Research on Acidizing Fluid Accentuation

This paper has studied the conventional, new and compound methods of acid zing fluid accentuation. The expression of density and concentration of confecting acidizing fluid was gained by experimental data fitting. The expression about density and volume of growth rate of calcium chloride or calcium bromide solution correlating with amount of calcium chloride or calcium bromide was formed. The new acidizing fluid accentuation product was developed, in which the density reached 1.93 gram per cubic centimeter, and it is well compatible with other adjuvant. Complex calculation method was got by studying compounded accentuation technology, which could make the density of acidizing fluid range from 1.1 to 1.9 gram per cubic centimeter according to different hydrochloric acid concentration requirements. The results of these studies could supply technical support and reserves for deep well or ultra deep well acid, and promote oil and gas exploration and development toward the deep well and ultra deep well.
