中文摘要：

深水弯曲水道是深水扇的重要组成部分，又是深水油气勘探、评价与开发过程中十分复杂且备受重视的储集体。近10年来，随着高分辨率三维地震数据的应用、现代深海调查、古代露头以及实验流体数值模拟的研究，在深水水道沉积体认识方面不断有新进展和新发现，陆续在西非、巴西和墨西哥湾等地发现了大型深水油气田。简述了正常曲流河道与深水弯曲水道两种沉积环境在形成背景、岩性特征、成因机制、地震响应特征（外部形态与内部结构）、沉积充填演化以及流体流变学特征等方面的异同点。

英文摘要：

The deep-water exploration of oil and gas has become a focus of the exploration and development for oil and gas around the world, also the inevitable tendency of the hydrocarbon industry in future. How- ever, the deep-water sinuous channels are very complex, important and valuable reservoirs in the explora- tion, appraisal and development. With the researches on the high-resolution 3D seismic data of subsurface, the modern deep-water surveys, ancient outcrops and numerical simulation in the last decade, new ad- vances and discoveries are made in the knowledge of deep-water sinuous channels, and some giant oil and gas fields are found in West Africa, Brazil, Gulf of Mexico. There are differences and similarities between fluvial and deep-water sinuous channels about backgroud, lithology, genetic mechanism, sesimic reflection （external and internal character）, deposit-fill evolution and flow rheological properties et al.
