摘　　要：减轻剂在固井低密度水泥浆中发挥着重要作用,这类材料质量的好坏对固井质量的影响较大,严格其质量检测是把好固井质量的重要因素之一。密度作为减轻剂的主要指标,其测定准确率至关重要,在目前执行的检验标准中,密度小于1.0 g/cm^(3)类减轻剂的密度测定方法存在一些问题,操作性差,检验准确率低,不利于产品质量的控制。通过研究,改进了此类产品用李氏密度瓶测量密度的方法,设计两种挡塞,一种是滤网挡塞,一种是海绵挡塞,有效提高了这类减轻剂密度测定的准确率,对材料质量控制起到重要作用。Reducers play an important role in cementing low-density cement slurry.The quality of these materials has a great influence on cementing quality,and strict quality inspection is one of the important factors to improve cementing quality.density as the main indicator of reducers,it is very important for the detection accuracy,In the current inspection standards,there are some problems with the density measurement method for reducers with a density less than 1.0 g/cm^(3).The method is difficult to operate and has a low accuracy rate,which is not conducive to the control of product quality.Through research,the method of measuring the density of such products using Lee's density bottle has been improved.Two types of stoppers have been designed,one is a filter mesh stopper and the other is a sponge stopper,which effectively improves the accuracy rate of the density measurement of these reducers and plays an important role in the control of material quality.
