研究了河南和江西产海泡石的造浆率、酸溶性和悬浮体的流变性与稳定性,发现S-6号样品造浆率达50—60m~3/t,大大超过API标准;海泡石悬浮体的流变性服从Brinkman粘度公式,S-5样品的Einstein形状系数K=57;配制海泡石泥浆时可使用常规的降失水剂,降失水剂的册量在复配时可大大降低;海泡石样品的酸溶量达26.6％。在地热、海洋、超深井钻探及配制完井液等方面,海泡石有良好的应用前景。
The production rate, acid-solubility and the rheological property and stability of sepiolite from Henan and Jiangxi were studied. It was found that the slurrying rate of S-6 was 50-60m ~ 3 / t, much higher than the API standard. Sea The rheological properties of the foam stone suspension obey the Brinkman viscosity formula, and the Einstein shape coefficient K of the S-5 sample is 57; when the sepiolite slurry is prepared, the conventional fluid loss additive can be used. When the volume of the fluid loss additive compound Can be greatly reduced; acid content of sepiolite samples up to 26.6%. Sepiolite has good application prospects in geothermal, oceanic, ultra-deep drilling and well preparation.
