【摘要】 塔河油田奥陶系碳酸盐岩储层的主要储集空间为溶蚀的孔、缝、洞。在大量岩芯标定的基础上,确定了测井可识别的4种储层类型:裂缝型、裂缝-孔隙型、孔洞型、洞穴型储层;研究了各种类型储层的常规测井、成像测井响应特征及测井识别方法;总结了影响储层判别的各种假储层现象,研究了似均匀溶蚀、燧石条带、白云岩化斑状灰岩、薄层状灰岩等假储层的测井响应特征及识别方法;采用成像孔隙度频谱法、成像分类判别法实现成像测井的次生孔隙度评价和多参数综合定量评价;在岩芯、成像测井资料标定的基础上,采用裂缝综合概率模型、双孔介质模型实现缝洞型储层的常规测井资料定量评价,在塔河油田奥陶系储层测井评价中取得了较好的效果。结合生产实际总结了本区奥陶系碳酸盐岩储层流体性质判别的4种方法,对缝洞型碳酸盐岩储层的流体性质判别进行探索。更多还原

【Abstract】 The main reservoir space of the Ordovician carbonate reservoir is the corroded pore, hole and fracture in Tahe oilfield. Based on the large numbers of core calibration, well logging data can be used to identify four reservoir types: fracture type, fracture and pore type, pore and hole type, hole type. The response character of the common logging and the imaging logging of all kinds of reservoirs and logging identifying methods were studied. A variety of fake reservoir of disturbing reservoir identifying was summed up. The fake reservoir logging response characters and identifying methods of the similar uniform corrosion, the chert banding, the dolomized por-phyritic limestone, the thin sill like limestone were studied. The secondary porosity and integrated quantificationally evaluation were carried out using the imaging sort distinguishing method, imaging pore spectrum analysis. On the basis of core and the imaging data, the reservoir was evaluated quantificationally using the common logging data through the integrated fracture probability model, double pore medium model. The logging evaluation in the Ordovician reservoir shows a better effect. Integrating the produce, four fluid identifying methods is summed up in Ordovician in this zone, which is a useful exploration method for the fluid identifying of the reservoir in the carbonation of fracture and hole type.更多还原
