摘要： 塔中Ⅰ号坡折带是塔中地区奥陶系碳酸盐岩油气聚集十分有利的区带,为典型的溶洞储集体。岩溶缝洞的发育在地震剖面上表现为“串珠状强反射”。为了对小尺度的溶蚀孔洞和裂缝发育带进行预测,在地震资料处理中,突出保幅叠前道集处理,强化去噪技术攻关,通过井控处理改善反褶积效果,以提高奥陶系内幕资料的分辨率。应用各向异性叠前时间偏移技术进一步改善了塔中奥陶系内幕反射特征。

Abstract: Tazhong No.1 slope break as a typical karst cavern body is a very favorable domain for hydrocarbon accumulation of the Ordovician carbonate reservoir in Tazhong area, Tarim basin. The feature of fractures and caves is characterized by string beads-like reflection in seismic profile. The methods for prediction of the small-sized caves and fractures developing zones in seismic processing include amplitude-preserved prestack gather processing, noise-removal approach, well-control treatment to improve deconvolution effect in purpose of increasing resolution of the Ordovician inside information. Also, the inside reflection feature of Tazhong Ordovician is further improved using anisotropic prestack time migration technique.

Key words: carbonate reservoir, seismic data processing, relative amplitude remaining, well-control treatment, anisotropy, prestack time migration
