摘要：为了在有限空间内深索具有大通流面积、高压损特性的注水嘴，使其在注水过程中保证配水精度的同时具有良好的防措能力，应用TRIZ创新理论对具有高压损、防增特性的分层注水水嘴进行了深入分新和优化设计。通过功能及冲突矩阵分析，利用结构嵌套法对水嘴结构进行优化，并设计出具有嵌套形式的新型绕流对冲水嘴。通过数值模拟方法对新型水嘴的压损特性进行分析，结果显示，新型水嘴可在保证截面面积较大（不小于传统①4.0mm直孔的通流面积)的情况下提供优于传统 02.0mm直孔水嘴的压损特性，从而可在保证配水准确性的同时提升防堵能力，提高水嘴的免维护周期。

Abstract: It is aimed at exploring the water injection nozzle which is characterized by large flow area and high pressure loss in limited space, so as to ensure water allocation accuracy and good anti-blocking capacity in the process of water flooding recovery. The TRIZ innovation theory was applied to perform thorough analysis and optimal design on separate layer water injection nozzle which has the performance of high pressure loss anti-blocking. Based on function and collision matrix analysis, the water nozzle was structurally optimized by means of the structure nesting method, and a novel bypass reverse water nozzle with the nesting form was designed. And its pressure loss characteristic was analyzed by using numerical simulation. It is indicated that this novel water nozzle is superior to the traditional O2.0 mm straight hole nozzle in term of pressure loss characteristic while its cross section area is remained larger (not smaller than the flow area of traditional O4.0 mm straight hole). And thus, the anti-blocking capacity of the water nozzle is improved and its maintenance free cycle is extended while the accuracy of water allocation is guaranteed.
