利用测井资料评价地层压力方法研究

地层压力是石油勘探、开发设计以及施工过程中的一个最重要的参数,准确预测地层压力是防止井壁失稳、提高钻井效率、节约钻井成本的必要条件。本文主要阐述了利用测井资料预测地层压力的诸多方法。在对某油田几个区块的研究基础上,发现这些方法都有自己的局限性,并经过进一步地研究得到了它们各自的适用条件。

The formation pressure is the most important parameter for petroleum exploration ,design for development and building process. Accurate to predict formation pressure is necessary condition to protect the bofehole wall,to enhance the efficiency,and save drilling cost. This article describe the ways that using logging data to predict the formation pressure. On the base of study about a oil-field,we found that these ways have different limitations,and after further study ,we obtained the favourite conditions for every method.
