【摘要】：本论文以塔河4区奥陶系鹰山组缝洞储集体为研究对象,在前人研究的基础上,利用储层地质学、碳酸盐岩沉积学、测井地质学及开发地质学等理论和方法为指导,系统总结了不同储集空间和储集类型在钻井、录井、测井、地震属性等方面的响应特征,开展了单井缝洞储集体划分与识别研究;在此基础上,结合岩溶古地貌、古水系特征以及区域岩溶研究成果,分析了塔河4区奥陶系缝洞储集体发育的主控因素,建立了各类缝洞储集体的评价标准和发育模式,指出了其平面分布规律;同时结合已有的油藏三维地质模型及油藏开发生产特征,参考国内外碎屑岩剩余油研究成果,建立了研究区五种典型的剩余油分布模式,分析了其平面分布规律。研究结果表明:塔河4区奥陶系主要发育三种储集体类型.:裂缝-孔洞型储层、洞穴型及裂缝型储层,测录井响应特征明显,各类储集体之间以相对致密段相隔;根据岩溶发育强度及规模,纵向上可将塔河4区奥陶系缝洞储集体划分为两大类六小类,分别建立了各类缝洞储集体的评价标准;在单井缝洞储集体划分、识别及评价的基础上,分析了影响塔河4区奥陶系缝洞储集体发育的主控因素,建立了奥陶系缝洞储集体发育模式,指出了其平面分布规律;利用已有的油藏三维地质模型,参考国内外其它油藏,系统总结了五种剩余油分布模式,预测了塔河4区奥陶系剩余油平面分布特征。
[Abstract]:This paper takes Tahe District 4 Ordovician Yingshan formation fracture and cave reservoir as the research object, on the basis of previous studies, using reservoir geology, carbonate sedimentology, logging geology and exploitation geology and other theories and methods, the paper systematically summarizes the different types of reservoir space and reservoir in drilling, logging, logging response the characteristics of seismic attributes, the single well fracture cave reservoir research division and recognition; on this basis, combined with the ancient karst landform, drainage characteristics and regional karst research results, analysis of the 4 District of Tahe Ordovician fracture cave reservoir development of the main control factors of fracture and cave reservoir evaluation standard and development mode, and points out its planar distribution; combined with the 3D reservoir geological model and reservoir development and production characteristics of the clastic rock of residual oil refers to the domestic and foreign research results, the study area was established in five The remaining oil distribution of typical model, analyzes its planar distribution. The results show that the development of Tahe 4 District Three Ordovician reservoir types: fracturedvuggy reservoir, cave type and fractured reservoir, logging response characteristics, between various types of reservoirs in phase of tight interval; according to the karst development intensity and scale, longitudinal can be Tahe 4 Ordovician fractured vuggy reservoir is divided into two categories and six types, respectively set up various types of fracture and cave reservoir evaluation standard; in the single well fracture cave reservoir classification, identification and evaluation based on the analysis of the impact of Tahe District 4 main Ordovician fracture cave controlling factors of reservoir development, establish the Ordovician fractured vuggy reservoir development model, and points out its planar distribution; using 3D geological model of the reservoir of the other reservoir at home and abroad, summarizes the five kinds of residual oil distribution model, forecast The distribution characteristics of the remaining oil in the Ordovician system in the 4 area of Tahe.
