1·A well completion with no stimulation such as fracing or acidizing.
没有进行增产处理作业（如压裂或酸化）的完井。
2·In each case, the matrix acidizing treatment improves the formation permeability to enable enhanced production of reservoir fluids.
在每种情况下，基岩酸化处理改善了地层的渗透性，于是使储层流体的产量增加。
3·Sealing performance and operating life of the fracturing pump directly influence quality of the acidizing operation, and bad seal will result in great deal of maintenance work.
压裂泵柱塞密封性能好坏与使用寿命的长短直接影响压裂酸化作业的正常实施，密封不良将带来很大的维护工作量。
4·Foam acidizing is used on carbonate reservoirs, because it is more retarded and has better fluid-loss control than normal acid.
泡沫酸化用于碳酸盐储层，因为它与正常酸相比反应速度较慢而且防滤失性能较好。
5·The results show that with the fracture cleaning and acidizing, the productivity of the well has been greatly improved.
施工结果表明，通过裂缝清洗和酸化改造，该井产能得到了较大程度提高。
