Introduction
This section presents a general overview of the problem of log interpretation and examines the basic questions concerning a formation’s potential hydrocarbon production which are addressed by well logs.
测井工作分为两个阶段:野外资料录取阶段和 资料处理解释阶段.
The borehole environment
• The borehole environment in which logging measurements are made is of some interest from the standpoint of logging tool designs and the operating limitions placed upon them.
The next annular region of diameter d i is the flushed zone whose
resistivity is donated by Rxo the uninvaded or virgin zone with resistivity Rt
Figure 2-4. Schematic model of the borehole and formation used to describe electric logging measurements and corrections.
F • The drilling fluid, or mud. The salinity of the drilling mud
ranges between 3000 and 200,000 ppm of NaCl ,This causes invasion of a porous and permeable formation by the drilling fluid.
The log format conventions are presented , and an example is given which indicates the process of locating possible hydrocarbon zones from log measurements .

探测技术中的位置
可以解决的问题: 1. 油气储层的评价问题 2. 相关的地质问题 3. 工程问题及地层的机械性能 4. 油气开发问题 5. 为地面地球物理勘探资料解释提供参数 6. 与其它资料结合进行储层空间描述与盆地
探测技术中的位置
矿场地球物理 油矿地球物理 钻井地球物理勘探 地球物理测井: 钻孔中进行的各种 地球物理探测方法 的统称. 1927年由法国 Schlumbeger公司 的创始人 Schlumbeger兄弟 俩创立的.
地球物理测井是用各种专门的仪器放入井内, 沿井身测量井孔剖面上各种物理参数随井深 的变化曲线,并根据测量结果进行综合解释, 用于判断岩性、确定油气层及其它矿藏的一 种间接手段.
• Well depths
• The deviation of the borehole, which is between 0 and 5 onshore, and between20 and 40 offshore.
• The temperature, at full depth, ranges between100 and 300
• it is important in terms of the disturbance it causes in the surrounding formation in which properties are being measured.
The Borehole Environment
• Some characterization of the borehole environment can be made using the following set of generalizations:
The Borehole Environment
• To account for the distortion which is frequently present with electrical measurements, a simplified model of the borehole/formation has evolved ,which is shown schematically in Fig. 2-4
