应用广义S变换频谱分解技术识别松辽盆地三肇凹陷泉头组三-四段的河道砂体
|
摘要
松辽盆地三肇凹陷东部地区泉头组三-四段储层以河道砂岩为主,具有单层厚度薄、横向变化快等特点。本文将基于广义S变换的频谱分解技术应用于厚度为1～5 m的河道砂体的识别,取得了良好的效果。据此编制了研究区的河道砂体预测图,经钻井验证,证明它是对薄层河道砂体有较强识别能力的有效技术。
Channel sandstone is dominated reservoir in Fuyu oil layer hosted in Members 3-4, Quantou Formation in the eastern Sanzhao Sag,Songliao Basin,which was characterized by thin beds and rapid facies-changing transversely.In this article,a technique of Generalized S Transform spectral decomposition was briefly introduced,and then applied in recognition of channel sandbodies with the thickness being between 1 and 5 meters.The results showed that a good quality could be obtained for seismic interpretation.Based on the interpretation,the distribution map of channel sandbodies was compiled,which predicted interesting or potential belts in the eastern Sanzhao Sag.Two drilling wells demonstrated the predication being correct, and indicated the technique of Generalized S Transform having a stronger ability in recognizing thinner channel sandbody effectively.
