Ultra-fine oil well cement 
 Model: DMFC-OW-600/700/800/900/1100/1200 
 Products 
 The ultra-fine oil well cement is a new ultra-fine cementing material for bottom-hole temperature of 15-70 ° C oil and gas well cementing engineering and workover projects. 
 Features 
 1, the consistency in the process of cementing operations, the cement slurry has remained at low consistency (≤ 30BC consistency) run. Slurry consistency from 40BC-100BC transition time is short, about 5min-15min, can guarantee the cementing quality. 
 2, excellent flow and permeability. Able to penetrate the fine cracks of the cement sheath, formation and casing joints, condensation in the formation temperature and pressure hardening and sealing off the leaking water and gas along the cracks, the bottom of the well workover effect. 
 Permeability resistance, good corrosion resistance, resistance to sulfate attack resistance superior to ordinary Portland cement.

 Note 
 , Regulating the performance of cement must be a special admixtures. 
 2, cementing prior to the thickening properties of the admixture test. 
 , Cementing first admixtures soluble in water at any time with stirring at any time. 
 4, the product must not be mixed with other varieties of cement, changing varieties of cement, shall store, transport and mixing system to clean up.
