| 中文摘要: |
| 本文针对吐哈油田红台区块地层承压能力低、封固段长等固井难题，以紧密堆积理论为基础，依靠活性材料和固相颗粒级配等手段，设计出1.35、1.40 g/cm3的低密度水泥浆体系，并在该区块得到应用，解决了红台区块固井难题，使该区块的固井一次合格率达100%，提高了红台区块的固井质量。 |
| 英文摘要: |
| Aiming at the well cementing problems of low pressure and long sealing section of Tuha Oil Field, based on the theory of close packing, and by means of active material and solid particle size distribution, 1.35,1.40 g/cm3 of low density cement slurry is designed, which is applied in the block and solves the Hongtai oilfield cementing problem, makes the primary qualification rate of cementing reach 100%, and improve the cementing quality. |
