目前钻井队普遍使用的泥浆筛,振动频率低,离心力小,筛布孔径大,除砂效果不好。这种情况不但加速泥浆泵配件的损耗,增加修泵时间,影响钻井速度,而且由于泥浆净化不良,井壁不干净,容易造成钻具阻卡。此外,工人捞泥浆槽和泥浆池的劳动强度也较大,加上泥浆筛结构不尽合理,还须用人工刮除堆积在筛布上的岩屑,因此筛布损坏较快,有时打 At present, the mud screen commonly used by the drilling crew has low vibration frequency, small centrifugal force, large aperture of the screen cloth and poor sand removing effect. This situation will not only accelerate the loss of mud pump accessories, increase repair time, affect the drilling speed, and because of poor mud purification, wall is not clean, easy to cause drilling resistance. In addition, the labor cost of workers fishing in the mud tank and the mud pool is also large. In addition, the structure of the mud screen is not reasonable, and the debris accumulated on the screen cloth must be scraped off manually so that the screen cloth is damaged rapidly and sometimes
