渗透率梯度测试仪是一种新型仪器 ,它能够在不破坏岩心原有结构的情况下 ,测出入井流体对岩心的影响深度和程度。用该仪器对酸化效果进行评价 ,获得了较好的效果 ,为优选酸液配方提供了理论依据。
The permeability gradient tester is a new type of instrument capable of measuring the depth and extent of core fluid impact on a well without breaking the original structure of the core. The acidification effect was evaluated by this instrument, and the better effect was obtained, which provided the theoretical basis for the optimization of acid formula.
