摘要
应用碎屑岩地震相研究的理论和方法,对川中地区三叠系中、下统碳酸盐岩地震相进行了研究。地震相与沉积相的结合,通过地震剖面提供的各种参数解释环境背景和岩相条件,根据地震剖面上所通过的钻井岩相划分,使地震相、沉积相、钻井岩相分析融为一体,并在沉积和岩相研究方法上探索新的途径。
The seismic facies of the Middle and Lower Triassic carbonate rocks in central Sichuan are discussed with the aid of the theory and method of the seismic facies analysis of the elastic rocks, and the environmental background and sedimentary facies conditions are explained in terms of different parameters from the seismic profiles in combination with sedimentary facies analysis. The classification of the lithofacies of the boreholes through the seismic profiles results in the integration of the seismic facies, sedimentary facies and lithofacies analysis and new approach to study sedimentary facies and lithofacies.
