【摘要】：沉積過程的分析是從沉積成因角度恢復和再現(xiàn)地質(zhì)體的沉積演化過程,同時是闡明沉積地質(zhì)體形成機理的重要研究手段�；诔练e過程的儲層表征以沉積成因為切入點,通過合理的重建儲層沉積過程表征儲層,更有利于儲層形成機理的研究。近年隨著沉積學的發(fā)展及相關(guān)學科科學技術(shù)的進步,沉積過程的研究呈現(xiàn)全面發(fā)展的態(tài)勢:利用現(xiàn)代沉積提供的不同時段沉積影像資料,獲取不同時期沉積特征進而重建連續(xù)的沉積演化過程;通過物理沉積模擬實驗,在短時間內(nèi)再現(xiàn)和重建沉積過程;利用數(shù)值模擬方法,在給定合理參數(shù)的前提下定量模擬沉積過程;利用露頭結(jié)合探地雷達,精細刻畫儲層內(nèi)部結(jié)構(gòu),進而探討沉積過程理解儲層形成機理;在地下密井網(wǎng)條件下,應(yīng)用多井所揭示的沉積構(gòu)型特征及其之間的關(guān)系,結(jié)合地震連續(xù)切片成果,明確儲層三維空間展布,在沉積學原理指導下恢復其演化過程。各種研究方法為儲層沉積過程的研究提供了技術(shù)支持,同時各方法又存在其自身的不足,有待進一步完善。今后儲層沉積過程的研究應(yīng)在完善各研究方法的基礎(chǔ)上不斷融合發(fā)展,綜合多方面的資料,借鑒不同方法所給予的啟示,最終合理的重建沉積過程更好的表征儲層并揭示儲層形成機理。
[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.
