摘要

白云凹陷C16地区主要目的层受东北部东沙隆起碳酸盐岩台地影响,其砂体顶部灰岩广泛发育,且物性差异较大,传统的叠后波阻抗反演无法有效地区分砂岩、泥岩、灰岩,此外灰岩的物性情况是影响该区圈闭有效性和经济性的主要因素。结合区域地质背景及岩石物理分析,优选出密度与Mu-Rho交会组合作为岩性划分量版,并利用孔隙度与密度的相关性对灰岩物性进行预测,最终通过叠前同步反演技术得到目标区灰岩的物性分布特征,实钻结果表明,该技术具有较好的应用效果。

Abstract

Influenced by the carbonate rock platform of northern Dongsha uplift,the top of the main target formation sand-body reservoir at C16-field of Baiyun Sag develops a set of limestone deposition with greatly discrepant physical properties.Traditional post-stack AI can't distinguish sandstone,and shale with limestone effectively.Furthermore the physical properties of the limestone are the main factors influencing the validity and economy of the trap.Combined with the regional geological background and rock physics analysis,the density combined with Mu-Rho crossplot is selected as the optimum lithology classification template.Then the correlation between porosity and density was applied to predict the physical properties of the limestone.Finally,the distribution characteristics of carbonate rocks of the target zone were obtained through pre-stack simultaneous inversion technique.In addition,the actual drilling results demonstrate the validity of the technology.
