To braided stream deposit , the fluvial sand body is distribute largely and continuously , so the heterogeneity is poor relatively , the relation of injection and production is better in the case of rare wells , about all wells have come on water , only in some thin sandbodys or bad physical layers there is some low flooded strata 对辫状河砂体，平面上大面积连续分布，在平面及层内非均质性弱，在较稀的井网下注采关系就较完善，目前平面上几乎所有井点都已水淹，只有局部由于砂体厚度变薄，物性相对变差而存在一些低水淹部位。
Horizontal well technology , have another name called the well technology of radiation , sets up perpendicular well in the precipitation place , and direction horizontal well in the different degrees of depths of perpendicular well , make groundwater pass the horizontal well to flow into the collect water perpendicular well , take water out with the water pump again , in order to achieve the goal of reducing the groundwater 水平井技术，又称辐射井技术，是在降水场地设置集水竖井，于竖井中的不同深度和方向打上水平井点，使地下水通过水平井点流入集水竖井中，再用水泵将水抽出，以达到降低地下水的目的。
The fact that grain of sand is fine or silty , with thin layer and little - scale scours means that the water energy was low . grain analysis tells its transiting character between turbulent flow and drag flow with the same character as sub - fan . in the core , every sequence is positive rhythm and debris flow that is not developed in delta was also found 岩电关系分析表明，孔隙度与声波时差成正相关关系，与自然伽玛呈负相关关系，而渗透率与孔隙度具有较好的指数关系，据此建立了解释模型，在测井数据标准化的基础上进行了测井解释，较为准确地反映了井点处的物性特征。
( 4 ) it does not like the traditional method to suppose a special designated model concerns between well logging and seismic data . it gains a statistics relation from a series of data training and analysis , which _ is linear relation gained from multivariate regression or nonlinear relation gained from neural net training . ( 5 ) its most important characteristic is using the thought " alternation check " to evaluate the reliability of prediction , and can be used in the optimization of seismic attribute series 这就允许我们用到迭前和迭后地震数据经过非线性变换的信息: ( 4 )它不像传统做法那样在测井和地震之间假设一种特定的模拟关系，而是在对井点处一系列数据训练和分析中获得的一个统计关系，这个关系是通过多元回归获得的线性关系，或是通过神经网络训练获得的非线性关系: ( 5 )它最重要的特点是利用“交互校验”的概念来评估预测的可靠型，并能够用于地震属性系列的优化。
