摘　　要：应用层序地层学对崖13－1气田主要产层陵水组三段进行了亚段细分，以此为基础，在地震阻抗剖面上得到不同亚段的阻抗体，利用层拉平技术将各亚段阻抗体抗平，并应用地质统计学方法求出各亚段阻抗体12个水平方向的变差函数，拟合其非均质性变程椭圆，通过对不同亚段变程椭圆的比较，结合沉积特征，分析了陵三段各亚段的沉积体系及物源方向。High resolution sequence stratigraphy is used to subdivide the main pay E 3 2l 3 in YC13 1 gas field into several units, and impedance volume for each unit can be got in seismic impedance profiles. Flattening technique is used to flatten impedance volumes of the units, and 12 horizontal variograms are obtained for each unit's impedance volume by geostatistics, with their anisotropy range ellipses fitted. By comparison among range ellipses of different units and in combination with depositional features, the E 3 2l 3 sedimentary system and provenance are analyzed.
