| Abstract: | Through measuring the displacement pressure of mudstone cap rock in member 2 of Yinggehai Formation of Yinggehai Basin,the linear relation between displacement pressure of cap rock and acoustic time was demonstrated,and the method to calculate the displacement pressure with acoustic time and seismic velocity data was put forward to.Then,based on acoustic time and seismic velocity data,the overpressure distribution of mudstone cap rock in the lower of member 2 of Yinggehai Formation was determined by means o... |
| Keywords: | displacement pressure mudstone cap rock gas sealing ability the second member of Yinggehai Formation Yinggehai Basin |
