融频反演技术在J 31块薄储层预测中的应用
|
摘要
为了探索应用常规地震资料预测辽河盆地J 31块薄储层的方法,在对地震反演技术分析及提高分辨率原理的基础上,提出优势频率融合的思路,首先联合开展谱模拟反演和地震波形特征指示反演,再提取各反演结果的优势频率进行融合,并对融合后的成果数据进行解释,最后较为准确地预测了J 31块薄储层分布特征,指导下步油气勘探开发工作。研究结果表明:J 31块薄储层沿断层向东南方向展布,面积约1.2 km2,并通过J 34井钻井证实了预测结果的可靠性;基于谱模拟反演和地震波形特征指示反演结果,分别提取低频模型0~9 Hz的低频成分、谱模拟反演9~45 Hz的频率成分以及地震波形特征指示反演45~120 Hz的高频成分进行优势频率合并,可以对8 m左右的薄储层进行预测。该研究成果可为同类型储层预测提供借鉴。
In order to discuss the feasibility of thin reservoirs prediction based on traditional 3 D seismic data of block J 31 in Liaohe basin,the spectral simulation inversion technology and face controlled geological statistics inversion technology were used jointly based on the analysis of resolution principle and seismic inversion principle. First of all,it is necessary to carry out the rock physics analysis of target interval and carry out the spectral simulation inversion technology and face controlled geological statistics inversion technology research simultaneously. We extract the dominant frequency component from inversion results and integrate them into a data cube. Finally we interpret the outcome data and predict distribution of thin reservoirs with the threshold value. The following results have been achieved: the thin reservoir of block J 31 extends towards the southeast of the fault,with an area of about 1. 2 km2,and the prediction results have proved to be reliable by J 34. Based on the result of spectral simulation inversion and face controlled geological statistics inversion,we extract the low frequency component 0 ~ 9 Hz of low frequency model,the frequency component 9 ~ 45 Hz of result of the spectral simulation inversion,the high frequency component 45 ~ 120 Hz of result of face controlled geological statistics inversion and integrate them into a data cube. With this data,the 8 m thin reservoir can be predicted. This research provides reference for the prediction of same reservoir.
