【摘要】 准噶尔盆地车排子地区沙湾组薄砂体油藏埋藏浅、物性好、产量高,是中国石化胜利油田公司近年来重要的产能建设阵地,但由于油层较单一、砂体厚度薄、横向变化快、分布零散、隐蔽性强,一直没有取得重大突破,探井成功率不超过30%,滚动勘探开发风险较大。根据车排子地区沙湾组油藏发现井——排2井及其周围探井所获地质认识,依据高精度三维地震资料,从区域沉积相分析入手,查明沙湾组薄砂体成藏模式,利用正演模拟、滚动储集层描述、地震属性分析和油气检测等技术手段,形成了一套薄砂体滚动勘探开发技术,并利用其指导车排子地区滚动井位部署,取得了非常好的滚动勘探开发效果。更多还原

【Abstract】 The Shawan Formation thin sandstone reservoir in the Chepaizi area of Junggar Basin is shallow,has good physical properties and high production,and it is the important production front of Sinopec Shengli Oilfield Company in recent years.Because the oil layer is single and the sandstone thickness is thin with rapid lateral variation and subtle distribution,there is no great breakthrough,the success ratio of exploration wells is less than 30%,and the rolling E&P risk is great.According to the geologic understanding of Well Pai 2 and high precision 3D seismic data,the reservoir-forming model of thin sandbody in Shawan Formation was figured out by analyzing the regional sedimentary facies distribution.Then,applying the techniques of forward modeling,rolling reservoir description,seismic attribute analysis and hydrocarbon detection,we summarized a set of progressing E&P techniques of thin sandbody to guide the deployment of progressing wells.Good progressing E&P results are obtained.更多还原
