| 摘 要： | 线性体密度是一种反映断裂裂缝带等线性构造密集程度的参数,最初用来分析探测矿产及能源赋存和工程地质及地震地质的构造条件,后用来预测现今岩溶系统中连接落水洞和岩溶泉的洞穴路径。针对目前地震属性预测洞道的主观性和不确定性,以塔里木盆地轮古油田中斜坡区奥陶系岩溶洞道为研究对象,运用以反映断裂信息的蚂蚁追踪属性为基础,裂缝的各向异性和地层倾斜方位为约束条件的线性体密度法,在地震振幅属性预测洞道的基础上,通过线性体密度验证并修正该结果,使岩溶洞道的预测更准确且有据可循,最终将有效地指导碳酸盐岩储层的勘探与开发。

| Abstract: | Lineament density,a kind of parameter reflecting the intensity of linear structur,is used to analyze the occurrence in mineral products and energy,the tectonic conditions of engineering geology and seismogeology initially.It is then used to predict the conduit path connecting the swallow holes and karst springs.Because of the subjectivity and uncertainty in predicting cave conduit using seismic attributes,this paper takes Ordovician karst cave conduit in Zhongxiepo area,Lungu Oilfield as the research object and,proposes a lineament density method based on fracture information calculated by ant-tracking and constrained by anisotropy of fracture and dipping-azimuth of bedding plane.The cave conduit prediction can be more accurate and effective by linearment density correction of the prediction by seismic attribute,and eventually will guide the exploration and development of carbonate reservoirs. |
