| 摘 要： | 依据地震、钻井、测井资料,详细分析了双辽断陷内火石岭组、沙河子组和营城组的岩性、电性及地震反射特征.双辽断陷从岩性上看火石岭组由凝灰岩、火山角砾岩、砂砾岩组成;沙河子组主要由灰色泥岩与细砂岩、砂砾岩组成;营城组主要由泥岩与粉细砂岩、砂砾岩组成.从电性上看火石岭组为电阻中到高值,声差低值;沙河子组以一套较连续的弱反射或空白反射为特征;营城组与岩性组合特征一致.从地震剖面上看火石岭组构造高部位为强反射,其下可见削截,其上可见上超现象;沙河子组为由杂乱反射变为空白反射或较连续平行反射;营城组上下为低频、强振幅较连续反射,中部体现弱振幅、空白反射中低频特征.

| Abstract: | On the basis of seismic,drill hole and well logging data,the Houshiling,Shahezi and Yingcheng formations in Shuangliao fault depression are analyzed on the lithological,electric and seismic reflection characteristics.Lithologically,the Huoshiling Formation is composed of tuff,volcanic breccia and sandy conglomerate; Shahezi Formation,composed of gray mudstone,fine sandstone and sandy conglomerate; while the Yingcheng Formation,silty sandstone and sandy conglomerate.The electrical resistivity of Huoshiling Formation shows medium to high value.The Shahezi Formation is characterized by continuous weak reflection or blank reflection.The electrical characteristics of Yingcheng Formation are consistent with the lithologic assemblage.In the seismic profiles,the structural high of Houshiling Formation shows strong reflection.The Shahezi Formation presents chaotic reflection to blank reflection or continuous parallel reflection.The Yingcheng Formation shows continuous strong reflection with low frequency in the top and bottom,while weak blank reflection with low to medium frequency in the middle part. |
