摘要

摘要:
南海深水油气资源丰富，但低温环境显著延缓油井水泥早期强度发展，制约固井安全与效率。为解决深水低温固井水泥早强不足问题，实现绿色低碳材料应用，本研究将稻壳灰（RHA）作为绿色辅助胶凝材料引入 G 级油井水泥，在 10 ℃低温条件下，系统研究 4 种粒径（11.4～56.9 μm）与 3 种掺量（5%，10%，15%）的 RHA 对油井水泥早期水化特性、抗压强度、放热规律及微观结构的影响。通过抗压强度测试、等温量热测试、热重分析（TG）及扫描电镜-能谱分析（SEM-EDS），揭示 RHA 粒径与掺量协同调控水泥水化的作用机制。结果表明：RHA 掺量与粒径共同控制水化进程、微观结构演化及水化产物生成；随 RHA 掺量增加，水泥石强度先升后降，1 d 强度在 5% 掺量时最优，3，7 d 强度在 10% 掺量时最高；随粒径细化，1，3 d 强度持续升高，7 d 强度呈先升后降趋势，T1RHA 整体表现最优。低掺量 RHA 依靠火山灰反应、成核位点效应与空间填充效应提升强度；高掺量则因稀释效应与颗粒团聚导致性能下降；粒径越细火山灰活性越强、放热越显著，但过细颗粒会因早期快速形成 C-S-H 凝胶包裹水泥颗粒，抑制后期水化。研究明确了低温下 RHA 优化油井水泥早期水化的调控机制，为深水低温固井绿色水泥体系设计提供理论依据与技术支撑。

Abstract:
The South China Sea is rich in deepwater oil and gas resources, but deepwater low-temperature environments significantly delay the early strength development of oil well cement, which restricts the safety, quality, and efficiency of cementing operations and increases engineering costs.
Objective and Methods
To solve the problem of insufficient early strength of oil well cement under low-temperature deepwater conditions and promote the application of green low-carbon building materials in petroleum engineering, rice husk ash (RHA), as an eco-friendly supplementary cementitious material, was incorporated into Class G oil well cement in this study. A systematic experimental investigation was conducted at a low temperature of 10℃ to reveal the effects of RHA particle size (four grades: 11.4-56.9 μm) and dosage (5%, 10%, 15%) on the early hydration characteristics, compressive strength development, hydration heat release behavior, hydration product evolution, and microstructure formation of oil well cement pastes. A series of characterization methods were adopted, including compressive strength test, isothermal calorimetry, thermogravimetric and derivative thermogravimetry (TG) analysis, and scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (SEM-EDS).
Results
The results showed that RHA dosage and particle size synergistically regulated cement hydration kinetics, microstructure evolution, and the generation of hydration products, thereby dominating the mechanical performance of hardened cement pastes. With the increase of RHA dosage, the compressive strength increased first and then decreased. The 1-day strength reached the maximum at 5% RHA dosage, while the 3-day and 7-day strengths reached their peaks at 10% RHA dosage. As RHA particles were refined, the 1-day and 3-day strengths increased continuously, whereas the 7-day strength rose first and then declined, with the T1RHA group exhibiting the optimal overall performance. Low-dosage RHA enhanced cement strength through three mechanisms: Pozzolanic reaction, nucleation site effect, and spatial filling effect. In contrast, high-dosage RHA caused performance degradation due to the dilution effect and particle agglomeration. Finer RHA possessed higher pozzolanic activity and more intense hydration heat release. Nevertheless, excessively fine RHA accelerated the early formation of C-S-H gels, wrapping unhydrated cement particles and hindering subsequent hydration. The TG results verified that RHA consumed calcium hydroxide (CH) via pozzolanic reaction to generate additional C-S-H gels, optimizing the composition and microstructure of hydration products. SEM-EDS observations showed that RHA refined the pore structure, converted amorphous C-S-H into fibrous and ribbon-like morphologies, and lowered the Ca/Si molar ratio, contributing to a denser microstructure.
Conclusion
This study clarifies the coordinated regulation mechanism of RHA particle size and dosage on the early hydration of oil well cement under low-temperature conditions, and provides a theoretical basis and technical support for the design and application of green and low-carbon cementing systems suitable for deepwater low-temperature environments.
