以准噶尔盆地春光油田C23井区沙一段T1砂体为例，归纳、总结了沟谷控制的辫状河储层综合预测方法。即利用层位拉平技术恢复古地形，刻画沟谷边界及沟内古地貌特征；利用几何类地震属性和三维可视化技术解释断层分布；综合古地貌恢复、断层分布和地震属性分析，刻画辫状河的主河道分布；采用相对波阻抗的聚类分析刻画砂体分布；采用几何平均属性和标准偏差属性刻画储层分布。研究结果与现有钻井结果吻合较好。研究区的储层横向展布主要受沟谷控制，含油储集层主要集中在古地形深沟的辫状河心滩坝，其次是辫状河道砂体。

英文摘要：

Taking the T1 sand body in Member 1 of Neogene Shawan Formation in Well C23 area of Chunguang Oilfield in Junggar Basin as an example, this paper induces and summarizes the integrated prediction methods and techniques for the gully-controlling braided river reservoirs. The methods are described as follows. The horizon flattening technology is used to restore the palaeotopography and further finely portray the ravine boundaries and palaeogeomorphology features in the valley for determining the scope of the valley and the exploration target area. The geometric seismic attributes, such as curvature, azimuth, maximum curvature and three-dimensional visualization techniques are used to interpret the fault distribution. The palaeogeomorphology recovery results, the fault distribution and the seismic attribute analysis are integrated to depict the main channel distribution of the braided river and further determine the beneficial reservoir development zones. The cluster analysis of the relative wave impedance is used to predict the sand body and determine the sand bodydistribution range. The geometric mean attribute and the standard deviation attrib portray the reservoir distribution. The research results fit well with the existing dril ute are used to ling wells. The results show that the valley controls the lateral distribution of the reservoir. And the reservoir is mainly distributed in the valley. The oil bearing reservoirs are mainly concentrated in the mid-channel bar of the braided river in the palaeotopographic deep groove, next in the sand bodies of the braided river
