摘要
针对苏北盆地高邮凹陷SB油田上第三系戴南组由扇三角洲相控制的构造-岩性复合油气藏储层平面变化大、砂泥岩薄互层的特点,建立了针对主要含油层系戴二段的测井约束反演技术思路和流程,主要包括测井曲线预处理、井震标定及子波估算、建立低频模型、反演关键参数测试等环节,通过测井约束反演完成了对储层的定量预测和描述,从而为正确认识该区油藏的储层分布提供了准确依据,勘探效果显著。
In consideration of the characters of plane changes in structural-lithologic reservoirs and glutenite interbed of upper Tertiary of Dainan Formation in SB Oilfield of Gaoyou Sag of Subei Basin,which was controlled by fan-delta facies,the technical method and process of logging constraint inversion are established for 2nd member of Dainan Formation,including logging curve preprocessing,well-seismic calibration,wavelet extraction,low-frequency model establishment,and key parameter testing etc.It is found out through practical petroleum exploration that log constraint inversion is a useful method to reservoir quantitative prediction and description and it provides precise evidence for predicting the reservoir distribution and better exploration results are obtained in the studied area.
