水泥自同步直线振动筛

针对目前固井水泥中结块、杂质等过多，严重影响固井质量的问题，根据钻井液直线振动筛的工作原理，研制出水泥自同步直线振动筛。经过一年多的跟踪监测及现场操作人员反馈的信息表明，这种振动筛可除去水泥中直径８ｍｍ以上的结块与杂质，提高了固井水泥的质量；工作效率提高了近６７％；减轻了工作人员的劳动强度，改善了工作环境；过滤筛网和激振电动机工作性能可靠，使用寿命长。

Development and application of cement self-synchronizing reciprocating line shale shaker

In view of foe problem that excessive impurity and agglomeration in the cement have great influence on the quality of well cementing, a cement self-synchronizing reciprocating line shale shaker is developed based on the working principle of drilling fluid straight line shale shakers. Field use and monitoring show that, the cement shale shaker is capable of re moving agglomeration and impurity with a diameter of 8mm, thereby can improve cementing quality; and it can reduce the labour intensity of the workers and improve the working environment with 67% increase of working efficiency; the screen and vibrating motor performance reliably and have long service life.
