| 摘 要： | 在对国内外各种酸液体系研究的基础上，制备了一种缓速酸处理液——多氢酸酸液体系。确定了产品的最佳合成条件：丙酮与三氯化磷摩尔比为1：1，聚合反应温度为60℃，聚合反应时间为6h，引发剂过硫酸铵加量为10％。在此条件下得到的产品溶蚀率最高，达45．88％。制备的多氢酸具有较好的缓速性能，在地层温度下可保持较高的溶蚀率，与酸化体系中各种添加剂配伍性良好，可用于各种储层的改造。 |

| Abstract: | A retarted acid treatment solution, multi synthetic condition was as follows： the molar ratio of -hydro acid fluid system, was prepared. The optimal acetone to phosphorus trichloride was 1： 1, the polymeri- zation temperature was 60℃, the polymerization time was 6 h, the addition amount of initiator ammonium persulfate was 10%. The dissolution rate of the product prepared at above condition was as high as 45.88%. The multi -hydro acid showed good retarting property, high dissolution rate at the stratum temperature, and good compatibility with the various additives in the acidification system. The product was available in a variety of reservoir reconstruction. |
