径向水力喷射射孔技术在国内经过了十几年的研究与应用,取得了良好效果,尤其在致密低渗透油藏效果更佳,平均增产达1—3倍;而常规射孔深度有限,难穿透污染带,易产生压实带及二次污染。特别是低渗特低渗油藏更严重,高效开采和动用难度很大。本文对径向射流射孔技术进行了阐述,对其在现场的应用进行了分析研究。 Radial hydraulic jetting perforation technology in the country after more than 10 years of research and application, and achieved good results, especially in a more effective low-permeability reservoirs, an average increase of 1-3 times; conventional perforating depth is limited, Difficult to penetrate the pollution zone, easy to produce compaction zone and secondary pollution. Especially the low-permeability and low-permeability reservoirs are more serious and highly efficient mining and utilization is very difficult. In this paper, the radial jet perforation technology is described, and its application in the field is analyzed.
