摘要
在研究崖13-1构造泥岩压实过程中,发现未经校正的泥岩压实曲线无法真实地反映实际情况,在影响声波时差诸因素中,气层和钙质对声波时差的影响最为突出,笔者提出了相应的校正方法,并用于该构造的压实规律与油气运移研究。
During study of shale decompction,it is recognized that uncorrected shale compaction curve,derived mainly from the sonic data,can not cor- relate well with the database aquired.Analysis thereof is conducted and results in identification of gas pays and calcareous beds which have the most pronounced effects on the sonic loggings.Measure of correction subsequently is proposed and then applied to shale decompaction and hydrocarbon migration in Ya 13-1 gas field area.
