seismic cross-section

Through the structural interpretation of seismic sections, using the restoring method of balanced geological cross sections, the TGN 9615 and AGH 15 deformational sections were examined by restoring balancing method, the result was within error range. So the interpretation plan was rational.

通过对地震剖面的构造解释，运用平衡地质剖面的恢复法，对TGN-9615地震测线与AGH-15地震测线变形剖面进行了平衡检验，其结果都在误差范围内，表明解释方案是合理的。

On seismic profile cross-cut the channel, it generally presents as a lenticle with flat top and concave bottom and has the character of infilling in reflection.

河道砂岩体在横切河道的地震剖面上一般表现为充填反射状的顶平底凹的单透镜体；

Structure form in time domain seismic cross-section often distort, such as high point deviate, attitude of stratum ( direction and angle of dip) deform away from the true.

时间域地震剖面上的构造形态时常发生畸变，例如高点偏离，地层产状（倾向、倾角）失真等。

It can describe precisely the cross hole reservoir by using synthetically the kinematic and dynamic features through using travel time and frequency feature of cross hole seismic first break for joint tomographic imaging for seismic velocity of stratum and for Q value.

通过利用井间地震初至波的旅行时及其频率特性进行地层地震速度和岩石Q值的联合层析成像，就可以综合利用地震波的运动学和动力学特征对井间储层进行更精确的描述。
