摘　　要：研究了ZD-10酸压暂堵剂的作用机理与使用性能,并在普光气田304-1井酸压施工中进行了试验应用。试验结果证实:该暂堵剂具有悬浮稳定性能好,对地层封堵后形成的突破压力高、封堵能力强,经残酸解堵后渗透性恢复率高等特点。经在普光气田304-1井酸压施工的试验应用,有效地实现了暂堵和酸压转向作用,取得了日产天然气30.58×104 m3的良好效果。The mechanism and performance of ZD - 10 pressure temporary plugging are studied, the acid pressure testing application in puguang gas field 304 - 1 well are researched. The result shows the tempo- rary plugging has good suspended stable performance, high breakthrough pressure to formation plug, strong sealing capacity, higher recovery rate after residual acid solution plugging premeabihy et al. After testing application in paguang gas 304 - 1 well acid pressure construction, the streering role of temporary plugging and acid pressure are implement effectively,abtains the nissan gas 30.58×104 m3.
