Technical Field

The utility model relates to a metering device, concretely relates to heterogeneous flow measurement skid-mounted.

Background

At present, the metering device for the petroleum wellhead has single function and cannot simultaneously measure the contents of oil, gas and water; because the function is single, oil, gas and water need to be separately measured, the occupied area of the equipment is large, and the volume is huge; the use and maintenance costs are high due to the complex construction.

Disclosure of Invention

The utility model aims to provide a: the multiphase flow measurement skid-mounted device is provided, the integrated online measurement of oil, gas and water multiphase flow is realized, the working efficiency is greatly improved, and the use cost is reduced.

The utility model discloses a solution is: the multiphase flow metering skid-mounted device comprises a stop valve, a basket filter, a micro differential pressure multiphase flowmeter, a one-way valve and a union joint, wherein the stop valve, the basket filter, the micro differential pressure multiphase flowmeter, the one-way valve and the union joint are connected in series to form the metering skid-mounted device; connecting the whole metering skid in parallel with the oil well production pipeline, wherein the stop valve is used for switching the parallel pipelines; the basket filter is arranged at the upstream and used for filtering impurities in the fluid; the micro-differential pressure multiphase flowmeter is used for measuring the content of oil, gas and water; the check valve is used for preventing backflow; the union joint is used for connecting the mobile calibration device and performing emergency production.

The utility model has the advantages that: the integration level is high, the installation is simple, and the use and maintenance cost is low; the integrated online measurement is adopted, and the oil, gas and water contents of the produced liquid oil of the oil well are accurately measured; the normal production of the production pipeline is not influenced by the adjustment of the switch of the stop valve; when the normal pipelines have problems, the parallel pipelines are started for production, and the reliability is good.
