双复射孔技术是一种新型的射孔完井工艺技术,介绍了双复射孔技术的技术原理和技术特点,对其在侏罗系油藏中的实际应用效果进行了分析,并与常规射孔技术进行了对比。结果表明:对于地层系数低于100μm~2·m、物性相对较差且薄,而压裂、酸化改造风险又太大的底水油藏,采用该技术射孔增产效果显著,具有广泛的推广应用价值。
The double-perforation technique is a new perforation and completion technology. The technical principle and technical characteristics of the double-perforation technique are introduced, and its practical application effect in the Jurassic reservoir is analyzed. Conventional perforating techniques were compared. The results show that for bottom water reservoirs whose formation coefficient is less than 100μm ~ 2 · m, physical properties are relatively poor and thin, and the risk of fracturing and acidification is too high, this technique has a significant effect of perforation stimulation and has wide promotion Value.
