层内非均质性 meaning in Chinese
in-layer heterogeneity
Examples
- By using of the data of sedimentous microfacies , logging and cores , the text studies in - layer heterogeneity , between - layer heterogeneity and plane heterogeneity of the sand layers in the south part of n2 " reservoir in gasikule oil field of qinghai province
本文综合运用沉积微相、测井以及岩心分析等资料，对青海尕斯库勒油田n21油藏南区储层层内非均质性、层间非均质性以及平面非均质特征进行研究。 - The studies of in - layer heterogeneity are as follows : the text depicts the characteristics of heterogeneity by calculating the coefficient of variability , kmax / k and k . max / k . min of sand layers of different sedimentous microfacies ; divides interlayer into two types , and counts their numbers , thickness , frequency and density of a single sand layer according to the characteristics of lithology and logging , finally summarizes the characteristics of interlayer distributing ; sets up five in - layer heterogeneity models and points out that the primary models are model a and c . the studies of between - layer heterogeneity are as follows : the text depicts sand layers " growth and distributing conditions by calculating the lamination factor , sandstone density and overlap coefficient ; makes certain the lithology and thickness of interlayer by the method of contrasting the typical curves
层内非均质性研究，通过计算不同沉积微相砂体渗透率的变异系数、突进系数以及级差来说明主要储集微相的非均质特征；据岩性及电性特征，将层内夹层分为两类，统计单砂层段内夹层的个数、累积夹层厚度、夹层频率及夹层密度，并且根据夹层频率及密度平面分布图统计出每层的频率相对高值区和低值区，总结夹层分布特征；根据物性参数随深度的变化趋势建立了五种储层层内物性非均质模式，指出研究区内以a型和c型模式为主。 - To braided stream deposit , the fluvial sand body is distribute largely and continuously , so the heterogeneity is poor relatively , the relation of injection and production is better in the case of rare wells , about all wells have come on water , only in some thin sandbodys or bad physical layers there is some low flooded strata
对辫状河砂体，平面上大面积连续分布，在平面及层内非均质性弱，在较稀的井网下注采关系就较完善，目前平面上几乎所有井点都已水淹，只有局部由于砂体厚度变薄，物性相对变差而存在一些低水淹部位。 - Pi formation is combination of thick sand body , because the sediment mode of reservoir in changyuan of daqing is mainly combined of great leaf delta and partly fluvial facies , about 500m thick , combined of 130 little sand or mud layers , which is typical heterogeneity reservoir , the reservoir ' s character is greatly distribute , high permeate and serious heterogeneity
Pi油层组是厚油层组合，由于大庆长垣储层的沉积模式以大型叶状三角洲及部分河流相为主，总厚度500多米，由130多个小砂层和泥岩交互而成，是一套典型的非均质砂岩储层，该储层具有分布广、厚度大、渗透率高和层内非均质性严重等特点。 - 3 ) the sandbody distribution , physical properties , pore structure and heterogeneities are affected by the microfacies . at the center part of underwater distributive river course , the petrophysics and physical properties are both better than that at the edge of the microface . 4 ) the chang 61 2 - 3 substrata and the substrata of chang 62 " member which show the better porosity , permeability , and better pore structure ; display lower permeability variation coefficient , dart - coefficient and contrast - coefficient and good connecting sandbody so the horizontal heterogeneities is weaker ; whereas manifest stronger inner - heterogeneities due to the numerous intermediates ; present stronger inter - heterogeneities caused by the greater frequency of sandbody
长6储层中长6 _ 2 ~ ( 1 - 3 )和长6 _ 2 ~ 1砂层中的各个小层的孔隙度、渗透率值、含油性较好；平面非均质性较弱，表现为级差、突进系数、变异系数较低且砂体的连片程度高，钻遇率和连通系数较高；与此同时，层内非均质性较强，表现为垂向上夹层的数目较多，厚度较大；层间非均质性也较强表现为分层系数较高。
