摘　　要：苏德尔特油田布达特储层属浅变质裂缝性潜山油藏，储层缝洞普遍发育，既是主要储集空间，又是油气渗流通道。借助油藏描述、测井解释和油藏工程方法，通过统计分析、室内研究和矿场试验，在裂缝性潜山油藏富集成藏主控因素、油水分布规律、有效储层识别、块状潜山避射高度、合理采油速度、不规则网络潜山合理驱替方式及注水受效影响因素等方面形成了一些认识和突破，为海拉尔盆地油田开发提供了技术支持，也为国内同类油田注水开发提供了借鉴。The Budate Reservoir of Sudeerte Oilfield belongs to the epimetamorphic fractured buried hill reservoir. Fractures and cavities, which are the main reservoir space and the seepage channel of hydrocarbon as well, develop well and universally in the reservoir. By means of reservoir description, log interpretation and reservoir engineering methods and through the statistical analysis, laboratory study and field experiment as well, some understandings and breakthrough have been obtained in the following aspects, such as the main controlling factors of hydrocarbon accumulation in fractured buried hill reservoir, oil-water distribution pattern, identification of effective reservoir, unperforated height of massive buried hills, reasonable oil production rate, the reasonable displacement method of irregular fracture network buried hill reservoirs and the influencing factors of waterflood response, which provides technical support for the oilfield development in Hailar Basin, and provides reference for waterflood development in the similar domestic oilfields.
