摘要
K71井区块是胜利油区垦西油田的主体开发区,主要含油层段为馆陶组和东营组,现已进入油田开发中后期,仍具有一定的开发潜力。由于受分辨率的限制,采用常规地震资料难以准确描述井间砂泥岩薄互层横向分布,而采用井间地震资料却能获得井间地质目标极为精细的图像。本文利用高分辨率井间地震资料,在小层精细对比的基础上,结合深度域反演剖面,描述两对井井间薄储层的横向变化,建立了K71井区块井间砂泥岩薄互层精细地质模型,为以后三维精细地质模型的重建、开发层系的进一步调整打下了坚实基础。
The K-47 well zone is major development area of Kenxi oilfield in Shengli Oilfield,the main oil-bearing segments are Ng and Ed that enter the middle-late period of oilfield development but still have some development potential. Using ordinary seismic data is difficult to accurately describe the lateral distribution of cross-hole thin-interbedded sandstone/mudstone because of the limitation in resolution, but using cross-hole seismic data can obtain more precious image of cross-hole geologic targets. Using high-resolution cross-hole seismic data and on the basis of fine correlation of minor layers the paper described the lateral variation of cross-hole thin reservoir for two pairs of wells and created the fine cross-hole thin interbedded sandstone/mudstone geologic model in K-47 well zone in combination with inverted section in the depth domain, which laid a solid foundation for later recreation of 3-D fine geologic model and further adjustment of development formations.
