利用常规测井方法识别划分水淹层

Recognizing watered-out zones by using traditional well logs

根据测井曲线的水淹特征,分别对砂泥岩剖面和下套管的老井水淹层段进行分析,阐述了自然电位、电阻率、双频介电测井、人工激发极化电位、声波时差、中子伽马、自然伽马、热中子寿命及碳氧比等测井曲线识别划分水淹层的方法、技术及特点,指出提高水淹层测井解释方法实用效果的进一步实验研究工作.

The techniques and characteristics of recognizing watered out zones by using natural potential log, resistivity, dual frequency dielectric, induced polarization, acoustic move out, neutron gammar ray, natural gammar ray, thermal neutron lifetime and carbon to oxygen ratio log curves are presented. The recognition of the watered out zones of sand shale profile and old cased well is discussed according to the characteristics of single log curve and the compound characteristics of several log curves.
