Measurement theory of coaxial line phase water cut meter and flowing feature of water oil two - phase flow have been studied in this paper . and it has been found that the response of coaxial line phase water cut meter is not only related to water cut , but also related to temperature , salinity of formation water and flowing characteristics . based on soft - measuring theory and operating theory of the meter , soft - measuring model of coaxial line phase water cut meter has been set up with directly obtainable facts such as flux , temperature of oil and water mixture and salinity of formation water 本文在对同轴线相位法含水率计的测量机理和油井两相流动特性研究的基础上，揭示出同轴线相位法含水率计的仪器响应除了与油井含水率有关之外，而且还与油水混合介质的温度、地层水矿化度以及两项流动状态有关；结合软测量技术理论和同轴线相位法含水率计本身的测量机理以及与仪器响应有关的可以直接测量的流量、油水混合介质的温度、地层水矿化度等参数，建立基于同轴线相位法含水率计机理的软测量模型。
The two - dimension plane model and two - dimension vertical model developed have been used in practical projects , in which : in the flood simulation of daqing city , the two - dimension plane unsteady flow model has been built to fit in with the irregular river boundary and realize the rapid forecast of the water flow . in this model , the geographic information sys 在博斯腾湖大水体研究中采用平面二维水流与水质模型，可完全适应不规则的湖岸边界，考虑表面风应力，对吞吐量、风力、泵站位置、水位四种因素的多种组合情况下的博斯腾湖风生环流、矿化度分布及出流水质进行了模拟计算，获得了一些有意义的研究成果。
According to hydrochemistry monitoring material of northwest rivers in recent five years , and compared with the first northwest rivers water resources investigation appraisal result in 80 ’ s of last century , we analyzed the main rivers hydrochemistry condition , runoff degree of mineralization , total hardness and the hydrochemistry type distribution 根据近5a来对西北诸河的水化学监测资料，统计出了主要河流水化学状况；分析了河川径流矿化度、总硬度和水化学类型的地区分布，并与20世纪80年代第一次西北诸河水资源调查评价的结果进行了比较。
Chapter four , based on the trend analysis of the percentage of the number of fresh water and the total water with the increases of anion percentage of meq , have analyzed detailed that the influence increased and decrease of three major anion percentage of meq on tds of groundwater , and find out the different influencing section on percentage of meq 第四章中，以阴离子毫克当量百分数在不同区间内时的淡水水样个数与总水样个数之比随阴离子毫克当量百分数增加的变化趋势为基础，详细分析了三大阴离子毫克当量百分数对地下水矿化度增减的影响，并找出了不同影响段的毫克当量百分数区间值。
So it can better isoline draw process for analyzing mineralization result and groundwater hydrochemistry law of anion , cation distribution , it can also design and carry out superposing analysis function and use superposing method draw zone figure of hydrochemistry type . moreover , the system of secondary development has function that stores ultimate figure result into spatial database , it is not steady but flexible at any moment , it can so discretionarily superpose together with other figure layers that it forms synthesis figure set of multi - layer superposing and complicated content for the zone supplying accessorial support 该系统在完成了基本数据管理、图形显示及查询功能之外，还实现了等值线生成功能，大大简化了过去为分析矿化度、阴、阳离子分布等水化学规律而作的等值线绘制工作；该系统还设计实现了叠置分析功能，用于在等值线绘制功能的基础上，通过叠置分析的方法绘制出水化学类型分区图。
The better advantage of high frequency induction in defining thin intercalated bed , discerning high - salinity low - resistivity oil ( gas ) reservoir , estimative of reservoir , estimating water - flooded reservoir and so on are found by analyzing the application of the many frequency induction logs in shengli oil filed 通过分析胜利油田多口井的高频感应测井资料发现，高频感应在划分薄夹层、识别高矿化度低阻油(气)层、定性确定储层渗流能力、评价水淹层等方面都有明显的优越性。
The separation of gas and oil and water only limits to small system of gas pool and there are not separation of gas and water in the large bound . the border water is not active , the system of gas and water is small and driving power of water is poor . the degree of mineralization of strata water is lower , the type of water is sodium carbonate and respects the character of closing transition in the continent circumstance 油气水分异仅限于一个小气藏系统，不存在大范围的气水分异现象；气藏边底水不活跃，气水系统连通范围较小，水体驱动能量有限；地层水矿化度较低，水型以碳酸钠型为主，代表大陆环境下的封闭过渡带特征。
Chapter two through carrying on relativity analysis about tds and three major anion percentage of meq , percentage analysis of ranking on three major anion , have defined the existence of dependence between tds and three major anion , classified and laid the foundation for following water chemistry 第二章中，通过对矿化度与三大阴离子毫克当量百分数进行相关性分析，对三大阴离子毫克当量百分数作百分比排位分析，确定了矿化度与三大阴离子毫克当量百分数之间相关性的存在，为下面的水化学分类打下了基础。
