一种储层酸化增注施工用螯合剂及其制备方法和应用
摘要：
本发明提供了一种储层酸化增注施工用螯合剂及其制备方法和应用。该螯合剂的原料组成包括：10.0％-20.0％的甲基磺酸，10.0％-20.0％的甲醇，10.0％-20.0％的聚天冬胺酸，10.0％-15.0％的环氧琥珀酸，5.0％-10.0％的十六烷基磺酸钠，10.0％-15.0％的十六烷基三甲基溴化铵和余量的水。本发明还提供了上述螯合剂的制备方法。本发明的储层酸化增注施工用螯合剂用于酸化增注施工中，可以有效溶蚀岩石裂缝，直接使用，无需反排。
摘要（英）：

The invention provides a chelating agent for acidification augmented injection construction of a reservoir, as well as a preparation method and an application of the chelating agent. The chelating agent comprises the following raw materials: 10.0-20.0% of methylsulphonic acid, 10.0-20.0% of methanol, 10.0-20.0% of polyaspartic acid, 10.0-15.0% of epoxy succinic acid, 5.0-10.0% of hexadecyl sodiumsulfonate, 10.0-15.0% of cetyl trimethyl ammonium bromide and the balance of water. The invention further provides a preparation method of the chelating agent. The chelating agent for the acidification augmented injection construction of the reservoir is used for the acidification augmented injection construction, can effectively corrode rock cracks, and is used directly and does not need to be discharged reversely.
