- The present results indicate that the quantitative description of the non - dimensional mean lateral streak spacing + differs from the results previously published . the spacing + is not a constant value of 100 . it becomes larger as the reynolds number in terms of shear velocity increase
试验结果表明，低速带间距的无量纲数+并非为以往一致认为的100左右的常数，而是随摩阻雷诺数的增大而逐渐增大，在水力光滑区与摩阻雷诺数成二次方关系，在过渡区则为线性关系。 - The cross well seismic technology have been applied to ignite and receive inside the well , therefore , it overcame the effects of low weathering layers and increased the resolution by the scale of 10 - 100 times . this technique is capable of delineate the minimum sedimentary unit of the oil - bearing body and resolve the issues like : reservoir interconnection , dynamic monitoring and micro - structural description etc . in addition , it also provides the fine geological model for reservoir modeling and scientific evidence for the oilfield development plan designing
井间地震技术由于是在井中激发、井中接收，从而克服了地表低速带的影响，具有比地面地震高10 - 100倍的分辨率，能够达到分辨最小沉积单元油砂体的能力，因此该技术能够解决储层连通、动态监测、微构造描述等问题，并为油藏建模提供精细的地质模型，从而为开发方案的编制提供科学的依据。 - A series of experiments in a wider range of reynolds number were conducted for the investigation on the spatial and temporal distribution of the low - speed streaks in the near wall region of turbulent open channel flow . for the first time , the relationships between the spacing , the width , the length scale in the streamwise direction and the duration time of low - speed streaks and the reynolds number based on shear velocity were revealed
在水力光滑区和过渡区对明槽紊流近壁区的带状结构进行试验，测量并分析了带状结构的分布，首次揭示出低速带间距、宽度、纵向尺度及持续时间等随摩阻雷诺数的变化规律。
