高孔密射孔工艺技术在渤海油田某区块的创新应用

High shot density perforation technology using offshore in Bohai

介绍了渤海油田某区块首次使用的一种新射孔技术,采用了比常规射孔孔密更高的射孔枪,并采取多种措施优化射孔枪稳定性,有效提高了单井产能,并采取配套技术降低近井地层污染。此技术在渤海油田某井的成功应用,相较同区块同层位邻井产能效果提升明显,并且可保持长期稳定的生产动态。

This paper introduces a new perforating technology frst time using offshore in Bohai . Compared to the conventional perforating it’s using high shot density perforating gun, and taking various measures to optimize perforating gun stability, effectively improve the single well production capacity. It also takes corresponding technology to reduce the pollution of the formation near the wellbore. This technique has been successfully applied in a well in the Jinzhou oilfeld. It’s more effective than the wells of the same formation in same area, and keeping long-term stable production.
