江汉平原海相地层经历了多期盆地演化与构造运动的叠加改造,导致了中、古生界油气演化的复杂性,产生了成因多样、成藏规律复杂的油气藏,形成了包括古隆起发育区、“晚期成藏”立体勘探区、构造活动相对稳定区、逆冲推覆体发育区等多个勘探领域。在对各个勘探领域成藏特点分析的基础上,优选出了有利勘探区带和勘探目标,为早日打破平原海相勘探停滞不前的局面奠定了坚实的基础。 The marine facies in the Jianghan Plain experienced superposition and remodeling of multi-period basin evolution and tectonic movement, resulting in the complexity of oil and gas evolution in the Meso-Paleozoic, generating reservoirs with various causes and complicated reservoir forming rules, Area, “” late accumulation "three-dimensional exploration area, the tectonic activities of relatively stable area, thrust nappe development area and other exploration areas. Based on the analysis of reservoir forming characteristics in various exploration areas, favorable prospecting zones and exploration targets are optimized, laying a solid foundation for breaking down the stranded seawater exploration in an early time.
