滨南-利津断裂带白云岩储层裂缝研究
|
摘要
从裂缝与地层曲率的关系、白云岩储层地震反射波沿层相干处理与解释、白云岩储层裂缝地震剖面解释、白云岩储层地层曲率解释以及白云储层地层反射振幅、频率特征等方面阐述了白云岩储层裂缝发育规律,由此预测出白云岩储层裂缝发育区,地层曲率高值区是油气富集的场所,可以对本区未钻井区储层发育情况进行评价和预测,为老区新层系勘探及老区开发打开新局面。
The fracture-growing area of dolomite reservoir can be predicted through discussing the growth regulation of dolomite reservoir fracture from such aspects as the relationship between fracture and formation curvature,the formation-following coherent process and interpretation of reflected seismic-waves in dolomite reservoir,seismic-section interpretation of dolomite reservoir fracture,the interpretation of dolomite reservoir curvature,the characteristics of reflected seismic-amplitude and frequency of dolomite reservoir.According to this article,the high level of formation curvature area can be the rich area of oil and gas.The research can be used to evaluate and forecast the growth situation of reservoir in those undrilled areas,thus it can be very helpful for oil and gas exploitation and exploration in mature field.
