根据作者的经验,在注水设施上,似乎没有一种滤器是合算的。调查大量的注水过滤装置表明,注入水在未经过滤之前,就具备了较好的水质。本章准备充分解释过滤器的故障,并提出使用过滤器的一些条件。关于压力滤器及其运行状况和应注意的问题,很多资料已有说明,这里就不再重复了。在油田滤器装置的设计上,可利用的参数虽然已做了说明,但是滤器最适宜的使用范围并没有给出。不采取混凝和沉淀而单纯用过滤来除掉悬浮物和油是不太合理的。造价很高的压力滤器虽然安装得很好,但实际运行往往是失败的。很明显,把含有细小而分散的固体颗粒和油珠的水注入油层是不太合适的。这就提出了过滤问题。除了过滤是找不到直接、经济的有效解决办法的。通常采用的石英砂滤 According to the author’s experience, no filter seems to be cost-effective at waterflooding facilities. Investigating a large number of water filtration devices indicates that the injected water has good water quality before being filtered. This chapter is prepared to fully explain the failure of the filter and to propose some conditions for using the filter. A lot of information on the pressure filter and its operating conditions and should pay attention to the problem has been described here is not repeated. Although the available parameters have been described in the design of oilfield filter units, the most suitable range of filters is not given. It is not reasonable to simply remove the suspended solids and oil by filtration without coagulation and sedimentation. Although expensive pressure filters are well installed, actual operation often fails. Obviously, it is less appropriate to inject water containing fine, dispersed solid particles and oil droplets into the reservoir. This raises the issue of filtering. In addition to filtering can not find a direct, economical and effective solution. Commonly used quartz sand filter
