井震结合识别单一河道技术在M区块的应用

Application of Single Channel Identification Technology Combined with Well Seismic in Block M

摘要: 大庆油田扶余油层主要发育河流相沉积，受河流的摆动、湖水升降等影响，河道平面上具有一定的迁移性，不同河道砂相互切割、充填，单一河道识别相对困难。地震属性主要是利用数据体中抽取出的数据，反映出相应的地层信息，被广泛应用在油气田开发的各个过程中。本文主要利用RPS井震结合储层描述技术平台，提取原始地震振幅属性，同时根据砂体形态、厚度差异及其与测井曲线的对应关系，对M区块砂体展布特征进行预测，继而应用到单一河道识别当中，取得了较好的效果。

Abstract: The fuyu reservoir in Daqing Oilfield is mainly developed in fluvial facies deposits. Affected by the swing of rivers and the rise and fall of lakes, the channel plane has a certain migration. Different channel sands cut and fill each other, and it is relatively difficult to identify a single channel. Seismic attributes are mainly used to reflect the corresponding formation information by using the data extracted from the data body, and are widely used in various processes of oil and gas field development. This paper mainly uses the RPS well Seismic combined reservoir description technology platform to extract the original seismic amplitude attribute, and predicts the distribution characteristics of sand body in block M according to the shape and thickness difference of sand body and the corresponding relationship with the logging curve, and then applies it to the idzaientification of a single channel, and achieves good results.
