working components of the jet pump assembly 10 which may be subject to wear or size change, including retrieving the standing valve assembly in the production intake section 50, and having a power section 40 which is reversible such that the same components may be used for operating the jet pump assembly 10 in "normal" circulation or "reverse" circulation. Included is an embodiment of a jet pump assembly 10 providing at least one pressure sensor 90 and at least one temperature sensor 92 built into the through bore of the retrievable insert section 30 for monitoring fluid pressure and temperature in the through bore of the jet pump assembly 10 and thereby improving operational efficiency of the jet pump assembly 10.
