The Study on Sand Consolidation Agent Formula System of H Block
Bibliographic record
Abstract
The cemented type between particles in H block is mainly pore-contact, which belongs to medium porosity, medium or low permeability reservoir, and the quality of oil belongs to thin oil. Since H block was put into production in 1988, the changes of formation pressure, erosion of water on formation and other reasons had caused sand production problem in H block. In order to reduce the disadvantages of sand production in oil and gas well and according to the analysis of sand production reasons in H block, this paper puts forward a kind of sand consolidating system that is suitable for H block. By indoor experiment, this paper optimizes the curing agent amount, thinner agent content, softener dosage, coupling agent and glass fiber content, also sand consolidating agent content. In addition, considering the two indicators of compressive strength and water permeability, this paper optimizes the composition of this sand consolidating agent, namely using epoxy resin as main agent; curing agent amount is 6.4%; softener dosage is 15%; thinner content is 22%; content of coupling agent is 2%; fiber dosage is 10%; appropriate injecting amount of sand consolidating agent is 1 pv.

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.
