Oil-Gas-Water Three phase Gauge 1：Technical Features   Three-phase flow gauge is a worldwide challenge, and to date, no low-cost, high-reliability, high-performance three-phase flowmeter has been developed internationally. Existing measurement methods mostly utilize traditional instruments and separation devices, which are costly, bulky, low in reliability, and large in size. These limitations prevent their widespread adoption in oil fields, thereby hindering the progress of digitalization and intelligentization in the oil industry. With the support of major national special projects and after nearly 20 years of research, an original three-phase flow gauge instrument has been developed through the integration of eight sensors and probes   1.1 structural characteristics 1:inseparable Reduced volume, weight, and It reduces costs and is easy to install and transport. 2:No active parts It has improved the reliability of long-term operation and will not be bonded by crude oil 3:Non-radioactive The impact of radioactive sources on the environment has been eliminated, protecting the environment 4:No pressure difference No additional pressure difference is generated, which is conducive to reducing the production pressure difference 5:Full bore No blockage, with an inner diameter identical to that of the crude oil pipeline, ensuring a smooth pipeline and, consequently, a smooth instrument   1.2:Technical advantage A:high reliability: It works stably all year round and can survive the winter safely B:High safety: even in the event of a malfunction, unattended operation will not affect normal production C:Low cost: low lifecycle cost, affordable for low yield wells D:High precision: with errors within the scope of management measurement requirements E:Small size: suitable for wellhead installation, does not affect existing production processes F:Low power consumption: no heating device, power below 15W.   1.3:Originality A new set of thinking methods and innovative systems has been formed in terms of structure, measurement system, data processing, theoretical models, etc., which has overturned the traditional three-phase current measurement method A:Structure: Apart from the oil pipe, there are only various sensors and measurement circuits, with no other components B:Measurement system: Three phase current measurement is achieved through the fusion of eight sensors or probes, including electromagnetic sensors C:Data processing: Established a data clustering analysis algorithm that can simultaneously identify the oil, gas, and water flow rates of multiple wells D:Theoretical Model: Established a multiphase flow measurement theory based on fluid mechanics   1.4:Achieved performance and level: achieved small size, high reliability, low cost, easy to popularize and promote A:Volume, rectangular,1050×300×1070mm B:Reliability, from April 2021 to present, after four years of on-site application with hundreds of instruments, the long-term operational reliability is 98% C:Cost of use, suitable for single well, with lower cost than other instruments 1.5:Progressiveness of technical indicators Innovating in structure and measurement system, improving reliability, and reducing costs without compromising performance, relying on advanced measurement models and algorithms to ensure good accuracy.
