摘要
超高压射孔技术可与酸化、压裂技术联作 ,用于灰岩及低压、低渗油藏 ,降低操作费用 ,提高采油指数 ;与防砂技术联作用于疏松砂岩油藏 ,可减少污染 ,改善防砂效果。从 16口超高压射孔完井的压力恢复曲线统计可知 ,14口井的表皮系数为负值。
Well completion technology associate with over-high pr essure perforati on and oil well stimulation is a new technology developing in abroad. The basic theory and the status of the technology are narrated. The process of the operati on is introduced. The over-high pressure perforation technology can associate wi th acidizing or fracturing, which can be used in carbonate reservoir and low pre ssure and low permeability pools. The technology can reduce operation fare and i mprove productivity index. The over-high pressure perforation technology also ca n associate with sand control technology, which can be used in unconsolidated sa ndstone reservoir. This technology can reduce pollution and improve sand control effects. From the pressure buildup curve of 16 wells who used over-high pressur e, the skin factor of 14 wells is negative.
