搞好泥浆净化以降低固相含量,是实现钻井速度翻番的重要一环。据美国统计,如果泥浆的固相含量从14％降到0％,钻井速度就可提高40％,即泥浆的固相每降低10％,钻井速度就提高29％。因此,美国要求泥浆中的固相物保持在0.5％左右。苏联曾对在一般净化条件下泥浆泵易损件消耗量和应用旋流除砂器净化时泥浆泵易损件消耗量进行过对比,结果见表1。 Doing a good job of purifying the mud to reduce the solid content is an important part of doubling the drilling speed. According to U.S. statistics, the drilling rate can be increased by 40% if the mud’s solid fraction is reduced from 14% to 0%, ie the drilling speed is increased by 29% for every 10% reduction in the solid fraction of the mud. Therefore, the United States requires that the solid content in the mud be maintained at about 0.5%. The Soviet Union had compared the consumable consumption of mud pump under general purification conditions with the consumables consumption of mud pump when the cyclone desander was applied. The results are shown in Table 1.
