识别断块油气藏、岩性油气藏及裂缝油气藏等多种复杂油气藏类型，对老油区继续勘探意义重大。以ＲＭ油藏描述系统为核心，结合ＩＥＳＸ、ＥＬＡＮＰＬＵＳ以及神经网络等新技术，对二连盆地洪浩尔舒特凹陷努格达构造的构造、储集层及油藏类型进行了分析研究。该区主要勘探目的层阿尔善组为扇三角洲沉积，区内发育了河口坝和分流河道微相，物源主要来自东南的大兴安岭隆起。储集层岩性为含凝灰质、云质长石岩屑中细砂岩和含砾砂岩，孔隙式胶结，以次生孔隙为主，为典型中低孔特低渗型储集层。受构造、地层、岩性等因素影响，分布有地层岩性构造、构造和地层岩性３种类型的复杂油气藏。油藏弹性能量弱，产液量低，需经压裂改造后才具商业性产能。应用波阻抗反演方法，准确预测了Ｈ１０７井地层岩性油藏的分布范围，为油藏评价和储量计算提供了依据。经过油藏描述预测认为，Ｈ１０８井西构造为有利的含油带，是下一步勘探的有利目标。图３表１参２（邹冬平摘） Identification of fault block reservoirs, lithologic reservoirs and fractured reservoirs and other complex types of reservoirs, continuing exploration of the old oil region is of great significance. Taking the RM reservoir description system as the core and combining with the new technologies such as IESX, ELANPLUS and neural network, the structures, reservoirs and reservoir types of Nugunda structure in Honghaoershute Formation in Erlian Basin are analyzed. . The Aershan Formation, the main exploration target of the area, is fan delta deposition. The estuarine dams and distributary channel microfacies developed in this area. The source of the aishang deposits mainly come from the Daxinganling uplift in the southeast. The lithology of the reservoir is tuffaceous, fine feldspar and pebbly sandstone in the lithic feldspar lithology. Porosity cementing is mainly pore secondary porosity, which is a typical low porosity and low permeability reservoir. Affected by tectonics, strata and lithology, there are three types of complex reservoirs: lithology, tectonics and lithology. Reservoir elastic energy is weak, low liquid production, after the transformation of the fracturing only commercial capacity. The wave impedance inversion method is used to accurately predict the distribution range of lithologic reservoirs in H107 well, which provides a basis for reservoir evaluation and reserves calculation. After the reservoir description predicts that H108 west well structured as a favorable oil zone, it is a favorable target for further exploration. Figure 3 Table 1 Reference 2 (Zou Dongping pick)
