摘要： 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。

Abstract: Luxi area of Junggar basin is rich in hydrocarbon resources, and in recent years, a series of lithologic hydrocarbon reservoirs have been found during hydrocarbon exploration of Sangonghe formation of Jurassic in Xiayan nose structural belt, which reveals great prospects in shallow layers. In this paper, technologies including sedimentary reservoir geological modeling, seismic attribute prediction, wave impedance inversion and data object visualization analysis are adopted to synthetically identify five lithologic traps, such as northern Well Madong-2 trap, Wellblock Madong-3 trap, eastern Well Madong-3 trap, southern Well Xiayan-6 trap and southern Well Xiayan-3 trap. The total area of these traps is 361.7 km2, the deepness of highs ranges from 2 150 m to 2 270 m, and the largest closure in eastern Well Madong-3 trap reaches 460 m. The synthetical analysis indicates that the lithologic traps are developed in Xiayan nose structural belt, and the geological conditions are favorable for forming lithologic hydrocarbon reservoirs.
