正常曲流河道与深水弯曲水道的特征及异同点
Characteristics,Similarities and Differences of Fluvial and Deep-Water Sinuous Channels
【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。
【Abstract】 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.However,the deep-water sinuous channels are very complex,important and valuable reservoirs in the exploration,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 advances 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.
【Key words】 fluvial channel; deep-water sinuous channel; submarine fan; sediment gravity current; architecture element; exploration and development of oil and gas;
