摘要:
针对河道砂体中的含油气性预测的难题,以沾化凹陷三合村地区新近系馆陶组上段为研究对象,采用Geoscope系统基于双相介质理论的油气检测技术进行含油气检测。根据双相介质具有的“低频共振、高频衰减”特性,采用小时窗滤波分析,对给定时窗内的地震数据进行频谱分析,并对给定的高低频敏感段内振幅谱进行能量计算,再对计算结果进行相减,进而得到能够定性表征储层油气富集程度的结果。这些结果能够灵活地以剖面或平面的形式显示,同时对计算结果与实际钻井资料进行对比分析,充分验证了该预测方法的实用性与准确性,可以有效地指导沾化凹陷三合村地区馆陶组的勘探与开发。
Abstract:
In order to solve the difficulty of predicting the hydrocarbon content in channel sandbodies,the upper part of the Neogene Guantao Formation in Sanhecun area of Zhanhua Sag is taken as the research object,and the oil and gas detection technology based on the dual-phase medium theory of the Geoscope system is used to detect the oil and gas.According to the characteristics of “low-frequency resonance,high-frequency attenuation”of dual-phase media,the little time window filter analysis is used to analyze the frequency spectrum of the seismic data in a given time window,and calculate the energy of the amplitude spectrum in the given high and low frequency sensitive section. And then the calculation results are subtracted to obtain a result that can qualitatively characterize the oil and gas enrichment degree of the reservoir.These results can be flexibly displayed in the form of sections or planes. At the same time,the calculation results and actual drilling data can be compared and analyzed,which fully verifies the practicability and accuracy of the prediction method,and can effectively guide the exploration and development of Guantao Formation in Sanhecun area of Zhanhua Sag.
