摘要
Abstract
We study the changes and relation of acoustic velocity and porosity under normal temperature and pressure and high temperature and pressure with rock core test data from Suliger gas field.Rock porosity decreases logarithmically with pressure increasing and decreases slightly with temperature increasing.Rock acoustic velocity increases logarithmically with pressure increasing and decreases linearly with temperature increasing.With depth increasing,the effect of estimating pressure on acoustic velocity is about 10～30 times than that of temperature effect on acoustic velocity.Further study shows that porosity pressure affection factor decreases with porosity increasing and pressure affection factor of acoustic velocity increases with porosity increasing to different rock samples,therefore,it makes the relation of reservoir porosity and acoustic velocity become poor under normal temperature and pressure.关键词
