摘要： 塔河油田1号区块奥陶系碳酸盐岩储集层埋深大、非均质性强,给储集层的预测和勘探布署带来极大的难度。在正确认识储集层基本特征的基础上,利用地震波振幅、频率、波形变化识别储集层;利用相干体计算技术、地震测井反演技术、速度分析技术、主曲率分析技术研究储集层缝洞发育情况;利用三维可视化技术研究岩溶发育情况,实践表明,这种方法是可行的,可以在一定程度上预测碳酸盐岩储集层发育有利区域。

Abstract: The carbonate reservoir of Ordovician in No.1 Block of Tahe oilfield is of big buried depth and serious heterogeneity, which bring about great difficulty to reservoir prediction and exploration arrangement. Based on correct understanding of basic feature of the reservoir, the variations of amplitude, frequency and waveform of seismic wave are used to recognize the reservoir; many techniques such as coherent events calculation, seismic well log inversion, velocity analysis and main curvature analysis are applied for study of fractural and vuggy development in the reservoir; and 3-D visualized technique is utilized to research karst development. Practice shows that such a method like these is feasi-ble and can be used for prediction of the favorable exploratory areas in developed carbonate reservoirs to some extent.
