摘要

射流喷嘴是水力射孔压裂工具的核心部件，喷嘴结构的设计直接影响射孔效果和效率。本文采用SST k- ω湍流模型计算了水力射孔喷嘴的流场特性。结果表明，喷嘴结构参数对射流性能有显著影响。通过正交实验，初步优化了锥形-圆柱形喷嘴的几何参数为:圆柱形段直径为6 mm，收缩角为10°，收缩段长度为8 mm，圆柱形段长度为12 mm。研究结果可为后续射流破岩试验研究和射流工具的优化设计提供理论指导。

Jet characteristics and optimal design of hydraulic perforating nozzles for natural gas hydrate reservoirs

Jet nozzle is a core component of the hydraulic perforating fracturing tool, and the design of the nozzle structure directly affects the perforating effectiveness and efficiency. In this paper, the flow field characteristics of hydraulic perforating nozzles are calculated by the SST k- ω turbulence model. The results show that the nozzle structure parameters significantly influence the jet performance. Through orthogonal experiments, the conical-cylindrical nozzle geometric parameters are preliminarily optimized as follows: the cylindrical segment diameter is 6 mm, the contraction angle is 10°, the contraction segment length is 8 mm, and the cylindrical segment length is 12 mm. The results can provide theoretical guidance for later experimental research on jet rock breaking and optimization design of the jet tools.
