Evaluation of the Gel Profile Control Agent Polyacrylamide in Enhanced Oil Recovery
Bibliographic record
Abstract
Based on the system of anionic delayed cross-link polymer gel type deep profile control agent, experiments are conducted to evaluate the performance of long-term thermal stability, shearing resistance, and compatibility with natural debris of profile control agent and compatibility with ASP compound system. Besides, experiments are completed to simulate core displacement profile controlling and evaluate effect of oil displacement. Formula of anionic delayed cross-link polymer gel profile control agent with ideal long-term stability is confirmed. Profile control effect referred to core with diverse permeability and influence law of different injection time and injection rate on effect of oil displacement. Following conclusions are made according to the research. Long-term thermal stability, shearing resistance, and compatibility with natural debris of profile control agent and compatibility of ASP compound system of anionic delayed cross-link polymer gel profile control agent all have good performance, as well as core plugging effect and resistance to erosion. Displacing effect varies with the profile control agent injecting time, which shows, injection before polymer displacing proves the best, injection during polymer displacing the second, and injection after polymer displacing the worst. At the same time, the value of enhanced oil recovery increases with the injection rate of profile control agent increasing, however, when the rate comes to the point of 0.1 pv, the increasing extent begins to slow down.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
