摘要
老油田重复酸化是油井增产和注水井降压增注的重要手段,本文对国内常用的各种酸液体系进行了介绍,分析了各种酸液体系在老油田的重复酸化效果,总结了各种酸液在老油田酸化中的优缺点,为后续的复重酸化提供参考。
Reacidizing is an important method in Plugging Removal of oil well as well as in reducing pressure and increasing injection of water well. In the paper, the domestic acid system in common use was introduced and the reacidizing effects were analyzed, the advantages and disadvantages of the domestic acid system in common use are summarized, which would provide a reference for the subsequent reacidizing work.
