双复射孔技术是近几年发展起来的一项增效射孔完井工艺技术,并已取得较好的应用效果。本文介绍了双复射孔技术的工作原理、技术优点;结合河南油田B320井的应用情况表明:在地质条件下基本相同的情况下,采用该技术射孔,油层压裂施工时,破裂压力明显降低,加砂量增加;压后产液量增加,注水量提高。采用该技术射孔增产效果显著,具有广泛的推广应用价值。
Double perforation technology is a synergistic perforation completion technology developed in recent years, and has achieved good results. This paper introduces the working principle and technical merits of double perforating technique. Combining with the application of well B320 in Henan Oilfield, it shows that under the same geological conditions, the fracturing pressure is obviously Reduce, increase the amount of sand; pressure fluid production increased, increased water injection. Adopting this technology, the effect of perforation is obvious and it has a wide range of popularization and application value.
