摘要
简述了水力喷射射孔的基本原理 ,介绍了喷管式、对称割缝式和 3孔固定式三种不同射孔工具的基本结构、工作原理和技术特点。在地面对喷管式和三孔固定式两种射孔工具做了试验 ,表明水力喷射射孔是一种高效的射孔手段 ,可满足油水井射孔需要。从 3种工具的现场施工效果看 ,大部分井经射孔后有明显的增油效果 ,有少数井效果不够理想的原因是 :对地质情况分析不透、工作介质选择不当 ,以及工艺设计不合理等。建议对水力喷射射孔工具的结构进行优化改进设计 ,合理选用工作介质 ,优化工作参数 ,认真研究井况 ,确定最佳射孔部位。
The basic principle of hydraulic jet perforators is introduced. The structur e, working principle and technical characteristic of three hydraulic jet perfora tors, i.e. the jet pipe type, symmetric slotted type, and 3-hole fixed type per forator, are described respectively. Surface test of the perforators shows that they can meet the operation requirements. Field use proves these jet perfor ators bring about remarkable increase of oil production. Suggestions are put for ward for improving the effect of the tool, including modifying the structure of the perforators, selecting proper working medium, optimizing operating paramete rs and deciding optimal perforating location.
