corrected oil

This paper studies deviation of old method to forecast oil ( gas)-water contact. This method is corrected as formation water saturation.

文章在充分研究了原有压力法计算油（气）水界面海拔公式中存在的缺陷后，指出应引入含水饱和度参数对公式进行修正。

The corrected resistivity value of the fresh water mud invasion for different pore structures were given through comparing the time-lapse logging, the oil-base coring wells and the array induction logging with the conventional logging and combining with software inversion.

通过时间推移测井、油基泥浆取芯井、阵列感应测井与常规测井对比统计分析，结合软件反演，得出了不同孔隙结构类型淡水泥浆侵入电阻率校正值。

The experimental modal analysis of the giant clamp type oil tank structure of a transformer was made by this paper. The mathematical model for dynamic analysis of the oil tank structure was corrected by the more precise modal parameters obtained by the modal experiments.

本文对巨型变压器钳夹式油箱结构进行了试验模态分析，并用模态试验得到的精确模态参数，检验和修正了油箱结构的动态分析数学模型。
