摘要
准噶尔盆地腹部以单斜构造背景为主,近几年所揭示的隐蔽油气藏类型虽然主要以地层、岩性油气藏为主,但仍然呈现多样性的特点,成藏主控因素也具有相对的多样性。从成因角度分析,盆地腹部砂层、不整合面、断层等输导条件控制了油气藏的分布和富集,盆地中央发育的“车-莫古隆起”控制了油气藏的调整和改造。通过不断地总结,中国石化西部新区逐渐总结出一套处理、解释相结合以模式为指导的隐蔽圈闭地震识别技术。
The central Junggar basin is dominated by monoclinal stractures. Despite the fact that the subtle reservoirs discovered in recent years are mostly stratigraphic and lithologic, the reservoir types show diversification,so are the main controlling factors of reservoiring in the basin. Analyzing from the angle of genesis, the carrier conditions of the sand formations, uncomformities, and fault in the central basin, control the distribution and enrichment of hydrocarbons. The Che-Mo palaeohigh developed in the central basin controls the adjustment and modification of the reservoirs. By summarizing the past experiences, a set of seismic recognition technologies that integrate seismic processing with interpretation and are guided by patterns are gradually developed for the exploration of frontiers in western China.
