Simulating CO2 and Viscosity Dissolver Assisted Steam Flooding Technology in Extra-Heavy Oil Reservoir by Using 3-D Physical Modelling
Bibliographic record
Abstract
The macroscopic fluid flow mechanism of enhanced oil recovery (EOR) by CO 2 and viscosity dissolver assisted steam flooding technology for horizontal well (HDCS) is studied using “the 3-D physical modeling system of a complicated driving system under the realreservoir condition (high temperature and high pressure conditions) for EOR”. The production performance, pressure field and saturation field are measured with a differential pressure unit and saturation measuring probes. The resistance increased, the pressure increased and the flow direction changed under the physical and chemical actions of adsorption and the retention of the tannin extract. The tannin extract changed the flow direction from the main stream to the remaining oil regions on either side and displaced the remaining oil. The steam flooding not only displaced the residual oil in the main stream but also displaced the oil on either side by enlarging the swept volume from the main stream to the side.

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.
