摘　　要：白音查干凹陷桑合构造区2001年前主要以深部的腾格尔组滚动背斜为勘探目标,找油勘探效果差。为此提出以浅层为主要勘探目的层的滚动勘探方针,对桑合构造区重新开展了地质特征与油气成藏研究,优选都一段作为研究评价主要目的层,对有利圈闭目标进行评价与滚动勘探井位部署。通过近3年的滚动勘探开发一体化的研究与实施,终于取得了实质性的突破,新发现桑合构造浅层都一段Ⅱ砂组断鼻油藏,为该区投入规模开发建设产能打下了良好基础。Before 2001, in Sanghe structural area the rolling anticline in deep Tengge'er Formation was the target of exploration, where oil exploration affect was poor. Thus, it was proposed that shallow layers were considered as target zones of exploration, the geologic characters and hydrocarbon accumulation were restudied in the area, Ed1 was chosen as a main target zone of evaluation. The beneficial traps were evaluated and well location was deployed for rolling exploration. By implementing the integration of rolling exploration and development for years running, it is newly found that Ed1 Sand Group II is fault-nose reservoir, it provides a basis for large-scale of production in the area.
