The Bench Test and Field Test of Rotary Steering Motor (RSM) System
Bibliographic record
Abstract
Rotary steering system may improve drilling speed, reduce downhole accidents and decrease drilling cost greatly when it is used to drill extended reach well and multilateral horizontal well. The feature and components of Rotary Steerable Motor (RSM)system are first briefly introduced in this paper : it consists of rotary steerable head, mud motor and flex sub and works in Push the Bit mode, steering or non-steering condition and each blade are controlled by using independent electromagnetic valves, mud motor provides power for bit and the hydraulic system by driving shaft; then the pre-test procedures, test set-up and procedures of bench test are described in detail: including blade sequence test, blade firing delay time test and acceptance test of RSM system, finally the note and analysis of the field tests of RSM system in ShengLi Oil Field are enumerated. The bench tests and field tests show that control method of this system is simply, reliable and easily realizable, with improvements this system will be used in practical application soon. Key words :Rotary Steering Motor (RSM) System; Mud motor; Bench test; Field test; Steering blade

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.
