摘要
通过岩心观察及人工微地震资料结合前人研究成果,尚家油田扶杨油层裂缝产状相对单一,大多以单条形式出现,规模相对较小,且充填严重,其裂缝走向以北东东向或北西西向为主。结合松辽盆地区域构造演化历史,认为尚家油田扶杨油层裂缝主要是在嫩江组沉积末期构造反转期形成的。利用曲率法预测出尚家地区扶杨油层顶面曲率高值区主要分布在尚家油田西南部D121井—D122井一线和中南部的A12-3井—A12-2井—A112-124井一线,是研究区扶杨油层裂缝发育相对集中区域。
through the observation of core and artificial micro seismic data,combining previous research results,that are known the altitude of fracture in F,Y oil layers in Shangjia oil field is relatively single.The fracture is mostly in the single form,relatively small and seriously filled.The trend of fracture is mostly in the east north east and west north west.Combining with the tectonic evolution history in Songliao basin,it is considered that the fracture in F,Y oil layers in Shangjia oil field is mainly formed in the period of the structure reversion,which is in the last sedimentary phrase of Nenjiang formation.By using curvature method,it is predicted the high value area of surface curvature in F,Y oil layers in Shangjia oil field is mainly distributed in the line of the D121 Well-D122 Well in the southwest and the line of the A12-3 Well-A12-2-A112-124 Well in the south,which is relatively concentrated fracture area in F,Y oil layers of the research area.
