Evaluate Of High Quality Seismic Data

The Yushulin oilfield is located in eastern slope of Sanzhao seg of central sag zone in the northern part of Songliao basin. Its main oil-producing formations are Fuyu and Yangdachengzi oil layers of mesozoic group cretaceous. Its reservoir is fluvial facies sediment. Main sandstone is positive circle channel sandstone with calcium in the beneath, and microelectrode curve is box distribution function. Its secondary oil-producing formation is Yaoyi part of Putaohua oil layer. Its reservoir is delta front sediment. Main sandstone is subaquatic distributary channel sandstone, and microelectrode curve is box distribution function. Two oil layers are mainly fault and lithologic deposit.Through seismic disposal, interpreting, instruct drilling work to two-dimension seismic area of the well shu-121, three-dimension seismic area of the well shu~103 area in the Yushulin oilfield, the paper has proved research outcome, also proved it effective to development oilfield that high discernibility disposal increases interpreted precision of old seismic file.Moreover, it extensive applied the interpret way of contrast of high low frequency sectioned to eliminate the false and retain the true in the project, avoiding drop valid signal result to irrelevant disposal way. Maintain use new information, contrast old information, integrated explain to forecast favorable oil and gas concentration zone, to instruct development work of Yushulin oilfield. Seeing from situation that encounter oil layer when drilling, the paper acquires very good applied effect.
