Potassium salt is the main raw material for producing potassium fertilizer, and it is a shortage mineral in China with the highest import dependency. Because of its buried depths (10～2 000 m), solubility, water absorption and fracture development, the special drilling technology is required. According to the drilling construction experience and characteristics of potassium salt at home and abroad, the study was made on core drilling machinery and equipment, drilling technology and flush fluid.
