地震—地质综合储层预测技术在大庆油田G533区块的应用
|
摘要
针对大庆油田G533区块葡萄花油层三个砂层组中各种粒级的砂岩交互分布,声波测井曲线不能完全反映地层岩性变化,进而给岩性识别、储层分布预测带来困难,为此研究地震—地质综合解释技术和应用策略,对储层进行预测。地震—地质储层预测技术包括构造精细解释、地震反演、地震属性分析、信息融合技术等,通过结合定性与定量分析及地质、测井与地震一体化思路,特别是采用电阻率拟声波反演及频谱成像衰减属性频谱分解技术可以提高油气检测的精度。
Considering the interactive distribution of sandstone with different grain sizes in P11, P12 and P13 three sand sets of Putaohua reservoir in Gu-533 block of Daqing Oilfield, the sonic logging data is not able to totally reflect the lithologic change of strata, which further brought about difficulty in lithologic recognition and prediction of reservoir distribution. For that reason, the prediction of reservoir is carried out by studying seismic-geologic integrative interpretation technique and application strategy, which included fine structural interpretation, seismic inversion, seismic attributes analysis, information fusion technology etc. The precision of hydrocarbon detection has been improved by combination of qualitative with quantitative analyses, and geologic, logging and seismic integral idea, especially using pseudo-acoustic resistivity inversion and spectrum imaging attenuation attribute and frequency spectrum decomposition technique based on high-resolution time-frequency analysis theory.
