Abstract

The invention discloses an underground multiphase flow vortex shedding flowmeter. The vortex shedding flowmeter comprises a vortex shedding flowmeter pipeline (1), a temperature sensor, a first O-shaped ring set, a vortex shedding probe, a clamping sleeve type pipe nut, an installation body, a second O-shaped ring set, a pressure sensor and a third O-shaped ring set. The vortex shedding probe andthe installation body are fixed through the clamping sleeve type pipe nut. The flow meter is provided with the temperature sensor and the pressure sensor, so that measurement of water, polymers and gas can be realized, injection pressure control is completed through monitoring of the temperature sensor and the pressure sensor, so that measured fluid is guaranteed to be in a fluid state capable ofbeing detected by the vortex street probe and then multi-phase flow fluid flow measurement is achieved. While the detachability of the vortex street probe is realized, problems that when a traditionalvortex street flowmeter is used in an underground rechargeable intelligent water distributor, materials are wasted, the design efficiency is low, the vortex shedding probe cannot be replaced in the later period, installation and maintenance are improper, and the failure rate is high are solved.

Description

technical field [0001] The invention relates to a flow meter used in the field of layered water injection in oil fields. Background technique [0002] Layered water injection has been widely used in oilfield development. The measurement and adjustment process of layered water injection is the core link of the whole water injection process, and the flow test is an extremely important link in the whole measurement and adjustment process. The vortex flowmeter has the advantages of high precision, high temperature resistance, high pressure resistance, electromagnetic interference resistance, no power supply, wide dynamic range, convenient remote measurement and control, and suitable for various media. It has been widely used in the petroleum field. The downhole water injection environment is complex, and the injectant may have problems such as low conductivity, corrosiveness, and impurity. Flow measurement also involves liquid, gas, and multiphase fluids, which enhances the anti...
