摘要
分析了地热钻井对泥浆的要求，高温热液下对粘土性能和化学处理剂的影响规律，及其对热储开发的严重后果；设计了地热钻井泥浆体系和试验程序；推荐了非热储层和热储层井段所不同的泥浆配方和相关的造浆材料及化学处理剂。
The requirements of geothermal drilling formud,the effect of high一temperature on the property ofclay and chemical treatment ,and the big troubles socaused for the development of thermal reserves were anal-ysed.The mud system and test procedure of geothermaldrilling were designed.The mud prescriptions and associ-ated mud一making materials and chemical treatments ofnon一thermal reservior layers were suggested for the con-struction of drilling well of high一temperature thermalheld under 260℃.
