准噶尔盆地陆西地区油气资源潜力丰富,近年来油气勘探在夏盐鼻状构造带侏罗系三工河组发现了一系列岩性油气藏,展现了浅层良好的勘探前景。采用沉积储集层地质建模、地震属性预测、波阻抗反演和数据体可视化分析等技术综合识别出玛东2井北、玛东3井区、玛东3井东、夏盐6井南和夏盐3井南等5个岩性圈闭。圈闭总面积361.7 km2,高点埋深2 150~2 270 m,玛东3井东岩性圈闭闭合高度最大达460 m.综合分析认为,夏盐鼻状构造带岩性圈闭发育,具备形成岩性油气藏的地质条件。
In recent years, a series of lithologic reservoirs have been discovered in the Sangonghe Formation of the Jurassic in the salt-saline-nose tectonic belt in the oil and gas exploration in recent years in the western part of the Junggar Basin. Using the technologies of geologic modeling of sedimentary reservoirs, prediction of seismic attributes, inversion of wave impedance and visualization of data body, it is possible to identify the north of Ma Dong 2, the east of Ma Dong 3, the east of Ma Dong 3, and the south of Xia Salt 6 And Xiayan 3 well south 5 lithologic traps. The total area of traps is 361.7 km2, and the burial depth is 2 150-2 270 m. The closure height of the eastern lithosphere in the Madong No.3 well reaches up to 460 m. According to a comprehensive analysis, the lithologic traps of the summer salt- With the formation of lithological reservoir geological conditions.
