苏德尔特油田布达特群潜山油藏裂缝储层测井评价

Well logging evaluation on fractured reservoirs of buried hill oil reservoirs in Budate Group of Sudeerte Oilfield

针对苏德尔特油田布达特群潜山变质岩裂缝油藏岩性复杂、储层介质类型复杂、有效储层识别难和储量参数确定难的特点,开展了裂缝储层特征的综合研究。在总结该区岩心裂缝特征和测井响应特征的基础上,形成了一套针对变质岩裂缝储层测井综合评价的方法,通过实际应用测井解释符合率在86%以上,较好地解决了布达特群变质岩潜山裂缝油藏测井综合评价技术难题,为该区储量评价和开发方案的编制与实施奠定了基础。

The metamorphic fractured reservoirs in buried-hill in Budate Group of Sudeerte Oilfield in Halaer Basin have the characteristics of complex lithology, complex reservoir medium types, as well as the difficulty in identifying effective reservoirs and reserves parameters. In view of these, the fractured reservoirs features was researched comprehensively. Based on core fracture features and log response characteristics,a set of complex evaluation method for the metamorphic fractured reservoirs was established. Practical application proved it can solve the problem of complex well logging evaluation for the metamorphic buried-hill fractured reservoirs of Budate Group with log interpretation coincidence rate of 86% above, and established the foundation for reserve evaluation as well as for the development plan framing and implementation.
