摘要
江75区块萨Ⅰ油层组上部近南北向延伸的条带状异常带表现为弱振幅的现象一直没有得到合理的地质解释,制约了勘探部署。通过对地震属性、钻井及沉积相分析认为,萨Ⅰ油层组振幅异常是由不同成因的沉积单元叠置造成的,萨Ⅰ油层组上部属性切片大面积的强振幅是早期席状砂、河口坝和水下分流河道错叠连片的反映,弱振幅是末期发育分流河道切割下伏砂体且被萨零油层组的深湖-半深湖相泥岩充填的响应;而萨Ⅰ油层组中下部条带状强振幅则为晚期河道下部砂体沉积的响应,大面积的弱振幅则为萨Ⅰ油层组早期深湖-半深湖相泥岩的响应。
The abnormal band extended to the north and south was presented weak amplitude in SaⅠ Reservoir Group of Block Jiang 75,it has not been rationally interpreted in geology,by which the exploration of SaⅠ Reservoir Group was restricted.Based on seismic attribute and analysis of drilling and sedimentary facies,the results indicated that amplitude anomaly of the reservoir group was caused by different geneses of superimposed sedimentary units.Its upper attribute slice of strong amplitude in the large areas was the interlaced overlay reflection of early sand sheet,mouth bar and subsea distributary channel.The weak amplitude was the response of distributary channel developed at the late stage that was cut by underlying sand body and filled with deep lake-half deep lake mudstone.Its banded strong amplitude was the response of the sedimentary facies of lower channel sand body at the late stage,while the weak amplitude at a large scale was the response of early deep lake-half deep lake mudstone.
