A New Gas Injection System for Ultra-Thick Metamorphic Rock Buried Hill Reservoirs
Bibliographic record
Abstract
This article proposes a new gas injection system that is a kind of tridimensional gas injection mode applied in the middle-lower part of the reservoir during the process of gas injecting on the reservoir top, which is suitable for the tridimensional reservoir development[1-2]. This system can express the gravity-stable drive effect on the crestal gas injection as well as the effective using of waterflooded wells to form continual micro gas/water slug drive naturally, supply the producing energy timely, diminish the water sealing of waterflooded reservoir matrix, enhance the gas dialysis on fine crack and microscopic sweep efficiency and control the water content, thus improve the production rate and enhance the recovery. Tridimensional gas injection system has been verified by physical simulation and numerical simulation. Pilot testing on Xinggu 7 buried hill reservoir has acquired an actual effect to increase the oil production, boost the pressure and decrease the water cut. Key words: Tridimensional; Gas injection system; Ultra-thick reservoir; Buried hill; Gravity-stable drive; Waterflooded well

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.
