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, the Sanghe tectonic zone of Baiyinchagan depression mainly focused on the exploration of the tangential anticline in the deep Tengger Formation, and found poor oil exploration. To this end, a rolling exploration guideline is proposed, in which shallow layers are the main exploration targets, and the geological characteristics and hydrocarbon accumulation in the Sanghe tectonic zone are re-studied. All the segments are selected as the main target layers for research and evaluation, and the favorable trap targets are evaluated Rolling exploration well deployment. After nearly 3 years of rolling exploration and development of integrated research and implementation, and finally achieved substantial breakthroughs, the new discovery of Sanghe Shallow formation of a group of Ⅱ sand sandblast reservoirs, laying the scale for the area development and construction capacity Good foundation.
