摘要(Abstract)：
针对辽河盆地大民屯凹陷沈143井区勘探程度低、构造相对简单、为岩性砂体油藏、储层薄的实际地质特点,将分频解释技术应用在该研究区的储层预测中,利用勘探目的层段的地震资料,通过傅立叶变换方法,进行频谱分析,在频率域实现储层横向变化规律的研究,其预测结果与实际钻井吻合得较好,圈定了砂体分布范围,确定了油藏边界,为研究区下一步部署井位提供了依据,也为研究区储层预测研究提供了新的技术方法手段。
Frequency-shared interpretation technique generates reservoir prediction in frequency domain by Fourier Transform and can calculate thickness time of reservoir.It is used for prediction of sandbody distribution in Shen 143 well area of Damintun Sag of Liaohe Basin.Prediction result coincides well with actual drilling data.This method provides geological reference for further exploration,and presents new technique for reservoir prediction.
