随着油气勘探程度的加深、勘探技术的进步以及对油气资源需求的日益增长，一些埋藏较深、物性相对较差的储集层也越来越受到地质学家们的关注。经过数十年的勘探，许多油田中埋藏较浅、原生孔隙保存较好的优质储层已被广泛发现并投入生产，而埋藏较深、以次生溶蚀孔为主要储集层的较致密储层，正日益成为成熟探区勘探挖潜的重点。因此，寻找次生孔隙发育带的溶蚀孔隙甜点储层成为精细勘探的重要新领域。通过一些典型研究实例及大量研究成果的综述，从以下4个方面系统地阐述了溶蚀作用对储集层的改造：①溶蚀作用发生的成岩阶段；②溶蚀流体的类型；③溶蚀作用强弱的主控因素；④溶蚀作用对储集层的改造效果。近年来，已有较多的研究成果在溶蚀机理和对储集层的改造效果方面取得了重要进展，通过对这些主流观点的系统梳理，可对今后类似地质条件的研究提供重要的参考。

With the deepening of exploration degree, the progress of exploration technology and the increasing demands for oil and gas resources, some deep buried reservoirs with relatively poor physical properties have attracted more and more attention of geologists. After decades of exploration, many high-quality reservoirs with shallow burial and well-preserved primary pores have been widely discovered and put into production. However, deep buried tight reservoirs with secondary dissolved pores as the main reservoir space are increasingly becoming the focus of exploration in mature exploration areas. Therefore, searching for secondary pore development zones and dissolved “sweet” reservoirs will become an important new field for fine exploration in the future. Based on some typical case study and a large number of research results, this paper systematically expounded the modification of reservoirs by dissolution from the following four aspects:① diagenetic stage of dissolution; ②types of dissolution fluids;③main controlling factors of dissolution; ④ effect of dissolution on reservoir modification. In recent years, more and more research achievements have made important progress in dissolution mechanism and reservoir modification effect. The systematic analysis of these mainstream views has some reference value for similar geological conditions in the future.
