Trajectory optimization of ultra-short sidetrack horizontal wells in marginal reservoirs
Published 2025-04-01“…The simulation results show that the production increases with a longer horizontal section length, a greater entry distance, and larger angles between the well and mainstream flow line. The numerical results reveal that the optimal horizontal well length is 200 m, the optimal well orientation is 120°–150° to the main flow line, and the preferred range of entry distance is 50–70 m. …”

Optimization of grouting reinforcement performance of superfine sulfoaluminate cement composite system
Published 2025-06-01“…Both water-reducing agents can effectively improve the slurry fluidity and prolong the setting time; ② The synergistic effect of retarder and water reducer shows differences: the introduction of 0.2% β-CD in PCE-modified system can make the compressive strength increase by 6.90%−17.18%, but more than the critical dosage of excessive retarder leads to strength attenuation; while the FDN system is compounded by CA dosing, the strength shows a monotonous decreasing trend with the increase of dosage, and the dosage of 0.6% CA dosage causes the strength loss of about 13.78%; fixing the dosage of the two water-reducing agents, with the addition of the corresponding retarder from 0 to 0.6%, the setting time of the grouting material is gradually extended, and the flow degree shows a high and then low change; ③ Microstructure analysis reveals that the water-reducing agent optimizes the morphology of caliche AFt through the regulation of the environment, and the retarding agent promotes the filling of pores with gel by retarding hydration, and the synergistic effect of the two inhibits the transformation of AFt to monosulfide type to a certain extent. …”
