一种油井复合解堵剂及其制备方法
摘要：
一种油井复合解堵剂及其制备方法，由如下质量百分比的组分组成：酸液1.0～10.0％、渗透剂1.0～5.0％、粘土稳定剂1.0～5.0％、铁离子稳定剂1.0～5.0％、助排剂1.0～5.0％、缓蚀剂1.0～5.0％、杀菌剂1.0～5.0％和余量水。将所述各组分按所述质量百分比混合搅拌均匀，即可制备得到。本发明所述的复合解堵剂具有显著的解堵效果，实现了无机物解堵和有机高分子聚合物解堵的一次进行，节省施工次数，且抗腐蚀效果好、有效期长且克服了常用解堵剂不安全的隐患，在解除油井堵塞和欠注等方面具有广阔的应用前景。
摘要（英）：

The invention provides a composite blocking remover for an oil well and a preparation method thereof. The composite blocking remover comprises, by mass, 1.0 to 10.0% of an acid solution, 1.0 to 5.0% of an osmotic agent, 1.0 to 5.0% of a clay stabilizing agent, 1.0 to 5.0% of an iron ion stabilizing agent, 1.0 to 5.0% of a cleanup additive, 1.0 to 5.0% of a corrosion inhibitor and 1.0 to 5.0% of a bactericide, with the balance being water. The above-mentioned components are uniformly mixed under stirring in proportion so as to prepare the composite blocking remover. The composite blocking remover prepared in the invention has substantial blocking removing effect, realizes simultaneous construction blocking removal and organic polymer blocking removal, reduces construction frequencies, exerts good corrosion resistance, is long in shelf life, overcomes the hidden trouble of unsafety of conventional blocking removers and has wide application prospects in the aspects of blocking removal, short shot and the like of the oil well.
