摘要
准噶尔盆地东部(以下简称"准东")吉木萨尔凹陷二叠系芦草沟组(P2l)为典型致密油特征,纵向上发育上、下2套"甜点"储层,裂缝发育程度是"甜点"储层评价的重要指标,常规地震资料无法准确识别。针对该储层特点,提高裂缝预测精度,在准东吉25井区首次实施了高密度全方位三维地震勘探,并采用炮检矢量片处理技术,改善了裂缝储层的成像效果,对开展方位各向异性和裂缝特征研究起到了重要作用。
The Permian Lucaogou Formation in Jimsar Sag of Junggar Basin had typical characteristics of tight oil.There were two sets of dessert reservoirs longitudinally.The degree of fracture development was an important index for the dessert evaluation.However,it can not be accurately identified through the general seismic data.According to the reservoir characteristics,in Well JI25 3D,high-density full-azimuth 3Dseismic exploration is first implemented in the east of Junggar Basin.The main purpose is to improve the prediction accuracy of the fractures.high density 3Dseismic data are used as a wide-azimuth seismic processing method,the offset vector tile technique provides the most effective and precise data in geophysics for the basic seismic processing.The results of offset vector tile processing show that this approach has great advantage in many aspects,such as azimuthal anisotropy,fracture detection,it is beneficial for seismic imaging.
