Progress of research on gas - water two - phase percolation and application in water - drive gas reservoirs 水驱气藏气水两相渗流及其应用研究的进展
Technical specification for integral pouring concrete filter floor and adjustable nozzle of air - water washing filter 气水冲洗滤池整体浇筑滤板可调式滤头技术规程
Most air space - heating systems also preheat domestic hot water through an air - to - liquid heat exchanger 大部分空气空间?加热系统也会通过气水热交换器预加热家庭里的热水。
Most intriguing in the central basin is the inverted gas - water position , abnormal low initial water saturation , slippage effect and evident non - darcy flow 并在深盆气藏中可能出现气水倒置、反常低的原生水饱和度、滑脱效应及明显的菲达西流动效应。
The character of the reservoir is typical of low permeability , high stress - sensitive , high capillary pressure value , steep capillary pressure curve , high critical water saturation , blur gas - water contact 物性特徵表现为渗透率低且对应力敏感，毛管压力高，毛管压力曲线陡峭，临界水饱和度高，气水界面模糊。
The fluctuation characteristics of liquid slug length in the downward inclined pipe with a large range of gas and liquid velocities were investigated on the basis of fractional theory of air / water slug flow 摘要利用非线性分析技术中的分形理论在较宽的流速范围内对下倾管中空气水段塞流的液塞长度波动特性进行了研究。

( 3 ) the treatment result of no2 - n is good . when the influent concentration of no2 - n is 0 . 01 ~ 2 . 23mg / l , the effluent is less than o . lomg / l and the influence of temperature , hydraulic loading the total ratio of gas and water is small ( 3 )生物滤池对亚硝酸盐氮的去除效果比较好，试验期间，水源水中亚硝酸盐氮浓度范围为0 . 01 2 . 23mg / l ，出水浓度一般低于0 . 10mg / l ，水温、滤速、气水比对亚硝酸盐氮的去除无明显影响。
By the study of logging result of 31 wells , it can be known that the development of gas layers are different in every well area , disperse in the portrait , and the relation of gas and water so complicates , the distribution of pure gas area is small , bound of connect is limited 结合测井解释结果对全区各层段砂层、气层的钻遇率、连通性的统计认为八屋气田各井区气层的发育程度差异较大，纵向上气层分散，气水关系复杂，纯气分布区域较小，连通范围有限。
