三维地震资料在四五家子油气田开发中的应用
|
摘要
三维地震资料较精确地反应了地下油气地质信息 ,在油气田的开发过程中具有十分重要的作用。文章论述了三维地震资料在四五家子油气田开发过程中的具体应用与效果分析。首先研究了四五家子构造的标准地震波和特征地震波 ,给所确定的地震标准波和特征波赋予其地质含义 (即层位标定 ) ,然后研究了四五家子构造特征和断层组合 ;最后 ,应用三维地震资料对研究油气的纵向分布和储层砂体横向预测进行了探索 ,尤其是在油气的横向预测方面 ,研究成效显著。在四五家子油气田应用三维地震资料开发的近十年过程中 (到目前为止 ) ,应用三维地震资料在该油气田部署开发井数十口 ,成功率在 99%以上
D seicmic data can accurately reflect the subsurface oil and gas geological information,playing an important role in oil and gas field development.The application of 3 D seicmic data in Siwujiazi oil and gas field development is expounded and its result is analyzed in the paper.At first,the standard seismic waves and specific seismic waves of Siwujiazi structure are studied,then the geological meanings(i.e.horizon calibration) of the two kinds of waves are entrusted,and then the characteristics and fault assemblage of Siwujiazi structure are investigated in the paper.The achievement is remarkable in studying vertical oil and gas distribution and lateral sand body reservoir prediction,especially in studying the latter,by use of 3 D seismic data.In course of Siwujiazi oil and gas field development for about ten years (up to now),few tens of development wells have been disposed according to 3 D seismic data and their success ratio if more than 99 percent.
