二连盆地白音查干凹陷成藏特征
|
摘要
二连盆地白音查干凹陷油气勘探已有30年历史,但直到2003年油气勘探才取得重大突破,在一度被认为没有油气聚集的地方,通过对老资料的重新认识,构建新的成藏模式,从资源评价、优选大型构造背景、寻找大砂体及其与构造背景的结合,到应用三维地震等技术精细落实小构造、小断块、小砂体等圈闭,创新勘探思路,发现高产富集油气田和优质规模储量。截至目前,油气勘探不断有新的发现,已先后发现桑合、桑合西、达尔其、达尔其西、翁特西和锡林浩来6个油田,探明石油储量数千万吨,新建年产能力10×104t。白音查干凹陷油气勘探的历史和经验,对其他老凹陷的风险勘探将有所启示。图7参22
The oil and gas exploration in the Baiyinchagan Sag,Erlian Basin,has been 30 years,with no breakthrough until 2003.In the area of being thought with no oil,some high-yielding prolific fields and high-quality scale reserves have been discovered by reexamining the old data to establish new reservoir formation pattern,and with new exploration concepts from resource evaluation,major structural background optimization,big sand body searching and its combination with structural background to applying 3D seismic technology and other technologies to identify the traps of small structures,faulted blocks and sand bodies.Many new fields have been discovered,such as Sanghe,West Sanghe,Daerqi,West Daerqi,West Wengte and Xilinhaolai,with proved oil in place up to tens of millions of tons and additional annual capacity of 10×104 t.The exploration history and experience in the Baiyinchagan Sag will throw new light for risk exploration of other old sags.
