高分辨率层序地层学在海坨子地区隐蔽油藏勘探中的应用
|
摘要
运用高分辨率层序地层学中基准面旋回原理和"转换面"理论,在海坨子地区青山口组—姚家组钻井、岩心、测井、地震等资料综合研究基础上,建立了高分辨率层序地层格架,同时对该区层序发育特征和沉积体系进行了分析研究,明确了该区不同方向物源对沉积体系演化的控制作用。研究结果认为,该区层序格架内主要发育砂岩上倾尖灭油藏、断层-岩性油藏、砂岩透镜体油藏和构造-岩性油藏4种隐蔽油藏,应根据所处的构造位置和发育层序有针对性地寻找不同类型隐蔽油藏,对该地区隐蔽油藏勘探有一定的指导意义。
The theories of base-level cycle and "transform surface" in high resolution sequence stratigraphy are used to build a formation framework and to analyze sequence development and sedimentary system based on com-prehensive study of drilling,coring,logging and seismic data from Qingshankou -Yaojia formation in Haituozi area.The control action of different sedimentary sources on sedimentary system evolution is understood.It is thought that 4 types of subtle reservoirs had developed within the sequence framework in this area,including sandstone updip pinchout reservoir,fault-lithology reservoir,sand lens reservoir and structural-lithologic reservoir.Different types of subtle reservoirs shall be explored according to structural location and sequence development.
