在低渗透油田勘探过程中,不断发展应用深穿透射孔和复合射孔新技术,能有效穿透钻井污染带,并对地层进行一定改造和解堵作用,两项技术的有机结合应用在油(气)层发现上起到了关健作用。重点对深穿透射孔技术、StimGun复合射孔技术的概念、工作机理进行阐述,通过近几年试油现场应用,取得了较好应用效果和实践认识,该射孔工艺施工简便、成本低廉、可实现多项工艺联合作业,取得了较好的应用效果。
In the process of low permeability oilfield exploration, the continuous development and application of deep penetration perforated and composite perforating new technology can effectively penetrate the drilling pollution zone, and the formation of a certain transformation and the role of plugging the two organic combination of technology used in oil (Gas) layer found to play a key role. The author mainly elaborates the concept and working mechanism of deep penetrating perforating technology and StimGun composite perforating technology. Through the application of on-site testing in recent years, it has achieved good application effect and practical understanding. The perforating process has the advantages of simple construction and low cost , Can achieve a number of joint operations, achieved good results.
