【摘要】：沉积过程的分析是从沉积成因角度恢复和再现地质体的沉积演化过程,同时是阐明沉积地质体形成机理的重要研究手段。基于沉积过程的储层表征以沉积成因为切入点,通过合理的重建储层沉积过程表征储层,更有利于储层形成机理的研究。近年随着沉积学的发展及相关学科科学技术的进步,沉积过程的研究呈现全面发展的态势:利用现代沉积提供的不同时段沉积影像资料,获取不同时期沉积特征进而重建连续的沉积演化过程;通过物理沉积模拟实验,在短时间内再现和重建沉积过程;利用数值模拟方法,在给定合理参数的前提下定量模拟沉积过程;利用露头结合探地雷达,精细刻画储层内部结构,进而探讨沉积过程理解储层形成机理;在地下密井网条件下,应用多井所揭示的沉积构型特征及其之间的关系,结合地震连续切片成果,明确储层三维空间展布,在沉积学原理指导下恢复其演化过程。各种研究方法为储层沉积过程的研究提供了技术支持,同时各方法又存在其自身的不足,有待进一步完善。今后储层沉积过程的研究应在完善各研究方法的基础上不断融合发展,综合多方面的资料,借鉴不同方法所给予的启示,最终合理的重建沉积过程更好的表征储层并揭示储层形成机理。
[Abstract]:The analysis of sedimentary process is to restore and reproduce the sedimentary evolution process of geological body from the point of view of sedimentary genesis, and it is also an important research means to clarify the formation mechanism of sedimentary geological body. The reservoir characterization based on sedimentary process takes sedimentary origin as the breakthrough point, and it is more advantageous to study the formation mechanism of reservoir through reasonable reconstruction of reservoir sedimentary process. In recent years, with the development of sedimentology and the progress of science and technology of related disciplines, the research of sedimentary process has developed in an all-round way. Acquire sedimentary characteristics of different periods and reconstruct continuous sedimentary evolution process; reproduce and reconstruct deposition process in a short time by physical deposition simulation experiment; use numerical simulation method, Under the premise of reasonable parameters, the sedimentary process is simulated quantitatively, the internal structure of the reservoir is accurately described by outcrop combined with ground penetrating radar, and the formation mechanism of the reservoir is understood by the sedimentary process. Under the condition of underground dense well pattern, the formation mechanism of the reservoir is discussed. With the application of the sedimentary configuration characteristics revealed by multi-wells and the relationship between them, combined with the results of seismic continuous slicing, the three-dimensional spatial distribution of reservoir is defined, and the evolution process is restored under the guidance of sedimentology principle. All kinds of research methods provide technical support for the study of reservoir sedimentary process, and at the same time, each method has its own shortcomings, which need to be further improved. In the future, the study of reservoir sedimentation process should be integrated and developed on the basis of perfecting various research methods, synthesizing many aspects of data and drawing lessons from different methods. Finally, the reasonable process of reconstruction and deposition can better characterize the reservoir and reveal the formation mechanism of the reservoir.
