目前测定工地油石比的方法,一般是取样在室内用抽提仪进行抽提,或用煤油加热溶解反复进行清洗。这两种方法均比较费时,在试验时还会放出一些有害气体。为了避免这种现象,本文提出用视比重法测定工地油石比以供参考。一、基本原理视比重法测定工地油石比的基本原理是:事先配制比差为0.5％的五个油石混合料试样,其中要有两个大于和两个小于设计油石比,分别测出每个油石试样的视比重
At present, the method for determining the ratio of oil to rock in a construction site is generally taken by sampling in an indoor extraction apparatus or by heating and dissolving with kerosene repeatedly. Both of these methods are time-consuming and emit some harmful gas when tested. In order to avoid this kind of phenomenon, this article proposes to use the apparent gravity method to determine the site oilstone ratio for reference. First, the basic principle Depending on the gravimetric method to determine the ratio of oil and gas on the site of the basic principle is: pre-formulated ratio of 0.5% of the five oilstone mixture samples, which should have two greater than and two less than the design of oilstone ratio were measured Depending on the proportion of a whetstone sample
