摘　　要：通过大庆外围油田不同区块多种体系钻井液对岩心的固相损害程度、液相损害程度和总体损害程度室内试验数据分析,阐明了钻井液对大庆外围油田低渗透油层的损害程度,明确了今后钻井过程中油层保护的技术对策。This paper has analyzed the experiment data of the core solid phase damage degree, liquid phase damage degree and overall damage degree from many kinds of system drilling fluid in different regions of Daqing peripheral oilfield. It clarifies the oil reservoirs damage degree by drilling fluid in Daqing peripheral oilfield, and gives the technical countermeasures of reservoirs protection during drilling course in the future.
