flood plain type-
In this paper, some characteristics of flow movement and sediment transport are analyzed by using the flume experiment data. the cross section of compound channel can be divided into four regions : the undisturbed region in main channel, the interactive region between channel and plain, the undisturbed region in flood plain and the boundary region. in the undisturbed regions, the distribution of longitudinal velocity along the depth has the feature of lograithmic. whereas, in the interactive region, the longitudinal velocity does not obey the logarithmic distribution law, but it can expressed as a revised logarithmic function by using a wake function. on the basis of the kinematic equation the velocity distribution of transverse velocity is obtained. in the boundary region, the longitudinal velocity obeys the law of parabolic distribution. furthermore, according to the simplified diffusion equation, the transverse distribution of sediment concentration in the interactive region is deduced. the analysis is in good agreement with the measured data
本文根據漫灘水流的運動特點，將漫灘水流的復式斷面分為主槽平衡區、灘槽交互區、灘地平衡區及邊壁區等4個區，並給出了各區寬度的經驗公式.根據灘槽交互區垂線流速分佈的變化特點，提出了附加尾流函數的對數流速分佈公式.在簡化水流運動方程和泥沙擴散方程的基礎上，對灘槽交互區內垂線平均流速及含沙量沿橫向分佈進行了理論分析，提出了反映灘槽水流動量交換強度的橫向渦量粘性系數及橫向擴散系數的表達式，得到了漫灘水流垂線平均流速及含沙量沿橫向分佈的解析解，並與實測資料吻合較好The paper analyzed sedimentary characteristics and depositional environment in t1f3 this region firstly, and on the grounds of establishing logical deposit pattern gave emphasis to make a study of distributing laws and spreading traits of the oolitic beach. because diagenesis is a vitally dominating factor that influenced oolitic beach reservoir nature in the region, the master diagenetic events of the reservoir in the lengthy geological history, as well as the influence to the pore abundance, was made a study of. the diagenetic stages and sequences were divided and the pore evolve pattern was established in the paper
本論文首先分析了研究區飛三段的沉積特徵與沉積環境，在合理建立沉積相模式的基礎上重點研究了鮞粒灘（壩）的分佈規律和空間展布特點；成巖作用是影響本區鮞灘儲集性至關重要的控制因素，論文詳細研究了儲層在漫長地質歷史過程中所經歷的主要成巖事件及其對孔隙發育的影響，劃分了成巖階段與成巖演化次序，建立了孔隙演化模式並以建南構造為例進行了成巖相展布研究的嘗試；最後還在鮞灘儲層基本特徵研究的基礎上對飛三段儲層進行綜合評價與預測。
