阐述了白音查干凹陷的勘探历程和勘探思路由构造油气藏向隐蔽油气藏的转变。采用凹陷类比的方法明确了隐蔽油气藏勘探的区带和靶区,指出了勘探潜力,通过勘探实践获得较好的效果。又在勘探实践的基础上总结规律与认识,积极探索,基本摸清了锡林好来地区油气成藏的特征与油藏类型。针对不同类型的油藏,分区带提出了勘探部署思路,使该区油气勘探步入良性循环,也为凹陷展开寻找隐蔽油气藏提供了方法和思路。
The exploration process of Baiyinchagan depression and its exploration idea are explained from the transformation of tectonic reservoirs to subtle reservoirs. Using the method of sag analogy, the zones and target areas for subtle reservoir exploration are identified, the exploration potential is pointed out, and the better results are obtained through exploration. Based on the exploration practice, the author summarized the laws and understandings and actively explored the basic characteristics of the hydrocarbon accumulation in the Xilai region of Xilin and the types of reservoirs. In view of different types of reservoirs and zoning, exploration and deployment ideas are put forward to make the exploration of oil and gas in the area a virtuous cycle, and also provide methods and ideas for finding hidden subtle reservoirs in the depression.
