| 摘 要： | 针对建南气田"低孔隙度、低渗透率、低压和非均质性强"的储层特征,采用水平井是高效开发的必要手段。经过综合分析12井次的水平井酸压效果,认为以胶凝酸为主的全程伴氮酸压工艺,适用于建南水平井的开发,达到了提高单井产能、提升开发效果的目的。

| Abstract: | Given the features of low porosity,low pressure,low permeability and strong heterogeneity typical of the reservoirs in Jiannan,the employment of horizontal wells in the exploration can raise the productivity with fewer wells.According to the analysis of the acid fracturing results obtained from 12 experiments with the horizontal wells since 2001,applying acid fracturing（primarily with gelling acid） in nitrogen has been able to meet the needs of production increase while adopting techniques based on different well performances could improve single well＇s productivity,achieve good performance of wells and economic benefits. |
