| 摘 要： | 研究了金湖凹陷铜城断裂带阜宁组低渗透储层，该区阜宁组具有沉积物偏细、孔喉半径小、储层物性差的特点。对影响砂岩储层物性的主要因素进行了分析，认为成岩作用、泥岩欠压实、沉积环境、流体活动、裂缝是主要的控制因素，并对储层改造效果进行了分析。

| Abstract: | The characteristics of low permeability reservoirs of Funing Formation in Tongcheng fault zone of Jinhu depression are stated: they are thin sediment, small pore throat size, low porosity and permeability. In view of those characteristics, the authors analyze the mechanism of low permeability reservoirs and think that the main causes are diagenesis, mudstone lesscompaction, sedimentary environment, fluid flow, fracture. |

| Keywords: | Tongcheng fault zone Low permeability reservoirs Diagenesis Mudstone ill-compaction Fluid flow Fractures Jinhu Jiangsu |
