钛铁矿高密度水泥是用95℃水泥为基料,钛铁矿粉为填料的水泥产品。水泥干灰密度≥4×10~3kg/m~3,经四川石油管理局川西北矿区8口井的固井实践表明:高密度水泥与缓凝剂、减水剂配伍;采用单车配,单车抽注。达到水灰比低,水泥浆密度大,流动度好,保证了高压井的正常施工和良好的固井质量。 Ilmenite high-density cement is 95 ℃ cement as the base material, ilmenite powder for the cement products. Cement dry ash density ≥ 4 × 10 ~ 3kg / m ~ 3, cementing practice of 8 wells in Sichuan Northwest Sichuan Mining Area shows that: high density cement and retarder, water reducer compatibility; the use of bicycles, bicycles Draw. The water-cement ratio is low, the grout density is high, the fluidity is good, which ensures the normal construction of high-pressure well and good cementing quality.
