摘要
通过大量实验分析了目前几种常用于评价磺化沥青产品抑制性方法的缺陷,从磺化沥青抑制井壁垮塌的机理出发,提出了采用"线性膨胀法"和"动态封堵法"相结合来评价磺化沥青产品抑制性的新思路。
The defects of several methods currently used for evaluating the borehole wall collapse inhibition performance of sulphur- ized-asphalt products for drilling fluid are analyzed through a lot of experiments. From the mechanism of the sulphurized-asphalt in- hibiting the borehao wall collapse, a new evaluation method for the inhibition performance of sulphurized-asphalt products is put for- ward, which is the combination of ＂linear expansion method＂ and ＂dynamic plugging method＂.
