Adsorption of Calcium and Magnesium Ions and Thickening Effect
Bibliographic record
Abstract
Waste water rich in high-concentration Ca 2+ 、Mg 2+ in a block of Daqing Oilfield, the influence of Ca 2+ and Mg 2+ on polymer solution viscosity is considered. To use of sodium humate solution which compound by turf and NaOH complexed Ca 2+ and Mg 2+ , reduced the impact of Ca 2+ and Mg 2+ on the polymer solution viscosity, so reached oilfield reinjection water viscosity standards. Research show that polymer solution viscosity lossed seriously when Ca 2+ and Mg 2+ content in 0 ~ 200mg / L, viscosity loss rate reached maximum 63.2% and 70.7%, respectively. The adsorption ratio of Ca 2+ reached 77.50% when amount of sodium humate solution were 8mL. Similarly, the adsorption ratio of Mg 2+ reached 83.60% when amount of sodium humate solution were 6mL. This indicated that sodium humate have great adsorption to Ca 2+ and Mg 2+ . Indoor experimental results confirmed the feasibility of using sodium humate complexed Ca 2+ and Mg 2+ to prevent viscosity of polymer solution reduced, and provides a reference for the field test.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
