摘要
地层孔隙压力是石油勘探、开发设计与施工的基础数据,准确的预测和掌握地层孔隙压力的大小,对石油勘探与开发有着极其重要的作用,尤其是对异常压力层段做出准确预测具有重大的工程价值和经济意义。介绍了基于“泥质沉积物不平衡压实造成地层欠压实并产生异常压力”原理和基于有效应力原理利用测井资料对地层孔隙压力进行预测的方法。
The formation pore pressures are the basic data of the oil explo ration, exploitation Planning and construction. Exactly anticipating and mastering the pore pressures plays an exceedingly important role in the exploration and exploitation, especially accurately anticipating the abnormal pressure zone has momentous engineering value and economic significance, This paper introduces the methods of anticipating formation pore pressures with logging data, one based on the theory that the disequilibrium compaction of argillaceous sediment brings about the uncompaetion of formation and results the abnormal pressure, another based on the effective stress,
