井间地震资料解释方法技术及其应用
|
摘要
利用井间地震成像资料可以对地层、构造、储层等地质目标进行精细解释,其精度是地面地震资料的10倍以上。介绍了井间地震资料的特点,阐述了井间地震资料的解释思路,建立了井间地震资料解释流程。在SL油田LJ地区进行了井间地震资料解释,结果表明,利用井间地震资料可以解释出常规地面地震资料不能发现和确定的小(微)构造和小断层,精确描述由常规地面地震资料无法分辨的储层沉积模式,建立高质量的地质模型,提高储层描述的精度,从而掌握井间剩余油的分布情况及其控制因素,指导油田的进一步开发。
Crosshole seismic imaging data can be used in interpreting geo- logical objects in detail,such as stratum,structure,reservoir etc, with its accuracy being ten times higher than that of the surface seismic data.For crosshole seismic data.the characteristics are in- troduced,the interpretation clues are elaborated,and the interpre- tation workflow is established.In LJ area,SL oilfield,the cross- hole seismic data is interpreted by such workflow.Some micro structures and fractures are clearly shown,which cannot be shown in conventional seismic sections.The reservoir depositional model is described in detail,which cannot be recognized by conventional sections.A high quality geological model is established,which has improved the accuracy of reservoir description.The interpretation results of crosshole seismic data can be utilized to analyze distribu- tion features and control factors of the remaining oil among wells, providing guidance for the further development of the oilfield.
