摘　　要：　江汉油区盐间非砂岩油藏具有较大的增产潜力,但产量递减快,容易导致油井近井地带碳酸盐结垢。为了提高增产效果,必须认识分析盐间非砂岩酸化机理,对盐间非砂岩油层酸化工艺、施工工艺进行改进。There is great potential in oil production increase of insert salt layers nonsandstone reservoirs in Jianghan Oil Region,but the oil production declines very quickly,which is easy to cause the carbonate scaling near-well-bore. To enhance the effect of increase oil production,the acid treatment mechanism for insert salt layers nonsandstone reservoirs must be recognized and analyzed,and the acid treatment technology and construction technology for insert salt layers nonsandstone reservoirs must be improved.
