Improvement of single-core current measurement for field-collecting electromagnetic flowmeter

A few days ago, good news came from Hailar. The improved single-core current collector electromagnetic flowmeter of the eleventh-big team of test technology service branch successfully accepted the test of Well Bay 57-53.

Collective electromagnetic flowmeter has been praised by Party A for its application in Hailar Oilfield. The eleventh unit logging team uses mostly single-core cables in the injection profile logging, and the collector electromagnetic flow logging requires the use of three-core cables. Therefore, the team employee needs to replace the three-core cable for testing every time this item is tested. The workload also affects the efficiency of the well. In response to this situation, at the beginning of this year, the Daqing team's young talents Guo Daolian and Xu Jiamei set out to improve the equipment. They designed overvoltage protection circuits and electronic switches to add to the original circuit. This new and improved instrument realizes a single-core measurement of the collector electromagnetic flowmeter in injection profile logging, and at the same time increases the stability of the instrument. New and improved instruments will be widely used in the Hailar Oilfield.
