摘要
评价工作液侵入所造成的地层损害是保护储层的钻井完井技术的基础工作．本上应用高温高压多点长岩心损害评价系统，对西部某油田侏罗系岩心进行了泥浆滤液侵入实验研究．所获得的滤液侵入深度、损害深度，损害程度及岩心含油饱和度变化等方面的结果，在理论上和实际应用上有一定价值．
The evaluation of the formation damage caused by mud filter invasion is a fundamental study to protect reservoir in well completion techniques.The authors in this paper make use of the multi-pressure differential and resistivity core measurement system to carry out an experiment on the simulation of the mud filter invasion with Jurassic cores from West China Oilfield.The results obtained,e.g.the relations between invasion length ,damage length,damage degree as well as the changes of oil saturation, thus offer some valuable models both in theory and practice.
