摘要:
总结太古界变质岩裂缝性储层特征,针对该类变质岩油藏岩性多样、储层介质类型复杂、有效储集层识别难和储量参数确定难的特点,形成基于电阻率差比法和三孔隙度比值法的裂缝识别综合概率法,建立利用常规测井资料划分缝洞孔隙储层发育程度的标准; 采用电成像裂缝识别技术和孔隙度频谱分析技术,结合偶极子声波测井资料分析地层各向异性的方法判断裂缝特征、定量计算裂缝及缝洞孔隙度参数; 采用压汞资料建立基质孔隙含油饱和度的确定方法; 采用经验法确定缝洞孔隙的含油饱和度。研究成果在胜利油区桩海地区、东营凹陷王庄地区太古界变质岩油藏储量评估中完成多井测井评价,取得了较好的效果。
Abstract:
The metamorphic rock reservoir in Archaean is characterized by multiple rock lithologies, complex reservoir media, so it is hard to identify the effective reservoirs and determine the reservoir parameters. Through characteristics study on fractures in conventional and imaging log curves, worked out is the fracture identification comprehensive probability method based on resistivity contrast and porosity ratio method, and set up is the standards about discriminating fracture-porous reservoir developments. Electricity imaging log data, porosity spectrum analyse technique and DSI and FMI log data are used to identify fracture features, quantitatively calculate fracture and cavern porosities; The matrix pore oil saturation is obtained from mercury injection data; And the empirical method is used to get fracture and cavern pore oil saturation. The above methods are successfully used in log evaluations of Archaean metamorphic rock reservoir in Jiyang depression.
