摘　　要：考察了正交实验优化得到的无固相钻井液配方的抗温性、配伍性、腐蚀性、岩心伤害性和对粘土水化分散的抑制能力。结果显示抗温90℃以上,与油田水配伍,腐蚀速率低于0.025 mm/a,岩心伤害率小于30%,对粘土的水化膨胀抑制能力强。With the optimized formula by orthogonal experiment, the solid free drilling fluids were prepared and screened on temperature resistance, compatibility with oil field water, corrosion, core damage and resistance of the elay＇s hydration expansion. It was found the drilling fluids can resistant the temperature of 90 ℃, and it is compatible to the oil field water, its rate of corrosion is less than 0.025 mm/a, and the rate of core damage is less than 30 %, it can also resistant the elay＇s hydration expansion effectively.
