摘　　要：利用自行设计的HTHP岩心滤失简易装置,近似模拟井下条件形成泥饼,并考察不清洗、清洗、清除并清洗3种情况下岩心与水泥浆的剪切胶结强度；同时,用金属棒模拟套管进行相应实验。研究表明：钻井液润湿性对固井Ⅰ、Ⅱ界面胶结强度的影响非常大,与水基钻井液相比,油基钻井液形成的界面胶结强度降低了近15％。因此,在设计前置液时合理使用润湿反转剂很有必要。Used self-designed HTHP core filtration simple apparatus, similarly simulated borehole conditions to form mud cake, and examined shear cementing strength between core and cement slurry innot cleaning, cleaning, cleating and cleaning conditions. Moreover, used metal stick to simulate easing and did corresponding experiment. The result was shown that the effect of the wettability of drilling fluid on cementing.strength of Ⅰ and Ⅱ interfaces in cementing job was enormous; compared to water-base drilling fluid, the interface cementing strength formed from oil-base drilling fluid decreased by 15%. Consequently, it is very necessary to use wettability reversal agent when designing pad fluid.
