中文摘要：
在对塔里木盆地奥陶系古潜山低渗裂缝性碳酸盐岩储层地质特征进行分析的基础上,利用人工裂缝岩样进行了应力敏感评价试验。结果表明,试验岩样存在较强的应力敏感性,平均渗透率损失92.48%,裂缝宽度下降76.37%。基于储层应力敏感性试验分析,对目前使用的正电胶钻井液体系配方进行了改进,取得了良好的应用效果。
英文摘要：
The stress sensitivity evaluation test was made by using artificial fracture rock sample based on characteristic analysis on Ordovician buried hill low-permeability fractured carbonate reservoir in Tarim basin. Test results show that testing samples present strong stress sensitivity with 92. 48 percent loss of mean permeability and 76. 37 percent drop of fracture width. MMH drilling mud formula was improved according to analysis of stress sensitivity test to reservoir and the good application effect has been obtained.
