济阳坳陷义和庄古潜山溶蚀、裂缝发育带灰色-遗传识别

GRAY-HEREDITY IDENTIFICATION OF UPGROWTH ZONES WITH SOLUTION AND FISSURES OF JIYANG SAGS IN YIHEZHUANG PALEOZOIC BURIED HILLS

通过对裂缝识别测井、声波测井、深浅双侧向测井求取溶蚀和裂缝带发育参数裂缝张开度、裂缝孔隙度、裂缝渗透率、地层系数、残余岩溶强度指数和裂缝发育指数 ,并结合岩芯观察和录井资料 ,给出控制特征参数 ,建立潜山灰岩储层单井溶蚀、裂缝带模式图。在此基础上 ,应用灰色 -遗传过程识别系统对义和庄潜山三维地震资料进行溶蚀和裂缝带识别 。

The authors get upgrowth parameters of the fissure solution zones - the opening, porosity, permeability, upgrowth exponent of the fissures, the stratigraphic coefficient, and remaining karst strength by fissure identification, logging, sound logging and deep shallow double laterologging, present the controlling characteristic parameter and build the model of solution and fissure zones of limestone reservoir single well by combining core observations and logging. By using the identification system of process of gray heredity, the authors identify the solution and fissure zones from 3D seismic data of the Yihezhuang buried hills and predict the favorable zones for reservoir development.
