地质相 meaning in Chinese
geofacies
geologic facies
Examples
- To distinguish oil layers of low resistivity through combining well logging with geologic facies
测井和地质相结合识别低阻油层 - The basic principle and method of 3d stochastic modeling of sedimentary microfacies are discussed according to geological and acoustic impedance data of well - logging constrained seismic inversion , and a case study according to stochastic modeling of fluvial facies reservoir of the minghuazhen formation of neocene in a certain block of bohai bay basin is used to show the general process of this research
摘要探讨了综合应用地质及测井约束地震反演信息进行三维沈积微相随机建模的基本原理、思路与方法， ?以渤海湾盆地某区块新近系明化镇组河流相储层?例，说明这一研究过程的基本步骤，包括井眼沉积微相解释、测井约束地震反演、波阻抗与地质相的概率关系分析、随机模拟方法选择、地质统计特徵分析、三维随机建模、随机模拟预测的多解性评价。 - On the basis of areal geological background , the distribution pattern of sedimentary microfacies in the chang - 6 oil - bearing beds was distinguished and the palaeogeographic environment was reconstructed by the analysis of geology facies , logging facies , stratum thickness , sandstone thickness and sandstone percent and other sedimentary characteristic . the method of digital sedimentary microfacies was applied in part of the research area for the first time , and acquired the satisfying effect . the digital sedimentary microfacies realized the description of the sedimentary evolution from chang - 62 to chang - 61
在区域沉积背景的墓础上，结合地质相特征与测井相分析，对地层厚度、砂体厚度以及砂地比(砂岩含量)等在平面上的分布规律进行了综合分析，并结合沉积序列与沉积特征等，判别了沉积微相在平面上的分布格局，恢复出长6油层组各沉积期的古地理环境。
