| 摘 要： | 根据塔里木H工区碳酸盐岩孔洞储层的地质地震综合解释成果,通过改进地震物理模型制作工艺,构建了一个与该区实际地层参数相近的三维碳酸盐岩孔洞储层精细物理模型。严格按照实际地震资料的采集参数和处理流程对物理模型进行了地震数据采集和处理,获得了与实际地震数据相匹配的物理模型地震数据体。最后,对孔洞储层的纵向分辨率、横向分辨率以及孔洞储层体积校正等问题进行了讨论:认为阻抗反演可有效提高孔洞储集体纵向识别能力;从物理模型研究的角度得到横向识别多洞的最小距离;利用物理模型数据建立了孔洞储集体校正量板,有助于实际孔洞储集体体积的估算。

| Abstract: | We present here our research on seismic physical model of carbonate cavern reservoir. First a three-dimensional cavern physical model is built with parameters similar to practical counterparts based on geological seismic interpretation of carbonate cave reservoirs in the H area, Tarim Basin. Then seismic data of physical model is obtained according to practical seismic data acquisition and processing procedures. Finally, vertical and horizontal resolution and cave volume calibration are analyzed. Impedance inversion can effectively improve the vertical resolution of caves. Minimum cave horizontal distance which can be identified is obtained from model analysis. The relationship between seismic attribute volume and real cave volume is analyzed. Calibration templates for reservoir volume estimation are generated to estimate fracture-cavern reservoir volume on seismic data. |
