summary:

This article briefly introduces the application of Feishibote domestic caliber electromagnetic flowmeter in the expansion project of CNOOC Kenli 3-2 oilfield. It accurately measures the total flow in the separation riser and replaces the use of large-caliber electromagnetic flowmeters, overcoming the bottleneck problem of electromagnetic flowmeters in my country that currently meet the requirements of high pressure, corrosion resistance and large diameter.

Keywords: electromagnetic flowmeter; high pressure; caliber

In recent years, my country's scientific and technological progress has developed rapidly. In addition, electromagnetic flowmeters have gradually become key equipment in many industries, such as industrial production and technical testing. Electromagnetic flowmeters have good corrosion resistance and are reliable in use, and have strong development prospects. Oilfield irrigation measurement and verification also belongs to the scope of liquid detection. Therefore, the application of has achieved good application results, improved the accuracy and effectiveness of oilfield irrigation measurement and verification, provided a strong reference basis and reference for oilfield development and design, and effectively gave full play to the value of electromagnetic flowmeters.

The WPFB (Wellhead Protection Frame B) module of the Kenli 3-2 oilfield expansion project was successfully started at the offshore engineering Tanggu site, marking the full launch of the onshore construction work of the Kenli 3-2 oilfield expansion project.

The intelligent overall planning demonstration project carried out by the Tianjin Branch of the Kenli 3-2 Oilfield Expansion Project will, in the future, transmit relevant information such as the ambient temperature, working pressure, liquid level meter, total flow, working status, etc. of various machines on the service platform to the control terminal in real time. At the same time, it can accept remote control and remote adjustment from the remote operation center, and have a certain remote control calibration function.

In the Kenli 3-2 oilfield expansion project, because the imported instrument panels are relatively expensive and have a long delivery time, close communication was carried out in the early planning stage to select the Fischer & Porter high-pressure electromagnetic flowmeter (nominal diameter 1500LB, operating temperature 75°C) from Chengde City to replace imported products. Since its delivery and use in 2019, it has been in good operating condition and has safe and reliable characteristics.

Electromagnetic flowmeter characteristics

Electromagnetic flowmeter is an inductive instrument that detects the volume flow of dielectric media in pipes based on Faraday's Ampere's law. It can achieve high-standard stable and accurate measurement for extreme working conditions, such as slurry liquids such as mortar, ore pulp, paper pulp with high concentration or liquids with low resistivity; full digital signal processing, good anti-interference ability, accurate measurement, and accuracy of 0.2%; multi-layer structure design, working pressure can reach 2500LB; accurate measurement pipe is unobstructed, with low wind resistance, durable, and low straight pipe section requirements. Its products have been widely used in the fields of wastewater, paper pulp, mortar, coal slurry, etc. for accurate total flow.

In the measurement and verification of oil field water injection, the Fischer & Porter high-pressure electromagnetic flowmeter is used. Its application effect significantly enhances the measurement accuracy of water injection flow, and the measurement error is very small. In addition, because the electromagnetic flowmeter also has the remote water meter function of modulated signal, it can provide relevant service support for the intelligent production video monitoring system of oil field water injection station in use. The efficient operation of the high-pressure electromagnetic flowmeter ensures the normal mining activities of the oil field.
