| 摘 要： | 通过分析研究鄂尔多斯盆地中南部姬塬地区地震剖面上多期进积砂岩叠加的地震前积异常现象，从已知井的层序对比分析人手，通过地质建模及模型正演等方法建立地震解释模式，采用层序地层学的解释方法，利用二维沿沟弯线地震资料，对研究区三叠系延长组长7-长4＋5期砂体的成因以及湖盆的变迁进行了探索性预测研究，为后续研究该区各期湖盆的演化及三角洲沉积体系的展布提供依据。 |

| Abstract: | The seismic progradation abnormal phenomena on polyphase progradation sandstone superimposed was studied, which is in Ji Yuan area＇s seismic profiles in southern - central regions of the Ordos basin. The seismic interpretation pattern was set up by analysis of the phreatic matching of successions as well as geological modeling and forward modeling methods. The basis of the follow- up study were provided , it was about the evolutions in lake basin and the throughgoing of delta sedimentary system, through using sequence stratigraphy interpretation method and crooked line along the ditch seismic data and studying the origin of the Triassic Yan Chang Chang7 - Chang4 ＋ 5 aera＇s sandbody. |
