| 摘 要： | 利用地震相分析技术,结合岩心等资料研究了冷家油田沙三段沉积体系平面分布特征。根据冷家油田沙三段地震反射样式,可划分为斜坡、台地、凹地3种类型,共16种地震相。在圈定扇三角洲前缘和前扇三角洲相带的基础上,发现并圈定了滑塌沉积、湖心岛、砂坝、纵向扇、斜坡前积复合体、坡底扇、盆底扇、障壁体系等一系列单元。该区北部形成纵向三角洲,东部形成扇三角洲,西部形成斜坡前积复合体。

| Abstract: | With seismic facies analysis and core data, distribution of depositional system of the 3rd Member of the Shahejie Formation in Lengjia oilfield of the Liaohe Basin, is studied. According to seismic reflection structure, it can be divided into 3 types: slope, plat form and depressed area, including 16 seismic facies. Based on fan-delta front and pro-fan delta, slump deposition, island in the center of lake, sand bank, longitudinal fan, slope progradation complex, slope fan, sublacustrine fan and barrier system are found. Longitudinal delta is developed in the north, fan-delta in the east, and slope progradation complex in the west. |
