测井资料检测地层压力的方法综述及评价

测井资料检测地层压力是钻井完成后的压力计算技术,它不仅可以评估研究区域的地层压力情况,还可以为石油钻井提供基础数据。在当前已有的压力检测方法中,大多数方法存在一定的局限性。针对这一特点,本文阐述了各种方法的基本原理,在此基础上指出了方法中存在的不足以及方法的适用条件。

The log data checks the formation pressure is the technique of computing pressure after drilling, the technique is no only can evaluate the pressure of region of interest, hut also provide the data for drilling. At present, most of methods of checking pressure by log data have some limitation. So the article expounds the basic theory of cach method in detail and points out the limitation and the applicable conditions of the method.
