Study on the evolution of paleo-uplift in southeast Sichuan

[摘要] The deepening understanding of the geological structure of large paleo-uplift in the basin is often accompanied by important oil and gas exploration discoveries. The abundant oil and gas exploration results in the early stage show that the luzhou paleo-uplift is one of the important petroleum accumulation structural units in the sichuan basin. At the same time, the formation and evolution of luzhou ancient uplift were also affected by a variety of geological factors. It is a joint response of the internal deformation of the Yangtze plate and the orogenic movement of the peripheral block in the indosinian period, and a natural place to study the basin-mountain coupling relationship and the basin superposition transformation process. By means of a large number of seismic reflection profile and drilling data, combined with field exploration and other data, the temporal and spatial distribution characteristics of luzhou ancient uplift are described in detail. Combined with the tectonic background of the study area, the formation of luzhou ancient uplift was further analyzed, and the genetic mechanism model of luzhou ancient uplift was proposed. Through analysis, it is concluded that the indosinian luzhou ancient uplift developed in the southeast of sichuan basin, and its long axial strike is from northeast to southwest, which is a typical compressive and superimposed ancient uplift.
