稠油蒸汽吞吐井暂堵增能处理方法
摘要：
本发明提供了一种稠油蒸汽吞吐井暂堵增能处理方法，该方法包括：将一种由树脂小球与碳酸氢铵混合均匀后经压制成型而制成的固体暂堵材料送入油层下部1～2米处；由隔热管内正挤入由7～12%盐酸和3～6%氢氟酸配成的土酸；完成挤酸施工后，停泵0.5～1小时；开泵挤入顶替液或增能化学助剂；完成上述施工后直接进行注汽施工。本发明的稠油蒸汽吞吐井暂堵处理方法针对性强，施工简单，多效合一，成本低廉，能带来显著增能的效果。
摘要（英）：

The invention provides a temporary plugging and energizing treatment method for heavy oil steam-stimulated wells. The method includes: delivering solid temporary material, which is made by well mixing resin spheres and ammonium bicarbonate and pressing, to the position 1-2m below an oil layer; squeezing mud acid prepared with 7-12% hydrochloric acid and 3-6% hydrofluoric acid into an insulation tube; after squeezing, stoping a pump for 0.5-1 hour; starting the pump to squeeze displacement liquid or energizing chemical aid; directly performing steam injection. The temporary plugging and energizing treatment method for heavy oil steam-stimulated wells is highly purposeful, construction is simple, multiple effects are integrated, the cost is low, and energizing effect is significant.
