绝对渗透率 absolute permeability1. n. [Geology]The measurement of the permeability, or ability to flow or transmit fluids through a rock, conducted when a single fluid, or phase, is present in the rock. The symbol most commonly used for permeability is k, which is measured in units of darcies or millidarcies.岩石孔隙中只有一种流体（油、气、水）时测量的渗透率，常用符号K表示单位为达西 或者毫达西阿尔奇岩石 Archie rock1. n. [Formation Evaluation]A rock whose petrophysical properties are well described by the Archie equation with constant values for the porosity exponent and the saturation exponent. Such rocks typically have very little clay, a regular pore structure and high-salinity water. The term often is used to describe a rock that is petrophysically simple.孔隙度指数和饱和度指数为常量且其岩石物理特性能够用阿尔奇公式很好地描述的岩石。

这 种岩石通常具有很少的粘土，规则的孔隙结构和高矿化度的水常用于描述岩石物理特性简 单的岩石原生水 connate water1. n. [Geology]Water trapped in the pores of a rock during formation of the rock. The chemistry of connate water can change in composition throughout the history of the rock. Connate water can be dense and saline compared with seawater. Formation water, or interstitial water, in contrast, is simply water found in the pore spaces of a rock, and might not have been present when the rock was formed. Connate water is also described as fossil water.在岩石形成过程中包围在孔隙中的水。

也叫共生水粘土束缚水 clay-bound water1. n. [Formation Evaluation]Water within the clay lattice or near the surface within the electrical double layer. This water does not move when fluid is flowed through the rock. In the normal definition used by a log analyst, clay-bound water is not part of the effective porosity and is the difference between total and effective porosity. Clay-bound water is understood to include the interlayer water, although the contribution of the latter to the electrical properties of the clay may be different from the water in the electrical double layer.In the dual-water and the Hill-Shirley-Klein models, the volume of clay-bound water is related to the cation-exchange capacity per unit volume, Qv, by expressions that depend on the salinity and temperature of the electrolyte in which theclay is immersed. Direct measurement of the clay-bound water volume in the laboratory is difficult.粘土晶格内或者位于双电层靠近表面的水。

粘土束缚水在流体流经岩石时不发生移动交会孔隙度 crossplot porosity1. n. [Formation Evaluation]The porosity obtained by plotting two porosity logs against each other, normally density and neutron porosity. The computation assumes a particular fluid, usually fresh water, and particular response equations. The result is largely independent of lithology and is often a more reliable estimate of porosity than a single porosity log. It is often displayed as a quicklook log.通过两种孔隙度测井曲线交会得到的孔隙度，通常是密度和中子孔隙度交会压实校正 compaction correction1. n. [Geophysics]A change made to porosity measurements, such as those from sonic logs, to compensate for the lack of compaction, or the predicted loss of pore space as sediments are buried by overburden. Compaction corrections are commonly performed in uncompacted sediments.对孔隙度测量的一种变换，以补偿压实不足或者超压时预测的孔隙空间的减少。

压实校正通 常是对欠压实沉积岩进行补偿协调性刻度 compatible scales1. n. [Formation Evaluation]Scales for different logs that are chosen so that the logs will overlay in certain conditions. For example, a sandstone-compatible scale may have the neutron log scaled from 0.45 to -0.15 vol/vol and the density from 1.9 to 2.9 g/cm3 Then, in a pure quartz sandstone filled with fresh water, the two logs will overlay as the porosity varies.对于不同的测井曲线选择不同的刻度使得在特定的条件下这些测井曲线能够重合合成测井曲线 composite log1. n. [Formation Evaluation]A single log created by splicing together two logs of the same type run at different times in the well; or by splicing two different types of log run at the same time. For example, it is common practice to splice all the basic logs run over different depth intervals in a well to obtain a single composite record.将不同时间的同种测量的测井曲线或者同时而不同类型的测井曲线拼接在一起得到的单一 测井曲线。

有效渗透率 effective permeability1. n. [Geology]The ability to preferentially flow or transmit a particular fluid when other immiscible fluids are present in the reservoir (e.g., effective permeability of gas in a gas-water reservoir). The relative saturations of the fluids as well as the nature of the reservoir affect the effective permeability. In contrast, absolute permeability is the measurement of the permeability conducted when a single fluid or phase is present in the rock.当两种或者两种以上的流体通过岩石时，对其中某一流体测得的渗透率，有效渗透率又叫相 渗透率。

有效孔隙度 effective porosity1. n. [Geology]The interconnected pore volume or void space in a rock that contributes to fluid flow or permeability in a reservoir. Effective porosity excludes isolated pores and pore volume occupied by water adsorbed on clay minerals or other grains. Total porosity is the total void space in therock whether or not it contributes to fluid flow. Effective porosity is typically less than total porosity.2. n.
