摘　　要：高能复合射孔技术以不同的高能能源为动力,实现对地层进行射孔和压裂的分步作功,在近井地带形成孔缝结合型超穿裂缝体系,从而提高产能. 该技术应用于哈萨克斯坦扎纳诺尔油田50 口生产井,产液量明显提高,工艺成功率达86%. 并针对施工过程中出现的问题提出了改进方法,进一步提高了工艺成功率.High energy composite perforation technology is a new technology for low porosity and low permeability reservoir. This technology uses different kinds of high energy as power and do work to formation by perforating and fracturing As a result, rift system will be formed and oil production will be improved. The technology has been used in 50 wells of Zanaruoer oilfield of Kazakstan with less investment but higher production, so it deserves to be generalized. Demonstrating on the problems arising in the process of utilizing, the paper proposes some practical remedying methods.
