摘　　要：在岩心观察、薄片鉴定、常规测井解释的基础上,结合成像测井资料对塔里木盆地哈6区块奥陶系碳酸盐岩储层特征研究表明,该区奥陶系碳酸盐岩储层主要集中在一间房组及鹰山组,储层基质孔隙发育较差,裂缝和溶蚀孔洞较发育,储集空间主要为洞穴型、孔洞型、裂缝型、裂缝-孔洞型。通过成像测井与常规测井、岩心资料进行标定,提出了各类型储集空间的成像测井识别标志,克服成像测井解释的多解性,为今后对未取芯井段利用成像测井准确识别井下地质特征奠定基础,降低生产成本。With well development of rift and karst, carbonate rock stratum might be a high quality of reservoir. But the carbonate reservoir has the characters of strong anisotropic distribution. Conventional logging is hard to meet accurately and efi3ciently identifying the underg- round geological features. By means of studying the characteristics of Ordovician carbonate reservoir, we find out the fractures and vugular solution porosity is well- developed and the matrix porosity is poorly developed. The large - scale cave, rug, fracture,fracture - vug are the major types of reservoir in the study area. Through calibrating the FMI with conventional logging and the drilling core material, we put forward the various types of reservoir space identification marks and overcome the multi- solution of the FMI.
