多级脉冲深穿透聚能射孔仪

Deep Penetrate Perforating System of Multi-pulse

多级脉冲深穿透聚能射孔仪是一种针对低渗储层开发的射孔器。通过聚能射孔技术和火药压裂技术的合理组合,一次下井可以完成一次聚能射孔和两次火药压裂3道工序。通过近200口井的现场应用证明,多级脉冲深穿透射孔可以有效解除射孔压实、钻井液侵入等对地层的伤害,改善油、气、水井近井地带的渗透能力,提高油井产出和注入能力。

The deep penetrate perforating system of multi-pulse is a new perforator for development of low permeability reservoir.It could perform three functions: one perforating and two fracturing,by organically combining jet perforation technique and propellants fracturing technology.Through field application in nearly 200 wells,the system is proved to be effective in relieving compaction,mud invasion and other damage to the strata,improving near-wellbore permeability of oil,gas and water wells,and thus enhancing oil output and injection capacity.
