地震标定中的测井资料精细处理方法及应用
|
摘要
在岩性油气藏的勘探过程中,利用测井资料标定地震解释层位是一项最基础和重要的工作。面对各种质量和来源的测井资料,传统的测井数据处理方法已难以满足地震标定的要求。这里结合岩性油气藏的特点,针对不同时期井眼扩径条件下采集的测井资料,提出了用于地震标定的环境影响校正、降分辨率、降速度,和低速带的增速校正等一套完整的测井精细处理方法。通过在准噶尔盆地的应用,使地震标定的相关系数有了大幅度提高。
During the process of lithologic oil-gas exploration,using logging data to calibrate the seismic interpreting horizons is the most basic job.But traditional calibration methods can not satisfy the requirements of seismic calibration jobs in the face to various well logs data with different quality and sources.Considering the characteristics of lithological reservoir and various well logs data which were acquired at different period and bad well bore environment,the paper proposes a set of methods of well log fine processing for seismic calibration,including environmental correcting,well logs resolution reducing,acoustic velocity reducing and velocity increasing of low velocity zone.Then results of the methods applied to Junggar basin are shown in the paper,which prove that these methods can effectively enhance the correlation coefficient of seismic calibration.
