摘要/Abstract

摘要： 研究了四氧化三锰与传统的加重材料( 重晶石、铁矿粉) 按不同质量比加重的高密度钻井液的滤失造壁性。实验结果表明, 对采用相对单一的加重材料加重的高密度钻井液, 当四氧化三锰与重晶石和铁矿粉按较优的质量比复配时, 球形的四氧化三锰小颗粒对重晶石和铁矿粉大颗粒的充填效果较明显, 得到的泥饼较致密。当四氧化三锰与重晶石、铁矿粉分别按1∶4和2∶3的质量比复配加重时, 高密度钻井液滤失量小, 而且泥饼渗透率较低。

Abstract: Wall building properties of highdensity drilling fluid weighted with manganese tetroxide and traditional weighting materials（barite, iron ore powder）in different proportion were studied. Experimental results show that highdensity drilling fluid weighted with the compound of manganese tetroxide and traditional weighting materials were synthesized in the optimum proportion, the effect of small size and spherical manganese tetroxide particles filled into large size barite or iron ore particles was more obviously than one single weighting materials. When highdensity drilling fluid was weighted with manganese tetroxide with barite and iron ore respectively according to the quality ratio of 1∶4 and 2∶3, filtration and permeability of cake was lower.
