Abstract

The invention provides a device and method for diagnosing faults and testing performance of a single-screw pump. The operation condition of the single-screw pump can be subjected to online monitoring, fault diagnosis and performance testing. Two work modes, namely, a normal production monitoring mode and a performance online testing mode are provided in the device. In the normal production monitoring mode, based on real-time monitoring on running parameters of the pump in the normal production process, the online monitoring of the operation condition of the pump is achieved; and online diagnosis of common faults of the pump can be completed by means of online detected data, and a maintaining strategy is made on the basis. In the pump performance testing mode, pump performance testing of an in-service single-screw pump / an out-of-service single-screw pump under a common operating condition / extreme operating condition can be achieved, the pump capacity efficiency, the shaft power, the lift, the overall efficiency and other performance parameters can be calculated under different operating conditions, and a performance curve is drawn and stored on the basis.

Description

technical field

[0001] The invention belongs to the technical field of oil field testing, and relates to the fault diagnosis and performance test of multi-phase mixed transport pumps used in oil and gas gathering and transportation systems, in particular to an online fault diagnosis and performance test device for single screw pumps, and single screw pump fault diagnosis and performance testing. performance testing method. Background technique

[0002] In crude oil gathering and transportation, using gas-liquid mixed pipeline to transport crude oil and natural gas separately can simplify the gathering and transportation process, shorten the design and construction time of the gathering and transportation project, reduce the investment of the gathering and transportation project, and improve Economic benefits of oil field development. In the development of oil fields in specific environments such as deserts and offshore, mixed pipelines have incomparable advantages over sing...
