结合塔里木盆地北部碳酸盐岩储层地质特征,开展了储层预测方法技术研究,包括储层精细成像处理技术、三维相干体处理技术、地震特征参数提取及分析技术、波阻抗反演技术、三维可视化解释技术、成像测井技术、长源距声波全波测井技术以及裂缝综合概率模型技术等。建立了一套适合塔里木盆地北部碳酸盐岩储层预测技术系列。应用该技术系列,预测了塔河油田碳酸盐岩储层的裂缝和溶洞发育带,并得到了钻探证实。

A suite of methods has been developed to tackle the special geology of carbonate reservoirs in northern Tarim Basin. These methods include 3D fine seismic imaging, 3D coherence cube, seismic attribute extraction; impedance inversion, 3D visualization interpretation, image longing, long distance sonic logging and fracture probability model. The fracture and karst development zones in carbonate reservoirs predicted by the suite of the methods are verified by drilling.
