摘要
楚雄盆地是我国南方重要的中生代沉积盆地 ,盆地具有烃源条件好、圈闭类型多、生储盖条件好、资源潜力大等特点 ,而成为滇黔桂地区中、古生代大型盆地中最有希望取得突破和发展的盆地。云龙凹陷位于楚雄盆地东缘隆后沉积区 ,其内古生界海相地层保留相对较完整。具有长期稳定沉降、海陆相烃源岩丰富、勘探目的层多、埋深适中等特点。中部断弯构造带圈闭发育 ,圈闭面积大 ,闭合度高 ,资源量大 ,是首选的有利勘探区带。
Chuxiong Basin is an important Mesozoic sedimentary basin in South China. The basin is most hopeful of making a breakthrough and development in the large-sized Mesozoic and Paleozoic basins in Dian-Qian-Gui region, because it is of such characteristics as fair hydrocarbon source conditions, multiple-type traps, good source-reservoir-seal conditions and a large resource potential, etc. Yunlong Seg is located in the east edge behind-the-uplift sedimentary area of Chuxiong Basin, where the Paleozoic marine strata are relatively complete, being of the properties as long-term stable subsidence, abundant marine-continental source rocks, multiple exploration target zones and moderate burial depths, etc. The fault-warping structural belt in the central part of the seg, where the traps are developed, being of big areas, high closures and large resources, is the first-chosen beneficial exploration zone.
