Sinopec News Network reported on September 17, the technical staff of Henan Oilfield Engineering Institute implemented the concentric measurement and adjustment integrated technology construction in the Wei 412 water injection well of Weigang Oilfield, and achieved success
"The water temperature is 70 degrees Fahrenheit, and the well is washed with 40 cubic meters of hot water.
The integrated technology of concentric measurement and adjustment for water injection wells is a key technology of subdivision water injection independently developed by Henan Oilfield Engineering Institute.
In response to the requirement of multi-stage and multi-stage fine water injection in the well, the technicians of Henan Oilfield Engineering Institute carefully inspected each concentric measuring and adjusting water distributor, and tested and tested in the laboratory to ensure the reliability and stability of the well-entry instruments
Up to now, the concentric measurement and adjustment integration technology has been used in 32 wells each year, and the annual water injection has increased by 170,000 cubic meters
