| 摘 要： | 准噶尔盆地腹部侏罗系以隐蔽油气藏为主，地震资料在目的层分辨率较低、地震反射特征不清晰，制约了对该区的低幅构造、岩性圈闭的识别和评价.本文根据侏罗系的沉积特点，建立河流、（扇）三角洲沉积体系地质模型，制作尖灭体、透镜体、河道砂、浊积体等地质体的三维物理模型，通过实验测试方法，研究地层条件下岩石物理性质的变化特征，系统研究储层地球物理参数变化的总体规律，并结合测井资料，采用波场物理模拟方法，研究波场响应特征与储层参数变化之间的规律，分析各种情况下的波场特征、属性特征. |

| Abstract: | Subtle reservoir is the main hydrocarbon type of Jurassic in the central Junggar Basin. Lower resolution and faint reflection characteristics of seismic data restrict the identification and evaluation of low relief structures and lithologic traps in this area. In this paper, the geologic model of the river-delta sedimentary system was built according to sedimentary characteristics of Jurassic, and the 3D physical models of pinch-out structure, lithologic lens, channel and turbidite sand-body were made to research the characteristic changes of rock-physical properties under subsurface conditions and change rules of reservoir geophysical parameters by examination. Combined with well-log data, the relationship between wave-filed response characteristics and reservoir parameters changes has been studied via wave-field physical simulation, the ulteriorly wave-field characteristics and attribute in various conditions were analyzed. |
