【摘要】：深水沉积理论研究历经近70年历史,在分歧和争议中不断发展,一直是沉积学研究领域的热点问题。回顾深水沉积研究史,大体可将其分为3个阶段:(1)1950—1980年代的"浊流"与"浊积岩"时代;(2)1980—2000年代的深水牵引流发展及经典模式反思时代;(3)2000年至今的砂质碎屑流冲击和深水斜坡沉积模式时代。但时至今日,由于深水沉积过程本身的复杂性,深水沉积领域仍存在颇多争议和问题,主要集中在沉积物重力流术语的复杂混乱、深水牵引流沉积的识别评价及固定沉积模式与动态流体性质转换的分歧这3个问题上,深水沉积过程和流态转换的精确识别刻画及综合沉积模式的建立是当今深水沉积研究的难点。有效预测深水砂岩储层,发现更多深水油气资源是深水沉积研究的迫切诉求。今后的深水沉积研究应努力实现深水沉积概念术语的规范统一,同时注重地震沉积学应用,并大力发展实验模拟技术,多学科交叉发展,建立"源—渠—汇"综合及沉积流态有序转化的沉积模式,最终有效指导深水油气勘探。
[Abstract]:Deep-water sedimentary theory has been developing continuously in the field of sedimentology after nearly 70 years of history, and has been a hot issue in sedimentology. The history of deep-water sedimentary research is reviewed. It can be roughly divided into three stages: "turbidity current" and "turbidite" in 1950-1980 's; The development of deep-water traction flow and the era of reflection of classical model in 1980-2000 's; (3) the age of sand clastic flow impingement and deep-water slope sedimentary model from 2000 to present, but today, due to the complexity of deep-water sedimentary process, there are still many controversies and problems in deep-water sedimentary field. It mainly focuses on the complicated confusion of the terms of sediment gravity flow, the identification and evaluation of deep-water traction flow deposition and the divergence between the fixed deposition model and the dynamic fluid property transformation. The accurate identification and characterization of deep-water sedimentary process and flow transformation and the establishment of integrated sedimentary model are the difficulties in the research of deep-water deposition. The effective prediction of deep-water sandstone reservoir is very important. The discovery of more deep-water oil and gas resources is an urgent demand for deep-water sedimentary research. In the future, Deepwater Deepwater Sedimentary Research should strive to realize the standardization of Deepwater Deepwater Deposit terminology and pay attention to the application of seismic sedimentology. The experimental simulation technology is developed vigorously and the multi-disciplinary cross development is carried out to establish the sedimentary model of "source-channel-sink" synthesis and the orderly transformation of sedimentary flow, so as to guide oil and gas exploration in deep water effectively.
