Study and Application of a New Complex Plug Removal System
Bibliographic record
Abstract
Aiming at solving small effective acid reaction range and causing second damage in the acidizing in low permeability reservoirs, a new kind of deep penetration and little damage complex plug removal system was developed through laboratory research, which consists of an organic acid, a phosphoric acid, an ammonium organic acid, an ammonium fluoride and a strong oxidizer. The properties were evaluated and the results indicate that it has advantages of proper dissolving capacity to rock with dissolving ratio of 38.9%, little corrosion to the pipeline of equipment with corrosion rate of 2.9 g/m2·h-1, low interfacial tension, anti-acid-sludge, and ability to stabilize ferric ion. The plugging in deep formations can be removed with low damage to rock skeleton, which the damage rate is less than 20%. It has been applied in 19 wells with success ratio of 100% and long term of validity, average validity is more than 200 days. The oil production and water injection have been increased obviously. Key words : Acidization; Second damage; Complex plug removal system; Deep penetration; Rock skeleton

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.
