钻井泥浆的失水量是泥浆性能的一项重要参数。目前国内外使用的失水仪测得的是泥浆在静止状态下的静失水量,它不能反映泥浆在循环状态下的动失水量大小。为了研究泥浆动失水的规律,本文作者自行设计了动失水测定器,在本院工厂加工制成,经试验证明效果较好,可以用来测定泥浆的动失水量并研究其变化规律。 Drilling mud loss of water is an important parameter of mud performance. At present, the water loss meter used at home and abroad measures the static loss of water in the static state of the mud, which can not reflect the amount of water loss in the circulation of the mud. In order to study the law of muddy water loss, the author designed the lost motion water tester and processed it in the factory of our hospital. The result shows that the muddy water loss tester is better and can be used to measure the muddy water loss and to study its variation law.
