摘要：

评价工作液俊入所造成的地层报害是保护储层的钻井完井技术的基拙工作.本丈应用高泥高压多点长宕心摘害评价系统，对西那某油田休罗系若心进行了泥浆泌液任入实脸研究.所获得的涟液设入深度、摘害深度，很害程度及宕心含油饱和度变化千方面的结果，在理论上和实际应用上有-定价值.

关键词: 涟液任入, 使入深度, 报害深度, 损害程度

Abstract:

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.

Key words: Mud filter invasion, Invasion length, Damage length, Damagd degree
