摘要

车排子地区浅层新近系沙湾组岩性油气藏的有利储集层为"泥包砂"背景下的滩-坝相砂体,该砂体含油后在地震上表现为是短轴状-强振幅突然中断、亮点特征明显、速度降低,波形特征表现为强波谷-强波峰的组合关系。近年来,以宽频带高分辨率处理、高分辨率本征值相干、正演模型、储层反演、油气综合检测等技术,使准噶尔盆地克拉玛依油田首次在新近系发现较大油藏,也为盆地南缘前陆斜坡带新近系油气勘探开辟了新的领域。
Shallow Neogene Shawan Formation in Chepaizi area is a lithological reservoir. Its favorable reservoir is composed of beach-bar facies sandbody in an environment of "sand wrapped by mud". After bearing oil, the sandbody appears seismically short axis-strong amplitude discontinuing suddenly, spot-point being very obvious and velocity decreasing. And after bearing oil, the sand appears a compound shape of both strong wave trough and strong wave peak. In recent years, large oil reservoirs for the first time in Neogene of Karamay oilfield, Junggar Basin, have been found by some technologies, such as broadband high-resolution processing, high-resolution eigenvalue cohence, forward model, reservoir inversion and hydrocarbon detection. These acknowledges also provide a new exploration domain for Neogene at slope belt of southern margin in the basin.
