Theory and Applications of Numerical Simulation of Permeation Fluid Mechanics of the Polymer-Black Oil
Bibliographic record
Abstract
Theory and application of numerical simulation of permeation fluid mechanics is discussed about the polymer--black oil (water, oil and gas) in this paper. In view of petroleum geology, geochemistry, computational mechanics of flow and computer technology, the mechanics model of three-phase flow (water, oil and gas) of the polymer is presented firstly, then a numerical algorithm consisting of a full implicit program, and an implicit computation for the pressure and an explicit computation for the concentration is given by structuring an upstream sequence and an iterative algorithm of implicit fined upwind fractional step finite difference to solve the pressure equation, the concentration equation and the saturation of chemical substance components. A type of software applicable in major industries has been made in consideration of ten-meters steps, hundreds of thousands nodes and tens of years and high accuracy and the application has been carried out successfully in analysis and simulation of major oil-fields extraction such as Daqing Oilfield, Shengli Oilfield and Dagang Oilfield and others, which gives rise to outstanding economic and social benefits. A precise analysis is given for a simplified model and an idea is presented to solve this international famous problem.

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.
