柴达木盆地古隆起主要类型及油气勘探方向
MAIN TYPES AND HYDROCARBON EXPLORATION DIRECTION OF THE PALEO-UPLIFTS IN THE QAIDAM BASIN
摘要
Abstract
The paleo-uplifts in the Qaidam Basin are widely distributed and have great exploration potential.In order to indicate the exploration direction of the Qaidam Basin, the structural styles, sedimentary characteristics, evolution stages, kinematic characteristics and reservoir-forming laws of the main paleo-uplifts are summarized in this article through the interpretation of seismic data and the example analysis of discovered hydrocarbon reservoirs in paleo-uplifts in recent years.The paleo-uplifts in the basin are divided into 4 main types: stable type, active type, residual type and extinction type.At the same time, the distribution of paleo-uplifts in the basin has a certain regular pattern: the paleo-uplifts mainly developed on both sides of the deep faults, and the boundary conditions of different properties of basin determined the type of the paleo-uplift.The paleo-uplifts have superior reservoir forming conditions in the migration and accumulation of hydrocarbon, reservoir types, trap types, transportation conditions and preservation conditions etc.Therefore, two favorable exploration directions of the paleo-uplifts in the Qaidam Basin are confirmed: one is tapping the potential of the discovered hydrocarbon fields; the other one is the piedmont tectonic belt with relatively good reservoir conditions on the basin margin.关键词
