我国各主要油田已经多年开发，高渗透地层油开采殆尽，提高低渗透地层的采收率显得尤为迫切。本文从酸化暂堵剂和深部酸化用剂两方面对改造低渗透地层的措施进行了综述。通过暂堵转向剂的应用，使酸液进入低渗透层，增大地层渗透率，提高采收率。泡沫酸、稠化酸、乳化酸、自生酸、化学缓速酸等体系的研究开发使高温井中低渗透层的改造变为可行。
China’s major oil fields have been developed for many years, high permeability formation oil depleted, it is particularly urgent to improve the recovery of low permeability formations. In this paper, the measures of rebuilding low permeability formation are summarized from two aspects of acid blocking agent and deep acidizing agent. By temporary blocking agent application, the acid into the low permeability layer, increase formation permeability, improve oil recovery. The research and development of foam acid, thickened acid, emulsified acid, acid and chemical retarded acid system make the transformation of low permeability layer in high temperature well feasible.
