通常把泥浆中钙离子含量超过500ppm的泥浆称为高钙泥浆,在昆仑山前构造带钻井的泥浆,其钙离子含量普遍都高达上千ppm,有的井甚至高达上万ppm,作者简析了山前构造带超高钙泥浆的成因并提出了相应的对策。 Slurries containing more than 500 ppm of calcium in the slurry are often referred to as high-calcium slurries. Slurries constructed before drilling in the Kunlun Mountains generally have levels of up to thousands of ppm of calcium and up to some 10,000 ppm in some wells. The cause of ultra-high calcium mud in piedmont tectonic belt and the corresponding countermeasures were put forward.
