摘　　要：由于有机硅产品质量差,研制了深井钻井液用抗高温降粘剂,有机硅氟共聚物(SF),并进行了室内SF钻井液配方试验和综合评价。结果表明,在深井的高温、高固相、高密度条件下,SF钻井液各项性能均优于有机硅钻井液和无毒钻井液。该处理剂抗温超过230℃、加量少,与水泥有较好的相容性。现场应用2口井表明,SF钻井液处理简单、维护周期长、劳动强度低、应用效果理想。Organic silicon-fluorine polymer (SF) is studied as a new viscosity reducer. Tests indicate SF drilling fluid show much better than organosilicon fluid and non-loxicity fluid in all respects under high temperature, high solid content and high density condition, the dosage is low and the compatibility with cement is good. .Applications in 2 wells proved its advantages such as simple maintenance. long stable period andtemperature stability.
