如何根据套管开窗侧钻定向小眼井的特点，选择合理射孔方式，有针对性研究小套管内施工作业的可操作性。在定向或水平小眼井条件下，采用不同工艺方式和工具组合，将射孔枪安全送入井下发射并顺利提出井口。在此基础上将研究的工艺应用于现场实践取得了令人鼓舞的地质成果，充分证明该项工艺技术广阔的应用前景。
How to select the reasonable perforation mode according to the characteristics of the small-borehole with side-drilled casing and to study the operability of the construction work in the small casing. Under the condition of small orifices of oriented or horizontal wells, the perforating guns are safely sent to the well for launching and the smooth wellhead is put forward with different combination of techniques and tools. On this basis, the study of the application of the field practice has achieved encouraging geological results, fully proved the broad application of the technology prospects.
