Logging analysis of Ordovician carbonate reservoirs in Shunbei 1 region, northern Tarim Basin

摘要: 塔里木盆地北部顺北一区奥陶系碳酸盐岩储层非均质性和各向异性强,储层类型复杂。以成像测井资料为主,结合常规测井、岩心等资料,将其储层类型根据其空间组合方式的不同,划分为洞穴型、裂缝孔洞型、裂缝型。其中主断裂以洞穴型储层为主,次级断裂主要发育裂缝、裂缝孔洞型;并开展了与相邻区块储层类型的横向上对比。结合声电成像测井资料,初步探讨了岩心上比较发育的水平缝的测井响应特征,成像处理结果表明这种类型裂缝渗流能力较差。Abstract: The Ordovician carbonate reservoirs in Shunbei 1 region of the northern Tarim Basin have a high hete-rogeneity and anisotropy, and the reservoir type is complex. The reservoir types were classified into the cave type, fractured hole type and crack type according to their spatial combination based on imaging logging data and combined with conventional logging and core data. The main faults are dominated by cave reservoirs, and the secondary fractures are mainly fractures and fractured cavities. The reservoirs were compared with adjacent reservoirs. The well logging responses of the horizontal fissures on cores were preliminarily discussed combined with electro imaging logging and acoustic imaging logging. The results of imaging treatment showed that the fracturing seepage ability is poor.
