【摘要】 地层压力是石油勘探与开发中的重要参数之一.求取地层压力的方法较多,其中声波时差法是较为有效的方法.在沉积物中,颗粒之间孔隙的大小,反映了沉积物的压实程度,而孔隙度大小和声波时差有关,故可建立地层压力与声波时差的定量关系.这样可通过沉积物中泥岩的声波时差值求取地层压力.计算时差应充分考虑影响精度的因素.更多还原

【Abstract】 Formation compaction is one of the important parameters in petroleum exploration and development phase. At present,there are many methods to compute formation compaction. The methods of interval transit time is one of useful ways.The size of porosity among sediment grains reflects the degree of compaction, and the porosity is related to interval transit time. Therefore,formation can be calculated from the value of interval transit time in shale. Factors affecting the accuracy of transit time calculation should be considered.更多还原
