摘要(Abstract)：
本文通过物理模拟实验，研究岩心在起钻过程中由于降压脱气而损失的油、水饱和度。根据实验资料作出了饱和度校正曲线，并对中检4-8井岩心的饱和度进行校正，结果是满意的。
Abstract
In this article, using physical simulation method, we discuss the loss of oil and water saturations from cores caused by degasing as pressure drops during pulling out. Based on experiment data we've made a saturation correcting curve and satisfactory results are obtained through correcting the saturation values from cores taken from well Z-J-4-8.
